Laptop battery news

Memup, digital entertainment specialist, is expanding its range of touch tablets with a new model, the NG SlidePad 9716DC. It follows a tablet we’ve tested recently, SlidePad NG 9716. The DC version has a dual processor heart as the previous chip has a single heart. Thus, the Dell Studio 1555 Battery performance should be better.

We spent some time with the touch pad Memup SlidePad NG 9716DC and here are our impressions during a complete test

The handling

Externally, the tablet Memup SlidePad NG 9716DC resembles nothing so much as NG version 9716. It is 4/3 as the iPad while almost all Android tablets is in 19/6. The NG SlidePad 9716DC is slightly thicker than the NG 9716. It measures 242.5 x187, 6×11, 8 mm and weighs 580 grams against 240.6 x187x8, 9 mm for the same weight.

The SlidePad NG 9716DC is equipped with two cameras (one for NG 9716). The first front is 0.3 Mp and the second back, 2 Mp. This is the minimum “vital”. There are two speakers.

In terms of connectivity, the NG SlidePad 9716DC has a headphone jack, a microUSB jack, a power connector, a mini HDMI output and a slot for memory cards microSD (up 32 GB). There are traditional buttons / off / standby and dual button to increase or decrease the volume. The microUSB jack allows you to connect a USB drive, a keyboard or a mouse via adapter supplied with the tablet. We appreciate it. In addition, the tablet is compatible with 3G.

The memory card has a location more easily accessible than the NG version 9716 which required removing a cover to insert the storage media.

Finishes the tablet NG 9716DC is correct and the device seems well made.

The tablet screen Memup SlidePad NG 9716DC measure 9.7 inches and displays a definition of 1024×768 pixels. It does not benefit an IPS panel. However, the colors are correct and brightness significantly. You can count on Wi-Fi b / g / n and Bluetooth missing on SlidePad NG 9716.

System and applications

The tablet Memup SlidePad NG 9716DC runs on Android 4.0.4 Ice Cream Sandwich. As the NG 9716, there is no overlay software. It can not (officially) to access the download platform applications Google Play Store. However, downloading and installing the firmware available on the manufacturer’s website, it appears.

The preinstalled Dell Inspiron E1505 applications are: Calendar, Aldiko, Camera, Brief Me, Calculator, Contacts, Email, ES Files Explorer, Gallery, Application Manager, GetJar (alternative platform for downloading applications), Clock, Music, Browser Norton Mobile Security, Office Suite, Search, Shazam and Video Player.

Note the presence of Norton Mobile Security application that helps protect your device against viruses. Even if it is a trial version, it’s nice to be aware of safety shelf since in theory, it is also stated that on a computer.

Performance

As noted in the introduction, Slide Pad NG 9716DC has a dual A9 Amlogic 8726-heart MX. The technical Memup indicates a frequency of 1.5 GHz while applications Elixir2 Quadrant Standard and display a maximum frequency of 1.2 GHz … It is associated with 1 GB of RAM. The tablet ships 16GB of internal memory with a little more than 11 GB are actually available for storing data and installing applications.

To evaluate the raw performance of the tablet, we submitted several measurement tools Quadrant Standard. The application is not SmartBench compatible with this tablet.

The SlidePad NG 9716DC fared significantly better than the NG version 9716. It is almost on a par with the Samsung Galaxy Tab 7.7.

Multimedia

The video player is capable of playing videos to AVI, MP4, MPEG, WMV, VOB, MKV, TS, TP, as well as JPEG, BMP, GIF and PNG. In audio, the tablet is compatible with MP3, WMA, FLAC, WAV, AAC.

HDMI output provides a Full HD picture on a compatible TV. The tablet Memup SlidePad 9716DC NG displays the movie on the TV but keeps the virtual control over the tablet, the screen remains active that was not the case with NG 9716.

For web browsing, the tablet allows a good display pages. We tested the terminal Browsermark and in SunSpider. Here are the results. Under Browsermark, the higher the score, the higher the fluid navigation and display elements fast. In SunSpider, the opposite is true.

Autonomy

The tablet is powered by a Dell Vostro 1320 Battery with a capacity of 5500 mAh (6000 mAh version NG 9716). With Wi-Fi on, brightness set to 50%, we were able to play a video loop for about 5 hours. This is less than the SlidePad NG 9716 which takes 6 hours.

Lumia 820 takes place on the medium-high range – due to its sheet – and strengthens the family of smartphones Nokia to Lumia 920 Lumia. Sold for 470 euros off grant, is a little less expensive than its elder, it is powered by the Windows Phone 8 system with a 4.3-inch (800 x 480 pixels) AMOLED screen, a Snapdragon S4 processor dual-core clocked at 1.5 GHz, 8 GB internal memory (over 7 GB available on SkyDrive) expandable via a microSDHC card, and a 8 megapixel sensor. Is Lumia 820 a good smartphone? The HTC 8 X which it faces a competition? Response in this testbed…

Lumia 820 displays a design of a clean, appealing to the eye but not frankly innovative genre – except perhaps the wide choice of colours.

Unlike the 920 Lumia, unibody, Lumia 820 has a modular shell (accessible battery, therefore, but SIM cards and memory pinned under the battery). what change the color of hull to the envi.

Is however preferred to touch gum, less rolling coatings.

Side stencil, the phone is not in the ultra-finesse or the lightness (160 grams anyway), but it fits in the Palm of your hand. Compared to the 920 Lumia, largest (4.5-inch screen) and heavier, it is obviously much easier to use regularly in one hand the 820. An important point for many users who do not wish to upgrade to a smartphone too big.

The 4.3-inch screen is equipped with a limited definition of… 800 x 480 pixels. At the present time, competitive, the density of pixels displayed here is clearly indented. A surprising choice on the part of Nokia. It is indeed not an entry-level smartphone… In front, its direct competitor the 8 X is equipped with a 4.3-inch screen also but with any other definition of 1280 x 720 pixel – identical to that of the 920 Lumia.

If the contrast ratio is very good, the maximum brightness is indented, with only 284 cd/m², against 410 cd/m² for the 920 Lumia, 374 cd/m² for the HTC 8 X and 500 cd/m2 for the iPhone 5. In terms of Colorimetry, the 820 is less faithful than his groin with a Delta E 7.4. A large majority of recent smartphones displays one of below 4. As a reminder, most the of of a screen approaches 0 and more true-to-life colors it displays.

The screen shows reagent and perfectly obeys the solicitations.

It should finally be noted the excellent initiative on the part of Nokia: allow owners of this phone (and Lumia 920) for use with gloves, with accuracy always last. A real plus for winter days! Would say, competitors, if you could provide the same treatment to all smartphones and tablets in the future, users in know you strong gre.

Interface and navigation

Windows Phone 8 is not a clean break compared to the 7.5 version. So far, the OS is evolving and offers now a few new features common to all terminals launched under this very nice system to use. We have compiled and detailed each of them (SkyDrive to share the calendar, notes, photos with different groups of contacts, the world of children, etc.) on this special page Windows Phone 8. Remember WP8 takes over the forces of WP7: integration of a suite agency link with an own account with 7 GB of free online storage on Skydrive notes to unify notes taken on the fly.

The range Nokia Lumia has many exclusive applications such as Nokia Transport, Drive Nokia, Nokia Music, or even Nokia Explore. All of these services offered free of charge are particularly significant, because effective and thoughtful like Nokia maps mapping system – common, itself, to all Windows Phone.

If Windows Store is not yet as well-stocked as iOS, in terms of games in particular, we appreciate to all test them, even those who are to be paid. SmartGlass app allows to enhance the experience on the side of video games to control an Xbox 360 (also available on Android and iOS app).

A few stars applications are still not on the shelves of the Store Windows. It notes, for example, the absence of Instagram and DropBox (but does have SkyDrive, share its data in the cloud).

Lumia 820 displays a beautiful reactivity and a nice fluidity in all circumstances (download apps, surf on the Internet… video playback), even when multiple applications run in the background. The integration of a stable system to a solid and well optimized technical configuration delivers good results and good behavior of the terminal on a daily basis.

Multimedia

Awaited for its qualities as excellent stamped photos by Nokia, Lumia 920 we had disappointed, with a non-homogeneous rendering and the marketed these last six months high-end smartphones below clearly. Lumia 820, also equipped with a sensor of 8 megapixel is doing better? Well frankly step. There again, it’s disappointing. It is certainly a hair better than older, somewhat less blurring and therefore more details posted on the edges of the shadow, but overall, it remains unsatisfied. The picture function will clearly not be the decisive factor that we would opt for this smartphone.

Windows Phone HTC 8 X, despite increased a bit exaggerated contours, is doing better and displays including more details on the whole image.

Finally, while Lumia 920 was doing very well in low light, 820 does it less well, but with a little light and without flash, it can get out of the correct images due to light conditions.

Lumia 820 takes advantage of some applications such as photo welcome such as Panorama and PhotoIntelligente, to create a picture “that’s Alright” from captured shots.

The quality of the video catches (so far in 1080p) is quite correct for a smartphone with a significant sound rendering.

The headphone output provides a high-performance sound reproduction without any distortion of the sound, all with good dynamics and a fairly correct maximum power. The external speaker is struggling to escape, with a notable saturation at high volume.

Equipped with a battery of 1650 mAh, Lumia 820 held fast the day with enough sustained use (SMS, Web, social networking, music, picture). Games and video, particularly intensive in energy resources, are more quickly lowering the autonomy of the device.

Spearhead Samsung Galaxy S III is simply the most anticipated Android smartphone of the year. The wait is over: here in our hands. Is it a worthy successor to the Galaxy S II?

In 2 years, Samsung has upset the landscape of Android smartphones. Party after HTC or Motorola, the Korean manufacturer has unsheathed a 2009 Galaxy S which has found a winning formula: design from all but the top components, a screen large enough and flashy to high printing, and it must be confessed, a certain resemblance with the iPhone in both lines in the dell Studio XPS 1647 battery user interface.

Upon its release, the Galaxy S was nevertheless opposed to sharp competition: HTC was including in front of smartphone performance, but also better finished, as the Desire HD. However, Samsung has widen its lead with the Galaxy S II, a successor signing ultrathin, lightweight, and benefiting from a dual processor heart. Become a reference in its domain, the Galaxy S II has naturally created a strong expectation of his successor. The latter was also awaited for … By Apple, which has meanwhile released its legal arsenal to defend its patents and design.

However, Samsung has taken its time to unveil the Galaxy S III, leaving especially enjoy HTC’s Mobile World Congress to get its new line One: no need to rush, since Samsung can now impose its own agenda. After mounting the buzz, the manufacturer can finally unveil its new baby!

Therefore more hype, but a true smartphone that will have to face competition. On paper, you could be disappointed by some technical and aesthetic choices of the Galaxy S III. However, upon closer look, the new Galaxy S may well impose natural successor to the GS II on the throne of best current smartphone.

Equipped with a quad processor heart home, Exynos 4412 Quad, a Super AMOLED screen with a resolution of 1280×720 pixels and a photo / video sensor 8 MP/1080p the Galaxy S III runs Android Ice Cream Sandwich . As usual, off Nexus S and Galaxy Nexus, Samsung has “customized” using its interface Touchwiz overlay, modified for the occasion. It’s not just because the smartphone embeds some additional keys, including S-Voice, a voice assistant that is reminiscent of some memories …

Design and ergonomics

Samsung was expected to turn on the design of the Galaxy S III. IPhone 4 to the latest HTC smartphones through the N9/Lumia Nokia 800, we have witnessed in recent years a move towards more materials and design quality “unibody” focusing on the fineness and uniformity … to the detriment of caches and removable covers. We therefore asked whether Samsung would not take and break the Dell Latitude E5400 Battery plastic design of the Galaxy S II battery cover and rather … low end. And the answer is negative: Samsung continues its momentum and renewed with the S III his own style. The hull of the smartphone is fully plastic cover keeping it thin, flexible plastic that can scare the first time you retire, but remains firmly in place, without play or cracking.

A short tour of the phone reveals the most classic choice: there is a 3.5 mm jack on the top, a micro USB port at the bottom of the hull, the volume buttons on the left and the lock button on the right. On the back, the camera / video is elevated relative to the rest of the hull, and indeed quite exposed to scratches. It is surrounded by a LED flash and a speaker. An objective video is on the front, with two sensors on which we will have the opportunity to return. Invisible in normal operation, the LED through the hull to blink when charging and notifications.

This dell latitude e6400 battery approach may therefore seem conservative, but it has an advantage at a time when more and more manufacturers seal their shell, Samsung continues to opt for a removable battery. We still regret the rim plastic imitation brushed metal: a bit of metal on a real high-end smartphone was not too many. But Samsung is Samsung, and if the materials used are not the most luxurious, all is well finished and inspires confidence when assembled.

The balance is quite successful outside: therefore move the components that drive the Galaxy S III, because this is where Samsung traditionally shines. After the Tegra 3 HTC One X, Samsung followed suit with no quad-core version of its Exynos home: Exynos 4412 Quad. This SoC ARM v7 is composed of 4 core Cortex A9, clocked at 1.4 GHz. The chipset is engraved in 32 nm. Compared to HTC One X is a little better on paper: the hearts of Tegra 3 operate at 1.3 GHz when used together, and spend 1.4 GHz when only the heart is used. In contrast, no pseudo fifth heart for low energy consuming tasks little.

Dell Inspiron 1320 GPU SoC is a Mali-400 MP4, responsible for leading a 4.8-inch Super AMOLED screen with a resolution of 1280×720 pixels and a resolution of approximately 306 dpi. Characteristics reminiscent obviously the Galaxy Nexus S III screen is slightly larger (4.8 against 4.65 inches) and pixel density a little lower, the Nexus amount up to 316 pixels.

As usual, critics criticize him its Super AMOLED oversaturated colors and features AMOLED display that reveals a small frame on the screen, still much less visible than on a Galaxy S II, Due to the resolution denser. However, the colorimetry of GS III is still more convincing than its predecessor, and the viewing angle is simply impeccable.

The camera offers some common characteristics for a high-end smartphone: sensor retro-exposed pictures of 8 MP, 1080p video, and features that seem to be common: f/2.6, focal length of 4mm maximum aperture of 2.76 mm. These are features quite satisfactory for a smartphone, and we’ll see in practice that the photos and videos take all their promises, but one could imagine that Samsung is playing brinkmanship and pass the bar as 12 MP Sony Xperia S and Dell Studio 1558 Battery.

In front, there is a goal generating video still shots of 1, 9 MP and 720p videos. Both sensors operate at 30 frames per second.

No change either on memory and storage. Regarding RAM, 1 GB is found, which is the maximum of the current smartphones. The phone is available in 16 and 32 GB and storage capacity can be expanded with a MicroSD slot that can add up to 64 GB! A good point, especially since HTC has removed the possibility of extension on its terminals One.

We arrive at wireless, and what more, if it is that Samsung has thought of everything? We pass on the 3G: HSDPA (21 Mbps) and HSUPA (5.76 Mbps) are supported. Ditto for the Wi-Fi compatible B, G and N. Bluetooth 4.0 is the game, and manages the GPS A-GPS. Classic, what …

What is less, even if the Galaxy S III is not the first Android smartphone to integrate, it is the presence of an NFC chip: it is especially designed to work with two integrated applications: Android beam, which is part of Ice Cream Sandwich, and S-Beam, an application for transferring files from Samsung, not working for the trouble between two Galaxy S III. A quick glance at the sensors to finish: the phone has an accelerometer, gyroscope, proximity sensor, compass and … barometer.

Galaxy S III runs Inspiron 1464 Android Ice Cream Sandwich, version 4.0.4 to be precise. Unsurprisingly, the manufacturer does not Android in its basic version, as on the Galaxy Nexus, but mostly with its TouchWiz overlay, or more precisely a variant exclusive to the Galaxy S III. If you have a Galaxy S II ICS in the past, you will have noticed that the differences between 2.3 and 4.0 are strongly erased.

The variant of the GS III named Touchwiz Nature, however, is more radical in its changes, and finally closer to the original spirit of Ice Cream Sandwich, as it was designed by Mattias Duarte, as imitation of iOS Touchwiz original. Should we see again a desire to avoid the wrath of Cupertino? Whatever the reason that prompted these changes, they are welcome, because the interface is both pleasant to use, while retaining the simplicity of the ICS “vanilla”.

Before going into the details of the interface, however, a difference back to the fundamental shot between the original spirit of ICS and the Galaxy S III: the virtual keys are not integrated into the interface as the Galaxy Nexus or Android tablets. As was mentioned earlier, Samsung has chosen to renew its usual ergonomics: a central physical button and two touch keys. The center button serves several functions: a simple press returns to the home screen and long press opens the list of recent applications. The two Dell Vostro 1520 softkeys are assigned to the parameter display, and back. ICS purists may prefer the Google approach, where we have a dedicated button to display the Application Manager, but can not find the time needed to hold down the center button too long. However, this change has a second consequence: the use of a smartphone button to display the options, while the practice advocated by ICS is more access to settings from the icon in the upper right of the interface.

Overall, the interface of the Galaxy S III is conspicuous by its simplicity. Samsung has sold a few effects such as scrolling carousel screens receptions reminiscent Sense, or manager of browser tabs Coverflow way, but in general, it is far from a Sense 4 which redraws all ICS sauce: Samsung, for example, kept the task manager minimalist and intuitive from the standard version of Android 4.0. In addition, we always appreciate the presence of shortcuts to disable the various circuits directly from the notifications panel.

Samsung additions occur especially in applications provided, as well as various small features added here and there, including using proximity sensors. All are not really necessary, and some even suffer a functioning quite random, but include particular Smart Stay, a feature that uses the front objective to detect your face, especially your eyes leave the screen on, or instead it off if you do not look. Other gestures are included rather original: Wear your phone to your ear after reading an SMS to call the recipient, place the Vostro 1015 screen side to disable ringtones … Why not!

Telephony

We will not stop raving about the telephony layer, but simply say that we did not notice any problem call quality is there, transmission and reception, and not worry proximity sensor that would cut a call inadvertently.

Multimedia

Key Samsung is also reflected in the media, and lose nothing of the main strengths of the Galaxy S II’s video support seamless. The reader has a home provided DivX Certified, and therefore reads, without adding a third player, almost all videos that gave him: DivX, Xvid, MKV, H264 … And what is more without re-encoding necessary.

We note in passing rather original functionality: the ability to display a video “picture in picture” over any application. It may seem a little gadget, just to show that the Exynos Quad was in the belly, but one can imagine cases where you want to keep an eye on a video while doing something else. However, the interface of a smartphone is not made for it, we never know where to place the window. It might be more interested on a shelf.

On the Dell Inspiron 1521 output video to the TV, the Galaxy S III provides an HDMI output via MHL protocol, but with one caveat: Micro USB connector with additional pin, it will be impossible, as we made the sad experience of use the adapter of the Galaxy S II. And in the absence of new adapter when our test, so we did not test this feature. In contrast, no problem regarding the DLNA, which works exactly as expected, and without a hitch.

The audio is a little less difference, even if Samsung provides a pleasant drive to use and feature rich enough: it manages profiles preset equalizer, but a real equalizer preset to suit his tastes. On this point, Samsung has not eroded the basic features of Ice Cream Sandwich as did HTC Sense on the 4. In addition to equalization, Samsung has also included some more or less useful effects: the spatial and improving clarity, so X-Fi, are quite effective, but adding reverb is superfluous. We regret, however, since the power of the processor allows clear lack of management fade or play “gapless”. However, the alternative is no shortage of players on the Play Store for more picky. We note in passing that the xps m1530 retains the FM tuner of its predecessor. It is always better than nothing.

Internet

We will not dwell on the Internet, because it is absolutely no surprise: there are Google applications (web browser, mail client Pop / Exchange / IMAP, Gmail …), and not much more. The web browser has a few “customizations” made in Touchwiz: tabs, for example, displayed horizontally and in 3D, so HTC Sense. However, unlike Sense 4, Samsung has not cropped on the boundary already binding, 8 tabs. We may regret the absence, by default, support for Twitter and Facebook, not even through a widget: Google+ is logically put forward.

Obviously, the screen of the dell xps m1330 is a treat for surfing and Ice Cream Sandwich forces, fluid scrolling and zooming is perfect. Despite the abandonment of Adobe Flash on mobile, you can always find a compatible version of ICS on Play Store, and again, videos and animations are no problem fluidity. It took until the monsters power as GS III to finally have a plug-in that delivers the performance expected of it!

Not much to complain about either side of the game: the higher resolution of the Galaxy S III is not flinching GPU Mali 400 MP4. The few games tested, including Riptide, Shadowgun and Dungeon Defenders are rotated perfectly fluid. In contrast, the presence of tactile buttons on the bottom of the unit increases the risk of accidental pressing holding the smartphone in landscape mode: we arrived to operate the Menu button during game in Riptide.

S-Voice: a clone of Siri without genius

The gossips say that they could not help it: the Galaxy S III incorporates its own alternative to Siri, the voice assistant in the iPhone 4S. The concept is the same, and application design is largely inspired from Apple: the bottom of the screen icon microphone can start a voice request. Once the above stated, it is sent to the server with a latency Samsung, and executed with a return speech.

S-Voice handles requests altogether classic call a contact, send an SMS, create a memo or event title play on the MP3 player, launch an application, search or learn about the weather.

In practice, we found imperfect speech recognition, especially for names. The application includes commands correctly but often tangled brush as soon as you place a contact, artist or song title in the equation. On this level, Siri seems more powerful, but still far from optimal though.

The problem of Dell Inspiron 1520 S-Voice, it was his lack of personality. Already, nasal voice is quite unpleasant. But above all, Samsung has not been able to reproduce what is part of the effect of “wow” Siri: humor and feel that exudes intelligence, even if it is absolutely not. S-Voice knows he has to respond to requests, and answer “I do not understand” when he does not speak English with a French accent for no reason. Do not try to be funny, or ask questions in a roundabout way, you will hit a wall.

In short, if the original is already more or less a gadget in the current state of things, this pale copy unoriginal and not more effective, even somewhat less, is even more futile and does nothing. That is, just to say that Samsung has its own Siri, and that’s all.

Galaxy S III is equipped with the latest in family Exynos. How is this processor quad heart “home” clocked at 1.4 GHz compete Qualcomm, NVIDIA and ST Ericsson? To find out, we conducted all our usual benchmarks. Start with the processor …

Linpack

Linpack is a benchmark that evaluates the power of the processor. The result is expressed in millions of floating point operations per second (MFLOPS). Compared to Benchmark Pi, the main advantage lies in the possibility to test multi threaded (multi-core processor so).

The single and multi threaded tests remain largely dominated by S. HTC One The dual-core SoC Snapdragon S4 Krait (1.5 GHz) Qualcomm does wonders managing to hold a candle to the quad-core Exynos 4412 (1.4 GHz, Galaxy S III) and Tegra 3 (1.5 GHz, HTC One X).

Multi threaded, the Galaxy S III ascended still the second step of the podium almost tied with the iPhone 4S (A5 SoC, double heart 800 MHz).

SunSpider

Web site with SunSpider, the authors of the benchmark JavaScript HTML rendering engine Webkit (Safari, Chrome …). Galaxy S III lets talk powder by winning the high score ranking. Good results are confirmed by practice. Surfing is perfectly smooth in all circumstances.

GL Benchmark (Off Screen)

GL Benchmark evaluates the performance of the graphics terminal. Offscreen test is independent of the resolution. Here, the Galaxy S III again won the race, ahead clearly HTC One X and other iPhone 4S.

Autonomy

The Galaxy S III has a 2100 mAh battery, which is supposed to guarantee a good autonomy despite intensive components. And it is true in practice: on our test autonomy in use, it ranks third position behind the Huawei Honor and the Motorola Motoluxe, two smartphones much more modest. It is also better than its closest competitor, the HTC One X, which is still much better than leaving the road.

Photo / Video: the software part

Before detailing the performance of the Galaxy S III pictures and videos, make a turn on the software, which is always full. Among the many options available, it will benefit from a timer, some scenes (sunset, sport, indoor, fireworks …), a burst mode, an HDR mode, the settings of parameters such that the exposure or sensitivity, scenes, macro mode, and some gadgets like smile detection.

Performance picture

No 12 MP for Galaxy S III, then, but that does not mean, however, that the photo and video sensor is recessed. Let us recall briefly the characteristics of the sensor back that we used in our tests: it is rétroexposé, which provides better sensitivity even in difficult lighting condtions, and goes up to 8MP photo.

Speak now practice. Very simply, the Galaxy S III displays excellent image quality, among the best we have ever seen on a smartphone.

It begins with our test scene, which allows us to immediately note two characteristics of the lens. Firstly, the very high accuracy of the images produced: one can quibble around the edges a little less well defined, but it is the case of all sensors of smartphones, and the gap is far be obvious. We also note the side very flattering colors and contrasts: it is certainly a little less saturated than it looks on the Super AMOLED screen of the mobile, but the images are a bit more “flashy” than in the real life.

The exterior is also an opportunity to test the rendering device in HDR mode, and again, we are amazed: the responsiveness of the device, apparently supported by the processor quad-heart is so remarkable that it took several shots to inspect realize he took out two different views.

Conclusion

A year after the release of the Inspiron 1720 Battery , which probably remained, until very recently, the best Android Smartphone available, his successor he managed the handover? Certainly, yes! The qualities of the Galaxy S III are numerous, and so we will start with what leaves us cold, namely the design and finish. Of course, once in hand, the Galaxy S III is much less “cheap” it looks on paper. The design is not the most original, even if you feel that Samsung has at least made an effort to move away from the lines of its predecessor, but on a smartphone sold over 600 euros, we still expected a little more luxurious than glossy plastic shell with a metal rim in imitation.

Fortunately, Samsung catches up with a few surprises of his choice: the phone is almost as light and thin as the Galaxy S II, while a portion of smartphone users will appreciate the presence necessarily a removable battery and a Micro SD slot. In addition, if your back is weak, the facade Gorilla Glass 2 is excellent. However, it really reached the limits of use in terms of size: despite the undeniable comfort of the 4.8-inch screen, we meet as the Galaxy Nexus or HTC One X situations or use a hand is uncomfortable, especially for Dell XPS M2010 users with smaller hands.

One could also criticize some software additions that do nothing, as S-Voice, a botched clone of Siri that is not better than his model, though not very brilliant, and that is even worse. In the end, the functionality will only give grist to critics that Samsung will surely ironic about the plagiarism.

So what we have to blame the new flagship of Samsung. Else is simply the best of what we can expect from a smartphone in 2012. The processor quad-heart Exynos 4412 Quad explodes almost all its competitors, with the exception of S HTC One on some tests. The graphical part is not left: Mali 400 MP4 obtains excellent results. Regarding performance photo and video, the Galaxy S III is faultless: the images produced are accurate, the camera is a perfect response, especially with regard to gusts and HDR videos are fluid, responsive development … We look good, there is nothing to complain about Dell Inspiron 1721 Battery!

With a 4.8-inch screen (1280×720 pixels) and a quad-heart, one might have feared for the autonomy of the smartphone, but again Samsung ensures: 2100 mAh battery there is probably not unrelated.

Finally, the software has not been neglected: the photosensitive layer is rich in features, video player, DivX Certified, swallows all videos that he has provided, regardless of the format and definition, and audio player provides the essential (equalizer, enhancing effects and spatial …). The overlay software is in sobriety: Samsung has adapted its Touchwiz interface conventions of Ice Cream Sandwich, with which he nevertheless takes large liberties, and provides an interface that is both simple and enjoyable, even if purists regret the disappearance part of “true” ICS.

In the end, the Studio 1535 Battery appears in fact in line with expectations, but certainly below fantasies that buzz before its launch had been generated. It is, finally, a product Samsung’s invoice is classic, but its performance is impeccable, and its full functionality. Its size XXL will not suit everyone, but the smartphone will satisfy those for whom it is not fatal.

XPS M1530 delivers its up to date with the latest components, such as processors Sandy Bridge series. This 15.6-inch laptop will attempt to give life to multimedia content through a graphical map of the highest caliber.

Ergonomics complete

If the master password is dressing “plastic”, the XPS still retains a sleek design. Note, however, the level of finish can be improved since the shell which surrounds the keyboard is pressed at the slightest pressure. This is a little awkward to use, but we expected a little better.

The chiclet keyboard has keys. They are well proportioned and well placed. Typing is smooth and quiet. Usage is pleasant despite the ubiquitous plastic.

The large multitouch touchpad gave us a good impression. The slide is nice and large can browse all the diagonal but not to try several times. Dell was able to optimize the available space on the wrist, which is rare.

Webcam (720p) provides a correct rendering when the room is well lit. Dark areas do not form black holes, the return movement is correct. When the room darkens the webcam just a little, but manages to maintain a level of detail that many models envy him.

Distributed over all the slices, the connection is complete. At the front is the SD card reader. At the rear, the Dell Latitude E5500 Battery power supply, the video outputs (HDMI and Display Port), Ethernet port (RJ45) and a USB 3.0 port. On the left, a second USB 3.0 port, and finally on the right port combo eSATA / USB 2.0, audio connectivity and a Blu-ray.

Side heat dissipation, the XPS 15 comes out honorably limiting the temperature rise to acceptable values. However, once it is pushed, even slightly, it goes in decibels and is very present.

Calculations: good performance

The XPS M1330 received in our lab features a Intel Core i5-2410M, a powerful processor that we have already had occasion to cross. It is therefore no surprise that allows this 15.6-inch practice without forcing usual activities (office, internet browsing, etc.).. It is also perfectly at ease with the most demanding activities. Video encoding, 3D modeling, image editing, he can do anything in a timely manner.

Video playback in high definition (HD 1080p Blu-Ray equivalent) passes smoothly on this computer. So you can use the Blu-Ray player without fear of stuttering and enjoy movies in high definition.

The start of Windows 7 Home Premium 64-bit is in 47 seconds. It then takes between 5 and 10 seconds for the launch of various software and connecting to a wireless network complete extinction takes less than 30 seconds.

Games: building honest

The capabilities of the GT 540M XPS 15 can operate in all games, old and new, in the native resolution of the screen (1920 x 1080 pixels). Some require intensive games however make some concessions on the level of graphic detail.

With FIFA 2011, Left 4 Dead, or The Sims 3, no problem, we push all the settings back. With heavy, like Metro 2033, so do not expect to exceed the “low” level of detail. Between the two, there are titles like Dirt 3 or “average” is supported. In short, the hardcore gamers will find probably a bit limited, but for casual gamers, the XPS 15 will do the trick.

Audio: good … and less good

Good start for this computer, the audio system JBL works great. The sound output from the speakers is among the cleanest heard on a laptop, with the power to control, and sound mastered without vibrations.

Side I / O against, the situation is much more mixed. Line output is very bad so much the worse for the speaker kit. Both inputs are downright mean, the headphone output barely drinkable but at least usable. Too bad it was a good start.

Nearly 4 hours of battery life for the walk … at home.

Thanks to the presence of NVIDIA Optimus technology – a function that provides power to the graphics card only when the capacity of chispet graphics (Intel HD 3000) are exceeded – the Inspiron 1300 enjoys autonomy 3:50 video playback (headphones connected, Wi-Fi off and screen at 100 cd / m²). But his tightly packed 3Kg do not make a good companion not ride. Better therefore confined to domestic use.

The slab XPS 15 is unfortunately brilliant. Outdoors, avoid direct sunlight to reduce glare.

Its 15.6-inch diagonal displays a resolution of 1920 x 1080 points. The characters are a good size and not cause excessive eyestrain.

The technology used is TN, with a persistence time equivalent to 5 ms models. As a result, viewing angles up and down are short and sufficient reactivity for office use and for movies. It’s a shame for a machine oriented games, but this is unfortunately very common.

The default colors are false, with a difference (deltaE) of 10.1 and a slight drift of the blue color. The contrast is not very bright – although higher that offers a large majority of laptops now – with a rate of 650:1. We measured a black level of 0.41 cd / m², a white 264 cd / m².

If our color profile, available on Digital Focus is always there to correct those ugly colors, it can do nothing for contrast.

In the family of Macbook Pro 2011, here is the 13.3 inches. Is a diagonal or Apple is already present via its 13.3-inch Macbook Air. If he can play on the size or weight to compete, it is the power of its components that will allow or not to get a place in the market.

Ergonomics: a beautiful product that lacks some connections.

No major design change since the 2010 series. Always clean and simple, it immediately gives an impression of quality. This is confirmed by the choice of aluminum as a material for the frame. Her hull “unibody” (one block) does not crack and can support anywhere without it sinking of a millimeter.

The keypad separate or chiclet is backlit (can be disabled to preserve battery life). The keys offer a flexible and extremely quiet typing. Their good positioning to type text so instinctive. Fun for word processing.

The PA3534U-1BRS touchpad is always what is best on the market. Multi-touch (zoom, rotate, scroll several fingers, etc.)., Large and clickable, it offers slides very smooth, comfortable and accurate. Enable “Tap to Click” in “System Preferences”, it can not have to press the touchpad to click. This avoids noise and long click, we gain a certain time.

Webcam (1280 x 720 pixels) offers a quality rendering. The exposure is correct, as the return movement. In bright areas, the image is detailed. In dark areas, as for many models, you lose detail. It remains perfectly suited to everyday use.

The connection is, however, not well developed. On the right is the reader / writer type “snap disc” or slot-in. On the left, the power jack, an RJ45 port, a Firewire 800 port, two USB 2.0 ports, SDXC card reader and finally a Thunderbolt port.

For the record, Thunderbolt is the name of the new connection to high-speed integrated by Apple. From Intel, it mixes with the DisplayPort connector technology Light Peak. In the line of FireWire, this connection “to do everything” can chain up to six devices of all kinds, including those dedicated to video. Backward compatibility with DisplayPort is ensured as the screen is the last link in the chain. Without compatible device to the editor we have, for the moment, unable to test its performance in terms of throughput and display. We will fill this gap as soon as possible.

Perfectly silent at startup, the Macbook Pro 13.3 inch surprised us during the evaluation tests the processor. During this period which imposes different types of tasks rather heavy for the processor, the sound of the fan is mounted to blow down a few minutes later. It is quite unusual for a model in this range normally considered silent.

In contrast, the rise in temperature is low, therefore small fan doing its job. We would still enjoyed it does so more quietly …

Calculations: excellent performance

With the received configuration, the HP Pavilion DV6 is capable of doing almost anything in a reasonable time. It is effective both in encoding video photo montage. Office, internet browsing and other tasks just crunching it does pose a problem. Its index is 130 processor.

Video playback in HD 1080p (Blu-Ray equivalent) is a walkover for Macbook Pro 13.3 inch. While this is easily achievable with the CPU alone, it is preferable to leave this task to the graphics chipset (QuickTime handles this automatically). In this way, as the CPU usage, consumption falls thereby maintain maximum independence.

Boot Mac OS X is in 34 seconds. Extinction is, in turn, less than 5 seconds. Excellent time to reflect the general responsiveness of the machine.

Games: a simple integrated graphics chipset

The 13.3-inch model is the only range that is lacking a dedicated graphics card. Instead, he must be content chipset Intel GMA HD 3000. It proves able to run recent games like Starcraft 2 or Call of Duty Modern Warfare 2 with graphic details to a minimum. Not a fan’s dream game …

Audio: always clean

On the audio side, nothing happens at Apple, but at the same time, how blame them? With speakers slipped under the keyboard, the manufacturer can do better than 95% of laptops today. Not to saturate the HP have a very comfortable margin of power. The headphone output is always clean. Damage the input line has disappeared, rappatriée on the same connector as the headphone output. Not practical. Fortunately, the microphone works well.

Autonomy: 8h away from the socket!

While Apple provided 7 hours on all models of generation Macbook Pro 2011, 13.3-inch withstood eight hours of video playback. An excellent time, considering that the Macbook Air 13.3 inch – less powerful and therefore, normally less greedy – took less than 6 hours under the same conditions (video playback, headphones plugged in, screen at 100 cd / m², Wi-Fi and Bluetooth off).

More autonomous than the Macbook Air 13.3, it is also heavier (2.04 kg against 1.32) is more cumbersome. Its dimensions and weight are, however, sufficiently low to allow transport backpack without worrying about the state of his back.

The slab is unfortunately glossy Macbook Pro. From the Apple site, it is impossible to choose a mate on the diagonal slab.

With this Compaq Presario V2000 screen size, it would have been nice to find a resolution of 1366 x 768 pixels, as is the case for many of the 13.3 inches. As it stands, its 1280 x 800 pixels can still offer a number of displayable information correct and respectable character sizes.The technology used is TN, with a persistence time equivalent to 5 ms models.As presented in a brief, its slab (reference 9CC3) is a higher quality than those located in general laptops.

Despite the drift color blue, the colors are correct throughout with a difference (Delta E) of 2.9. The contrast is just right – rate 650:1 – but still higher than many models often below 300: 1. We measured a black level of 0.30 cd / m², white at 200 cd / m².

During the summer, Dell Latitude E6400 renewed its professional range with the “E” series. There are many improvements over the previous generation including a completely new chassis advertised as particularly rigid and features – often optional – who are upgrading from the competition. The Latitude E can thus receive a screen with LED backlight brightness sensor, a backlit keyboard, HSDPA modem, etc.. At the technological level, the range is of course based on the platform “Centrino 2″ and Dell announced a range quite impressive despite the presence of an NVIDIA Quadro NVS 160m. There are so many things to check with our Dell Latitude D620 Battery premium …

New look

Black and angular, the new Latitude E etrennent what Dell calls the “Industrial Design”. Fans of the famous Thinkpad will not be disoriented! Even large silver hinges with beveled corners are clearly inspired by the design of Big Blue … The double scoring system is still present but the trackpoint inherits a third button, once again, just like the Thinkpad! With the range Dell Latitude D630 Battery, Dell attack so clearly its competitor always in the workplace.

From the first minutes of the grip, the Latitude E6400 mark a clear break with the previous generation (eg D620): Exit plastics painted and moderately stiff. The Dell Latitude E4200 Battery inspires quality and rigidity. In fact, it does not inspire: it’s solid! The opening screen is a central button that leaves an impression somewhat mixed. But the hinges are exemplary. They are firm and wish to hold the screen perfectly in place. No game to lament, not the slightest oscillation of the screen and they keep strictly slab regardless of angle (limited to 160 °).

New chassis!

For information, the first portable Dell Latitude E5400 consumer prices and use a simple plastic shell and ribs provide rigidity … The only metal parts are usually hinges. The Latitude older generation used a frame “device” called “tri-metal”. A name for a highly technical architecture actually quite commonplace now used by mobile phones mid-range … With the Latitude E line, Dell has inspired once more Lenovo to introduce a structure similar to the “Roll Cage” aboard the Thinkpad. The Dell Latitude E5420 motherboard and thus the hinges are grafted on a single piece of metal that provides rigidity copy. Unlike the “Roll Cage” Thinkpad (magnesium structure and outer shell internal plastic), the chassis of the new Latitudes E is “internal and external”. Clearly, some parts of the structure are also involved in the hull and the cell line (especially the back where the hinges attach). In the absence of truly innovate, Dell turn uses a technique very accomplished. Note that Dell and Lenovo are not yet in a totally one-piece chassis as the “Unibody” introduced by Apple with the latest Macbook and Macbook Pro (well ahead of the  Dell Latitude E5500 PC world) …

Under the laptop Dell Studio XPS 13, no question multiple access doors to the various components. A large metal plate “closes” the chassis. Must loosen 3 screws (2 for the hard disk and one for the cover itself) to access the internal components but the rigidity wins as the overall accessibility … You can also highlight the hard drive easily accessible: we do there are only three screws to unscrew to change disc (2 brackets and 1 for “caddy”)! In this idyllic picture, however, we note two caveats. The Dell Studio XPS 1647 hard drive is screwed directly to the chassis (no vibration system like the Thinkpad or Macbook Pro). Mechanical noise therefore tend to be magnified. Fortunately, this is only half evil insofar recent discs (same performance) are quite discreet. The second point “low” is metal against metal contact between the frame and the bottom cover. Despite a good fit and suitable tightening screws, frame issues sometimes “clong clong” fairly typical uninviting. Say they sabotage the perception of strength, they serve the intrinsic quality of the chassis … Simple “pad” easily eliminate these noises …

It turns?

For many of our readers, silent operation, especially in office is an important if not crucial in choosing a laptop. The Latitude E5500 we tested a model with a Core 2 Duo P9500 (2.53 GHz Penryn FSB 1066 MHz 6 MB cache) and a Quadro NVS 160m 256MB (580 MHz for the core and 16 stream processors at 1450 MHz), a configuration quite muscular for a 14 inch. Despite this power (albeit modest in 3D), the ventilation is triggered only rarely in office. As any fan PWM, starting a diet requires a little high but the speed drops very rapidly. The noise at cruising speed is weak and annoying (breath). Another important point, the fan stops almost immediately after a request from the processor and / or chipset. Only 3D games activate the fan at full power and it becomes audible. Last detail: Notebook heaters generally little … In the end, the Seagate Momentus 7200.3 250 GB is usually the largest source of noise. With an SSD, the Dell Latitude E5520 is a charm!

Pamper the user …

The Dell Latitude E6220 does not simply align the technological qualities. The backlit keyboard – Macbook copied – is one of the best we have encountered. Keys (smooth) are really nice to the touch, is exemplary firmness, running is good and it is quiet. Personally, I prefer even a “ICES” Thinkpad (note: NMB is the subcontractor that produces the “best keyboard IBM”). The Dell Inspiron 1520 lighting is controlled and may turn off automatically when the keyboard is not used or left on. Attention, the backlight option is charged € ~ 50 …

Without Trackpoint match the IBM scoring system “to stick” is correct. I must say that the addition of the third button is for many … However, the “cap” is quite small, rather poorly done, too soft and it does not provide as good a grip as the Thinkpad. In addition, it does not exceed enough buttons … Do not worry, it is quite feasible! The Dell Latitude E6320 touchpad recognizes movements of zoom and scroll “round and round” (like Samsung). Unfortunately, it does not autoscroll continuous or programmable zone and is not multitouch … Small detail, the palm rest is also metal … But unfortunately, like all metal parts of the Latitude E6400, it retains all traces fingers!

1440×900 screen with LED backlight is excellent. With the brightness set to 5 or 6, it competes with a TFT with a conventional neon. Maximum (level 15), the Dell Latitude E6420 screen is too bright for indoor use. Given the current weather conditions, it is difficult to estimate readability outdoors but without going too far, it should also be good. In the evening, a backlight set to 2, 3 or 4 is more than enough. A light sensor can dynamically adjust the backlight, which increases the autonomy … The angles are in the middle, without more, while color rendering is downright good and the backlight is uniform. Sump screen defends pretty well especially for a side stiffness model also end.

Multimedia, communication and connection

The Dell Latitude E6520 is equipped with a webcam, a microphone and a pair of speakers. If the first two do their job, the “speakers” are poor with his metal too. One would wonder if most Windows sounds were not changed until the record is different … Fortunately, the headphone jack does not suffer from this defect! The memory card reader is mounted on the front type SDHC but it did not recognize all SDHC test. Finally, the good old analog VGA port is supported by a digital DisplayPort.

Communication side, our Dell Latitude E6510 top model provides: Intel Wifi Link 5300 AGN Intel 82567 Gigabit V92 modem, Bluetooth and HSPA EDR (Broadcom). ESATA and FireWire complete the package. Infrared goes out the window … One ExpressCard slot and a docking connection can extend the capabilities of the machine.

Small details …

Dell Inspiron E1405 Battery has apparently treated its Latitude line E in detail. Thus, the power outlet is located at the rear as well as RJ11 and RJ45. The four USB ports are located on both sides of the laptop. Left or right handed, no cables will be penalized by adding an external mouse … Note that the lower left USB port is combined USB and eSATA! And yes, you might as well connect a USB device as a hard drive eSATA. Frankly practice! Usually placed in the wrist rests, the biometric reader is here next to the keyboard, as the speaker. This is more convenient when the laptop is used on the knees (provided they are handed) … In this type of application, we also appreciate the completely flat and smooth bottom of the laptop Dell Inspiron E1505.

The lights are blue including the webcam and the LED placed into the supply side laptop. The marriage of blue and black is a success story that gives the Latitude E a compromise between “restraint professional” and trendy design … Dell has not yielded to the latest fashion of placing areas tactile volume control or multimedia features. To assist the keyboard, the Dell Inspiron E1705 Battery relies on three buttons increase and decrease the volume and mute. Simple, clean, functional and unadorned: they love …

Mobility

The Dell Inspiron Mini 10 is a laptop 14 inches wide. It displays 2495 grams on the scale with high battery capacity of 85 Wh. As on Thinkpad T40p since it exceeds the back of the laptop. If the Latitude E6400 is one of the smaller models with 335 x 244 x 33 mm, do not forget to add 20 mm in depth for the battery “beyond” … The adapter is quite large (145 x 70 mm ) but very flat (16 mm), which facilitates the storage. And nothing to spoil, Dell Inspiron 13R is equipped with a two-pin plug (without unnecessary grounding). Side weight, it is a good average with 400 grams including cables. However, you will not have to wrestle you all day long because the autonomy of up to 6 hours with WiFi active and backlight controlled by the light sensor. With the backlight set to 50%, it is still 5 ½ hours under the same conditions … A perfect laptop for all mobile!

We can also note that the chipset Intel PM45 (Cantiga) enjoys a 65nm (although it is still ICH9m 130 nm) against 90 nm for PM965 machines Santa Rosa, which is beneficial for autonomy.

Dell Inspiron 1200 Last detail related to mobility, modular bay that contains a DVD burner Matshita here UJ862A is now 9.5 mm high (like the Thinkpad T Series) against 12.5 mm before. That would produce chassis as thin as competitors but in return, Dell no longer offers optional battery bay. It must pass through the battery slice that enhances the laptop quite significantly.

Performance

Dell Inspiron 1300 With a Core 2 Duo P9500, a Seagate Momentus 7200.3 and 4 GB of DDR2-800, this machine is swift frankly, whatever work to do. By cons, do not expect anything in 3D graphics chip as the Quadro NVS 160m. It is not more powerful than the Quadro NVS 140 that the Thinkpad R61 team tested last year … It does also not better than the FireGL V5000 and Radeon X1600 in T60 and T60p from 2006. Many opt for a model equipped with a GM45 PM45 instead of torque and Quadro NVS 140m. Without using the optional battery of 85 Wh, autonomy should be of the same ilk.

Dell Vostro 1520 here is not much to report about the performance but about the DVD compression. Indeed, the Latitude E6400 request almost a minute longer than the Thinkpad T61p with a less powerful processor. Curiously, the CPU load fell regularly for no logical reason.

Momentus, Digitus USB 2.0

We took advantage of the presence of the Dell Inspiron 14R eSATA port to test the Seagate Momentus 7200.3 250GB of origin in the internal bay and via eSATA and USB 2.0 via adapter Digitus and through a housing IcyBox. Connected via eSATA, the drive is as fast as in its internal bay (which is normal). Note that to take advantage of the “hot plug” eSATA, ICH must be configured in AHCI. Mode or IDE compatible, connect the disk causes system hang … Between USB and eSATA, the average transfer rate from 17 Mb / s to 72 MB / s. Sans comment! In these tests, we installed the system on a OCZ Core who is unfortunately clamped at ~ 110 MB / s read. In contrast, the Dell Inspiron 1464 Intel X25-m fully expressed!

Conclusion

With its range E Inspiron 1545 Battery, Dell introduced a new chassis that combines highly effective stiffness and accessibility. The change is also reflected in a change of look and the transition to the Industrial Design clearly developed to attract fans Thinkpad. The Latitude E6400 that we tested is equipped with the most powerful components for a 14 inch wide but it does not heat and fan noise never run more than necessary. High performance, the Toshiba pa3817u-1brs is also a reference in terms of autonomy: up to 6 hours battery with 85 Wh. To avoid spoiling anything, the keyboard and dual pointing are really perfect. They easily seduce any unconditional Thinkpad! Especially with the keyboard backlight option that matches the comfort of Thinklight. Still on the strengths, 1440×900 LED screen (optional) controlled by a light sensor is really a must. Default side, we can pin some noise associated with metal against metal chassis and enclosures poor. In the current offering, the Dell Inspiron 6400 is a laptop that we recommend …

Dell XPS M1530: 9.5 / 10

To: Rigid frame, design, finishes, hot little ventilation rarely active and quiet 6:00 85 Wh battery (optional) LED 1440×900 screen (optional), backlit keyboard (optional), 4 USB ports including a combined eSATA , DisplayPort, very good keyboard, trackpoint, 3 buttons, except leading performance …

Cons: … 3D pregnant poor, many options, noise chassis bit programmable touchpad, trackpoint cap of poor quality.

1-How to save battery?

Once your laptop Inspiron 1545 Battery fully charged, it is necessary to know to maximize its autonomy does not melt like snow in the sun. It should then observe a few rules that minimize energy consumption. To begin with, it is interesting to identify the components or uses the most electricity intensive. The processor, in full activity, in part.

Fortunately, Dell Battery manufacturers have made significant progress in this area. Chips only consume energy when they are requested. Therefore it is better to know what is energy consumer and what is not. The record for the biggestInspiron E1505 Battery eater comes to integrated graphics chipsets on the motherboard.

Attention to games and movies on DVD!

If you want to prolong the Latitude D630 Battery, it is best not to run parts of video games: wait to be connected to the mains! Similarly, using the player or recorder to watch a movie may begin considerably the life of your PC. It is better to encode DivX movies and store them on the hard drive, much less greedy.

Disable Wi-Fi if you do not use.

To optimize the Pavilion DV6000 Battery life, we also recommend you disable controllers Wi-Fi and Bluetooth, so you do not need it, down a bit the brightness of the screen and especially to avoid use of self-powered external devices (USB sticks, hard drives, mice …).

The right settings increase the autonomy

Compaq Presario CQ60 Operating systems Windows XP and Vista offer a menu of power management. Right-click on the desktop, drag Custom (Properties for XP) to reach the Screen Saver tab. Then select Power Management (Change power settings for Vista) to access the methods of power management. This window is the actual control panel power consumption of your computer. Both operating systems Microsoft offers pre-programmed modes for power management. You can choose the one that best fits the use you want to make your COMPAQ PRESARIO CQ61 Battery.

a-To maximize the HP Battery, use the Minimal Power Management Mode for Windows XP and Vista for energy savings. These options determine the waiting time before the monitor from turning, stopping or hard drives, simple and standby time, that your microphone is connected to the mains or battery.

b-It is also possible to create your own mode of Pavilion DV6 Battery power management, customizing each field of action. To save your new settings with XP, you must click Save As and give them a name. Vista users must, in turn, select Create mode power management, name and change the settings according to their convenience. In both cases, your new mode will then appear in the list.

2-How to maintain the battery

Who wants to travel far (and long) steady wins the race! The Inspiron 6400 Battery is the heart of your laptop. It is therefore to take care and maintain information so that it lasts as long as possible.

Should completely drain the battery?

It is very common to hear about the importance, during the first charging time to completely empty the Dell Inspiron 15R Battery before this operation, eventually allowing it to survive longer. This is wrong! Rather careful not to fall below the threshold of 5% load. Too low a level of support can greatly damage the electrical system and batteries for your battery.

Charge cycles

In the early days, it is recommended to impose your Studio 1555 Battery full charge cycles. Its level down to 5% and the maximum load without interruption. This is the calibration. It allows you to get the best performance from the battery. This operation is repeated every two months for casual users and each month for regular. Meanwhile, make small steps to recharge, even incomplete. A full recharge cycle corresponds to replenish the XPS M1330 Battery to 100%. You can do it in one sitting or in spurts of microcycles 5 or 10%. Note that a standard battery supports between 500 and 1000 cycles of charge.

Should keep the battery when the computer is connected to the mains?

If you use your laptop mostly on your desktop connected to the outlet, it is best to remove the XPS M1530 Battery. The biggest enemy is heat accumulators. A flat on your workspace, the air circulation is bad, and your laptop gets very hot. It is best to remove the Vostro 1510 Battery and store it in a place away from heat and moisture. Be careful though not to forget to charge it before using your phone outside area! There are also cooling pad, equipped with fans to cool a little computer.

What is its lifetime?

His life depends on the attention he door. A well maintained model can be used between 2 and 3 years. But over time and the use you make of it inevitably loses Vostro 1520 Battery capacity. The elements that compose age and wear. However, you can acquire specialized sites a new battery and give a fillip to the autonomy of your laptop.

At the end of 2007, the arrival of a new type of computer invented by Asus fed many topics of conversation. Since its commercialization, the Eee PC 701, the first of a long series of netbooks HP 484170-001 has been successful despite many limitations as an “SSD” only 4 GB, not really suited Celeron M, mini screen 7 inch 800 x 480 only, etc.. The netbook today has very little in common with its predecessor except maybe the price. Overall, it was “gentrified” but not necessarily in the bad sense. To make a point about the age of netbooks, we tested one of the latest Eee PC, Asus 1215B based on the AMD Brazos platform APU Zacate and E-450 …

After 4 years of development …

The Compaq Presario CQ60 arrived in Europe in the first quarter of 2008. This is the first netbook marketed by Asus, the inventor of the concept. The machine is extremely compact 225 x 165 x 30 mm and weighing less than 1 kg To contain the price, Asus Xandros book with this machine installed on a mini SSD 4 GB or 8 GB In the absence of processors Economic dedicated to such small machines, Asus chooses a Celeron M 353 900 MHz sub-clocked to preserve autonomy. Despite an advertised price of $ 299 which turns into € 299 in our countries, the Eee PC 701 is a great success … Just what happened first netbook, the announcement of the Atom, Intel cheap low consumption and new machines for the summer of 2008 just calm the enthusiasm of buyers.

The summer of 2008 has witnessed a veritable tidal wave of netbooks, all brands are being launched into the adventure with models finally “slightly different” 1024 x 600 display, Intel Atom, 160GB hard drive Go, webcam, wifi, and Windows XP. The Asus EEE PC 901 and 1000H, MSI Wind clone and the Medion Akoya Mini and the Acer Aspire One and Samsung NC10 clearly marked that period … The average price of a netbook is then around 350 €.

The year 2009 was marked by the arrival of the Atom Z and its companion chip Poulsbo much less demanding than the old i945GSE (and huge TDP of 12 watts or 5.5 times more than the Atom). Unfortunately, this trend is to the detriment of an already modest power. Machines like the Compaq Presario CQ61 has a nice offer beautiful 11.6 inch HD (1366×768 1024×600 cons) unusual for a netbook, the benefits duo Atom Z520 & Poulsbo make them lose the appeal. Samsung brings some freshness into the landscape with the NC20, a 12-inch 1280×800-based VIA Nano. NVIDIA benefits in September 2009 to offer an alternative to the old chipset i945GSE. Unlike Poulsbo, it is cut for excellent performance including 3D. The ION is experiencing a notable success thanks to Samsung N510 and Compaq 311C. It is only a first end of the year arrives in AMD netbooks with the Athlon L110 & torque Radeon X1270. In 2009, prices vary from € 300 for a 10-inch Atom over € 450 for a machine “ION” with 11.6 inches.

In 2010, Intel cut the grass under the feet of HP Pavilion DV6 NVIDIA by launching the Atom N450. They boarded the controller directly across the northbridge (memory controller and graphics) and do not leave much room to ION especially since it is only one free PCI-Express line for communication with any other GPU … The arrival of this new Atom Dual Core variants and not restart the netbook market. The new Atom remain “soft knee” performance stagnate and Windows 7 is struggling to accommodate this if low power and a 10-inch screen with 1024×600. After a lackluster year in which the news was dominated by the iPad and future tablets competing, only the Asus EEE PC 1215N has been a notable success, but only to a very targeted audience. Models like the MSI Wind 12 with its AMD Neo MV-40 pass even “unnoticed”! The rate gap widened with an access price of around € 250 for a netbook first prize at almost € 500 for a top model as 1215N.

Since then, the market seems to be deliberately killed in the bud by Intel and Microsoft. In 3 years, Intel has not advanced the power of the Atom (excluding Dual Core) and Microsoft imposes limitations actually penalizing with Windows 7 Starter. So many manufacturers simply leave the netbook market …

2011: a new hope!

Since 2009, AMD is working on a “new” concept called Fusion. It aims to integrate a graphics processor (in addition to the memory controller) within the CPU becomes the occasion for an APU (Accelerated Processing Unit). AMD prepares its “Fusion” for three different segments:

Brazos is ultraportables and netbooks.

Sabine target conventional laptops.

Lynx is designed for desktops.

In early 2010, Intel has been against the first to market such a processor with Atom Pineview … AMD does not, however, lower arms and believes in its Fusion project. Unlike Intel, with its ATI graphics division, the Texas firm can integrate graphics chips more advanced than the Intel HD Graphics.

For netbooks, the Brazos platform is segmented into three classes:

Desna APU for Z series: TDP 6 Watts

Ontario APU C Series: 9 Watt TDP

APU Zacate E series for: TDP of 18 Watts

As part of the VGP-BPS9/S 1215B is the variant Zacate APU with E-450, which interests us. It is a Dual Core chip using the new Bobcat architecture (codenamed K14) super scalar type 2 exits such as the Atom. If technological choices are close, however, AMD has less performance sacrificed on the altar of consumption that Intel has done with the Atom.

Bobcat architecture and enjoys running “OOO” (Out Of Order) that lack the Atom and penalized in terms of performance. As a reminder, the processors working in “In-Order” process instructions according to their order of entry (defined by program code) that is not necessarily suitable for the microarchitecture of the processor. Treatment “OOO” which was introduced by the Pentium Pro can reorder instructions to optimize their passage through the pipeline according to the specific architecture of the processor and avoid potential bottlenecks or slowdowns. The Bobcat architecture also uses physical registers (PRF) recently reintroduced especially with Sandy Bridge that help reduce consumption. The pipeline “Bobcat” type is short with only 15 floors. AMD has also integrated virtualization that is not present on the Atom.

Any specifications, the Sony VGP-BPS9/B E-450 is clocked at 1650 MHz based on a system bus 100 MHz. Its frequency varies between 825 MHz and 1650 MHz according to the workload by adjusting the multiplier. It loads 32 KB L1 cache and 512 KB L2 cache per core. Zacate processors as the E-450 are engraved in 40 nm CMOS and occupy 75 mm ². In the case of the Asus 1215B, E-450 BGA-413 is soldered to the motherboard and power supply is 1.35 volts. AMD has apparently never disclosed the number of transistors but estimates put ~ 400 million. As an indication, the 176 million transistors on a 45nm Pineview Atom Dual Core N570 occupy as 87 mm ² (123 million of 66 mm ² single core version).

APU Zacate ship also 128-bit memory controller for single-channel DDR3 shared between the two cores and the GPU. This is also the highlight of APU as it is a Radeon Cedar Family “Evergreen” vect5 with 16 units (80 stream processors), 8 texture units and 4 ROPs. In the case of the SONY VAIO PCG-5K1L, the controller supports DDR3 1333 and Radeon HD 6320 is clocked at 508 MHz with Turbo mode at 600 MHz. Derived from the Radeon HD 5450, it supports DirectX 11, OpenGL 4.1, OpenCL and decoding most video streams MPEG2, H.264, VC1 and Xvid. For their part, the latest Atom merely a GMA 3150 2007 400 MHz limited to support DirectX 9.0c, OpenGL 1.5 and MPEG2 decoding.

The Bobcat APU family are associated with a “chipset” A50M (Hudson-M1) via a PCI-Express 1.1 4x called UMI (2.5 GT / s). The A50M supports 14 USB 2.0 ports, six SATA 6 Gbps ports and HD Audio on 4 channels. Engraved in 65 nm, it has a relatively high TDP of 4.7 watts, which leads the total platform TDP Zacate 22.5 Watts.

Asus Seashell

The Asus A42-V6 uses the chassis Seashell Asus launched in 2009. It is therefore a design quite old and already widely used by other EEE PC Series 12xxYZ. Rather successful in terms of aesthetics, it is against the most closed. Indeed, it allows the change of the memory. Any other operation such as changing hard drive or wireless card goes through a tedious removal of parts to fragile clips and removing a sticker “Warranty Void” … The chassis is rigid SeaShell thanks to a large metal plate under the keyboard and palm rest. It also acts as a heat sink for the APU. A fan ensures the evacuation of the hot air inside outwards. There is, however, no radiator or heatpipe system to remove heat directly from the APU … This is the same maximum load, the 1215B is absolutely no heat. The fan rotates against all the time at very low speed. It’s generally not audible but when he revs it sounds. However, it should seek the APU for the noise of the fan exceeds the Seagate as noisy as winded.

The glossy screen suffers from the characteristic defects of TN LED. Black and burned too bright, which inevitably leads to a poor contrast … HD resolution (1366 x 768) is nice on a 12.1-inch screen. We thus find the same workspace as the majority of 15.6 inches. The hinges hold the screen and well casing plastic brushed aluminum finish provides good rigidity. 0.3 Mpixel webcam is poor and it is not the little touches made by Asus as the shutter to temporarily turn off the camera or the power LED nor the software ergonomics “Made In China”, which corrects the shooting …

The speakers are of the same ilk as the webcam. This is certainly a netbook but with two small speakers facing down under the palm rest, the 1215B is far from the sound, as well as a good old 1000H. In a similar way, the microphone is not in stereo as on former Asus EEE PC 901 EEE PC …

Accessibility boils down to a door giving access to the memory banks …

The keyboard type “Chicklet” is correct for this type of machine with keys spaced 15 mm 3 mm. We appreciate the arrows of the same size as the other keys and dedicated keys: Home, End, Page Up and Page Down. For cons, the gloss plastic around the keyboard is a disaster! It retains all the fingerprints it is difficult to clean between the keys … In addition, there is a gap between the keyboard and the large plate (just below) which ensures rigidity. So, on certain areas, the abutment after the end of travel of the buttons, there is a second stop when the keyboard base comes into contact with the plate. Unpleasant effect spongy assured.

The touchpad is Synapthics against a reference with a multitouch area of ​​85 x 48 mm. The driver is programmable and allows desire to easily switch buttons. These are combined into a single bar. Clicks are frank and discreet, but the material retains once again all fingerprints. This is not the case against the touchpad “drowned” in the wrist rests in brushed aluminum finish.

In addition to the power button, HP Pavilion ZE2000Z has added a double switch to enable / disable wireless connections (WiFi and Bluetooth) and to cycle between modes of energy saving SHE (Super Hybrid Engine). Incidentally, it is simply triple employment given the presence of three operating modes already present in the original Windows 7 and those offered by AMD Vision Engine Control Center.

Black area represents the added battery and Asus clears on its feet photos …

The 1215B is really high ~ 40 mm at the rear as advertised: 296 x 203 x 38 mm.

The chip is a Broadcom 802.11n WiFi 4313GN really inefficient. On our router D-Link DIR-855, it connects to only 72 Mbps max transfer rate of ~ 4 MB / s. On average, rates are only of the order of 2.5 to 2.6 MB / s and it is not an isolated case, many users have found these performances worthy of a “Wireless-N”.

Finally, if there is a strong point for this pin 1215B is its adapter “size pokey” with its mini netbook side connector and a simple two-pole mains side. It is compact and lightweight, short, well designed and designed for mobility. The 1215B is not too heavy: 1516 grams for the netbook and 204 grams for the adapter (or 1720 grams total transport).

Characteristic

Long slit at the hardware level because of Compaq Presario M2200 constraints imposed by Microsoft for Windows XP to take advantage of licenses, the old netbooks had very similar characteristics. In early 2010, the arrival of Windows 7 Starter on netbooks helped increase the capacity of hard drives of 160 GB to 250 GB The latest high-end netbooks were freed from version “Starter” and its limitations. Corollary of these freedoms taken: a netbook like the Eee PC 1215N worth € 499 in September 2010 when it was launched. With 500GB, 2 x 2 GB DDR3-1333 and USB 3.0, 1215B differs widely even more than the price of 349 € is not excessive for a 12 inch HD.

Specifications of netbooks last tested.

Performance

The result of the APU ‘Fusion’ of a CPU and a GPU. It is therefore necessary to examine the performance of the two components, although in the case of a laptop, it is always a good practice to analyze the two parties … We have “dug” in our database to retrieve benchs netbooks significant (ION), representative (Atom N270, N520, N450 and D525) and / or exotic (Via Nano or AMD Neo) to identify the best benefits APU Zacate.

The CPU part of the APU does not offer revolutionary performance in single task. Indeed, with Mark CPU score of 130, the E-450 is only 11% faster than the Atom N450 and only 5.7% more efficient than Atom D525. Other processors rare as Via Nano U225 1.3 GHz and AMD Neo MV-40 respectively do best with 141 (8.5%) and 183 (40.7%). Incidentally, the E-450 is far from a Core 2 Duo SU9600 (1.6 GHz) as the MacBook Air 2010 which gives an index of 228 (75%) …

The E-450 benefits from a strong FPU against mono task. Mark with a score of 7529 FPU, it is placed in second position in the ranking of machines used for the comparison.

GeekBench multitasking is a test that exploits the capabilities of the hardware. In this test, the Via Nano U225 (-44.7%) and other AMD Neo MV-40 (37%) fast single task is now to just over the E-450 because of their design single core. Despite the presence of HyperThreading, the Atom N (single core) are simply dropped (-50% to -63%)! With an impressive index of 1723, the E-450 (Dual Core 1.6GHz) is even better than the Atom D525 (Dual Core 1.8 GHz with hyperthreading) and score of “only” 1394. The APU is also not far from the Core 2 Duo MacBook Air (1816 Windows 7 score significantly worse than under OS X).

Fritz ChessBenchmark is an application that simulates multi-tasking a game of chess. This time, the E-450 APU is exceeded by very few (3.7%) by the Atom D525. All other processors for netbooks are twice as slow … The Core 2 Duo SU9600 is against 28% faster than the E-450.

When transcoding video, the Compaq Presario V2200 offers very good performance. In AVCHD conversion, it is slower than the Atom D525 but it is far more swift against a light encoding format (iPod). The N Atom, Nano U225 and to some extent the Neo MV-40 run in a much lower class … We note in passing that the Core 2 Duo officiating in a higher grade.

Few tests 3D accommodate the low power of a GMA 950 while being representative of the performance of GPU much more recent and swift like ION or AMD Radeon uses. However, make no mistake with the name Radeon HD 6320 relatively “pompous” of the graphical part of the E-450 APU. It offers exceptional graphics performance and support API unusual for an integrated GPU in a processor “modest” but as evidenced by the number of frames per second achieved in “Games / tests” of 3D Mark 2005, gameplay would not go!

HD at minimum: Good results for the APU.

We tested the ASUS A3000 APU and Radeon HD 6320 in games in order to compare with the Intel HD Graphics 3000 Sandy Bridge and GeForce 320m (one of the most powerful IGP) the MacBook Air. The measurements were carried out with all the settings to the minimum HD resolution. The results of the APU are downright good. There is a lack of CPU power in ancient games like Street Fighter IV where a Core ix boosts the score of a Radeon HD 3000. In more complex games in graphics, processor power plays less and the Radeon HD 6320 is no longer behind. Finally, the GeForce 320m is still going strong!

The Seagate Momentus 5400.6 500 GB is a real ball with access time (18.4 ms) and a noise worthy of the last century. Only his transfer rates are correct with a minimum of 41 MB / s and a maximum of almost 82 MB / s for an average of 66.3 MB / s.

After these tests, the performance of the E-450 are “amazing.” We expected a greater difference in raw CPU power compared to an Atom D525 and we expected lower performance 3D/ludiques. In practice, performance recreational and / or 3D that are excellent APU with Radeon HD 6320 that stands up to a Radeon HD 3000 (GPU processor class much higher) but at the processor, the E-450 is not able to compete with an old Core 2 Duo ULV same frequency. In the case of the Eee PC 1215B interests us today is especially hard beating down performance and certainly not the APU.

Consumption, pollution and energy management

At rest, the energy saving profile Windows 7, the HP Pavilion DV4 PC 1215B consumes ~ 7 watts, which is far from extraordinary. In fact, in our tests, the Acer Timeline X 4820TG consumed only 6 watts while idle features a Core i3 330 and a larger screen and equally bright. The Packard Bell TS11, a “15.6 inch” down in turn to 7 watts while the Asus X53SC very similar, can not go under 10 watts. In our tests, the MacBook Air 11.6-inch 2010 is unbeatable only 3.6 watts to display the desktop … The latest netbooks that we tested consumed between 7.5 and 8 watts in the same conditions. According to our usual tests, autonomy is about 5 ½ hours. We expected better from a newer netbook with a battery of 56 Wh …

Playing a Flash video in 1080p (Waka Waka Shakira) in power saving mode application between 12 and 13 watts in both windowed and full screen. The CPU load is of the order of 65%, whereas it does not even use the maximum frequency. There is no loss of image as we leave the machine fully devote himself to reading. To do anything else during playback of this video in 1080p, you must switch to “normal” with a consumption between 13 and 15 watts. These values ​​are comparable to those obtained by HP Pavilion DV5 X53SC and Packard Bell TS11-based Core i3-2310m. The outcome is far from being exceptional …

Prime95, consumption is 18 watts. It rises to 23 watts adding FurMark, giving a range of nearly 2 ½ hours in maximum utilization. With only FurMark, consumption is about 20 ~ 21 watts.

The Asus 1215B is discreet with 33.3 dBA rest. Under these conditions, the hard drive is probably the most audible component. The fan runs all the time makes a noise but low rolling unpleasant middle silencer. When the fan rotates at high speed, the noise level increases to 35 or 36 dBA. Values ​​comparable to those of the last two 15.6 inch we tested with a Core i3-2310 and a GeForce GT 520m … In these conditions, the noise emitted by the fan is “overshadowed” by the air flow ” nicer “to the ear.

The E-450 APU benefits of a variable frequency which is between 825 MHz and 1650 MHz. However, the two cores operating at the same frequency even if one of them is not solicited. The Radeon HD 6320 running at 275 MHz at rest and in 2D. Its frequency climbs to 508 MHz active: 3D and video playback. At rest, the APU is around 50 ° C and the temperature stabilized at 72 ° C after half an hour of Prime95 and FurMark. It should be remembered, however, that there is no heatpipe from the APU fan (which simply extract the hot air from the inside) …

AMD offers Vision Engine Control software which is none other than the Catalyst control panel in its latest incarnation with shortcuts to different energy parameter settings of Windows 7. The utility allows for example to cut Wifi (but not Bluetooth), limiting the maximum frequency of the E-450 1350 MHz or 825 MHz and modify the profile PowerPlay (performance and economy) with different settings if necessary battery and mains (both for CPU GPU), enable questionable Vari-Bright technology (which “washes” a totally made already low contrast), etc.. It offers power management profiles in addition to those already offered by Windows 7 (yet sufficient in our view). To complicate matters, Asus SHE (aka Super Hybrid Engine) also offers profiles … What greatly complicate simple things!

Conclusion

Mink with its platform and particularly Zacate, AMD offers “the” solution that should have existed from the earliest days of the era of netbooks. If the power processor is not significantly higher than the last Atom Dual Core, it is sufficient for Windows 7 and especially in the context of a netbook. The HP Pavilion DV7 Radeon HD 6320 is a blessing for casual gamers and multimedia fans. It is incomparably more powerful than the GMA filthy totally overwhelmed at the support provided by Intel HD streams for netbooks. The Radeon HD 6320 also distance ION “next gen” (too more “next” these days) and can compete with the Intel HD Graphics 3000 and one of the best ever marketed IGP: GeForce 320m.

Unfortunately, AMD is a little late, the market for netbooks being abandoned by the builders … And if the E-450 is enough for a netbook or an ultraportable, it is a bit “feeble” compared to a Core i3 in current laptops first prize. In addition, the TDP of the E-450 is still high with 18 watts which should be added almost 5 watts for the chipset. Certainly, we must use software like Prime95 or Furmark to achieve maximum consumption but 7.5 watts idle and up to 15 watts 1080p Flash playback does not constitute feats: large 15-inch laptop with a Core i3, i5 or i7 are the same “as well” … or better performance per watt Zacate is not exceptional.

In addition to its APU, HP Pavilion DV9000 has strengths as an excellent touchpad, mini adapter with little space taken, good rigidity, port 3.0, 4 GB DDR3-1333, and Windows 7 Home Premium 64-bit . It also has its faults: keyboard spongy place finish gloss around the keys, webcam mediocre speakers very average, low contrast screen with black burnt and no access (except for memory). Finally, € 349 requested help to obscure defects but do not preclude considering models like the HP DM1, the Lenovo IdeaPad S205 or Samsung NP305.

As expected, feels the retina MacBook 15 “light for its size, it weighs 2 kg of even a little less than a 13-inch MacBook Pro. Display and lid are merged into one unit, the only 4 mm thick – this is little more than a beer mat Even the bottom has fallen considerably thinner than its predecessor, because Apple has built no optical drive Overall, the MacBook Pro Retina with 18 millimeters, a millimeter thicker than the MacBook Air at its thickest point…

The new MagSafe Connector 2 is similar at first glance, the very old, only if both connectors side by side, the difference drops to about 1.5 millimeters in height. An adapter that mediates between the old and new power supplies, connectors, are available for 10 euros extra. The USB 3.0 ports, one recognizes the fact that they have four rather than two contacts below. With HDMI and twice Thunderbolt could now connect up to three external monitors, we have not yet tried.

Old and new MagSafe connector.

The reflections of the display, Apple wants to have reduced by 75 percent. In fact, we could see a visible difference to the subjective old 15 “display with a projected screen. The reflections are reduced but certainly not as powerful as the MacBook Air precise statements to be taken only after measurements, which are still pending. In any case, the retinal display is shown with its 220 dpi and 2880 x 1800 pixels on the eye, almost like writing and pictures printed out, just as sharp as on the new iPhone or iPad 4/4S.

With four times the pixel count on the same screen area with no content changes in the system would be represented very small. So Apple has adjusted the display: Menu fonts and images do not appear at one quarter the usual size, but just as great as on a 15-inch display without retina – but twice as sharp. However, only benefit from programs that have been customized by their developers to the high resolution of the display, such as Apple’s supplied and included in OS X. The windows and graphics of unmatched by the system automatically scaled so that will be of any bitmap image point four, which get blurred images. Even writing this is sometimes grainy (more on that). If we compare the same site on display in Safari, and – the non-optimized – Firefox, shows the clear, see video. Experience has shown that many programs are likely in the coming weeks or months can be optimized with Folder Watch is a first in the Mac App Store already appeared before it was clear at all that Apple would introduce the retina MacBook. Twitterrific is also to have been optimized retina in the App Store. Images in Safari to see only the top command, if the website operator providing high resolution, at the moment except what Apple is doing itself a little.

Apple MacBook Pro Retina – slim body, high resolution display.

Mac OS X displays in the system setup screens under “Resolution” now defaults to no Number of pixels for the screen resolution to more, but only the description “Optimized for retinal display”. If you click on “Scaled”, you can select from four different variants of “Bigger Text” to “more space” that affect the size of fonts and graphics. With “more space” OS X brings a factor of 1.5 smaller, so more content onto the screen. The representation then corresponds in size to that of a 15-inch screen with 1920 × 1200 pixels. When set to “more space” font looked in Safari still look better than in Chrome or Firefox, although the differences were smaller. We could easily procrastinate in both settings window between the internal and external monitor a conventional back and without the variables seemed unnatural.

In the System Preferences screen no longer appears on the native pixel count, but “looks like”.

In theory, the adjustment is to the high resolution screen like the iPhone and iPad. Cocoa-text elements are automatically converted to create bitmaps, the program’s author in double precision, and place in the project and also customize the icons a little if he wants to do it right. Firefox and Chrome do not have that in their writings provide a sharp test could be because the developers of multi-platform projects are not using the right or no Cocoa routines for font, but their own. The lightgun us Cocoa applications and Amadeus Lite DVD2One example, did it correctly, the sails of their writings appeared sharp.

[Update 16:40 clock: Google is working on an optimization of the browser - a new Chrome developer version now supports the retina display of the MacBook Pro.]

The more a program of Cocoa routines and different specifications of Apple’s past makes, the more work the developer has to adapt. He may have to write almost all the new app. In Photoshop, the adaptation also seems to be more expensive. Here not only titles and buttons in menus look pixelated, but also the images to be processed.

Carbon apps like HeliosLANTest principle be scaled up, making their writings get pixelated. For a sharp display, they would have to be completely customized by hand, which is complicated but possible.

Additional hardware and Conclusion

Intel Macs used for the first time in Ivy-bridge architecture allows with its 22-nanometer design smaller chips that consume less energy and therefore produce less heat. The slightly higher clock speeds and improved Turbo Boost certainly make sure that it is transported back to a lot of heat from the case.

Without load, the MacBook Pro retina in a normal office was barely audible warnehmbar. Compute-and graphics-intensive by some special tests, we were able to provoke the fan to blow strongly, however, for example, Dirt 2, Mathematica 8, DVD2one or Cinebench 11th

The CPU-values ​​of the 2.6 GHz model with Cinebench 11 fell slightly better than a MacBook Pro 15 “2.4 GHz, the previous generation, the OpenGL contrast, results are slightly worse. Perhaps the drivers for the new Nvidia graphics GeForce GT 650M optimized still not finished.

The boot time of the MacBook Pro Retina is at 17 seconds for a MacBook Air, this is mainly due to the account of the fast SSD, which is connected with 6 Gigabit (SATA 6G, more “Mac-Turbo SSD” in Mac & i Issue 6). The memory of 8 GB in the default configuration is soldered, it can not expand. Optionally, the one we tested model (2.6 GHz, 512-gigabyte SSD) with 16GB of RAM and order. Then it costs € 3100 instead of 2900. The configuration for € 2280 comes with a 2.3 GHz quad-core processor and a 256-gigabyte SSD, 16 GB of RAM, it also costs 200 euros more. The compact SSD modules are indeed ended, but have a different plug contact as the MacBook Air, so that not reuse the existing modules allow blade.

The battery consists of six individual elements which are glued to the housing. The increased from 77.5 to 95 watt-hour capacity results for the power-hungry retinal displays Apple says no to longer Sony VGP-BPS13A/B battery life. In the test at high loads at full brightness, the battery was empty after five and a half hours, were in the previous MacBook Pro is under the same circumstances, 7:20 h 2.0 USB mouse and keyboard worked without problems on the 3.0 jacks. The sound of the built-in stereo speakers was surprisingly good, but of course, free from real bass.

The interfaces of the MacBook Pro Retina.

Summary

Overall, the MacBook Pro generates a strong retinal Do-Do-reflex. The reading on the screen is much more fun. After changing back to a conventional display is one that suddenly blurred and washed out before. Just the combination of compact design with low weight and decent power for a lot of incentive to buy enough – the MacBook is currently at least to have bad, the delivery time from the Apple Store is currently three to four weeks.

More benchmarks, measurements and test results and a comparison with other top EU notebooks will bring 15/12, which appears in two weeks.

Sony VGP-BPS13A/B

HP Pavilion DV6 Laptop Battery

1 – Do not load cycles and complete discharge

Unlike older generation batteries, lithium batteries do not subissement memory effect. Indeed, in the first batteries, when you do not déchargiez the battery completely, the battery capacity permanant decreased with-and to measure. Lithium batteries accept low discharge and recharge cycles. And instead it is better to make small discharge cycles instead of complete cycles. The laboratory test battery Cadex has indeed assessed the length of battery life in smartphones versus depth charging:

100% depth of discharge: 500 discharge cycles

50%: 1500

25%: 2500

10%: 4700

It is better to make “small” refills regularly.

2 – Perform full discharges … sometimes

Despite a recommendation, it is necessary to make full discharges by time. Indeed according to the manufacturer Lenovo, the systems battery gauge is not accurate (for example, they can shut down the system if the load is too low). Discharge and full charge will allow it to “recalibrate” the gauge.

3 – Reduce overheating of the battery

The lifetime of the batteries depends greatly on the temperature. We therefore avoid any overheating conditions such as sun exposure. In particular, it should not clog the vents of the PC (such as by placing the PC on the quilt!) And we will use specific docking stations.

4 – Store batteries in the cold and with a load level of 50%

It is sometimes necessary to store batteries (PC or spare batteries for example). But even without being used, the battery will lose its capacity permanently. The laboratory has evaluated this loss Cadex:

Storage at 0 ° C with a state of charge of 40%: 2% loss per year

Storage at 0 ° C with a charge state of 100%: 6% loss per year

Storage at 40 ° C with a state of charge of 40%: 15% loss per year

Storage at 40 ° C with a charge state of 100%: 35% loss per year

So load your battery to 40% and put it in the fridge!

5 – Set a maximum load to 80%

Laptops that are connected mostly to the mains. The batteries partly include mechanisms to avoid overload. However, it is recommended in the case of PCs connected to the mains often set a maximum load of 80%. IBM software such as power management allow this configuration.

6 – Have a lightweight software environment

Whether you’re on AC or not, it is necessary to properly configure the power management in economy mode. For the software part, we will disable services and devices unnecessary. See our article on best practices for smartphones.

7 – Disconnect the battery .. or not

The disconnection of the battery in the case of a non-nomadic use is discussed. Applying the foregoing principles, we can indeed extend battery life without disconnection. The disconnection may be hazardous in case of power loss for example. See for yourself!

8 – Limit the use not your mobile devices

And the simplest but most effective recommendation is to use your mobile device with partiemonie. One can indeed perhaps his phone off the train and pick up a book on the train rather than facebook?
