Lenovo IdeaPad Yoga 11 Ultrabook

The smaller version of the convertible in the series, the Lenovo IdeaPad Yoga 11, has made it to us just in time before the end of the year. The new concept from the Chinese manufacturer was a highlight at the Consumer Electronics Show 2012 (CES 2012). The patented hinge design allows for 360 degree swiveling of the display. Lenovo themselves describe the Yoga as a multimode PC, which can be either a notebook or a tablet that can be used in an L- or V- shape. This multifunctionality is currently being actively advertised by Lenovo, which begs the question whether Lenovo has managed to bridge the gap between the two device classes without any adverse side effects. Replacement battery for Lenovo IdeaPad G575E

Despite the identical case design, the configurations of the two Yoga notebook/tablet hybrids are significantly different. The IdeaPad Yoga 13 on the one hand has an Intel CPU, runs Windows 8, and has a 13.3 inch display (1600 x 900 pixels). The Lenovo IdeaPad Yoga 11 we have for review meanwhile has an 11.6 inch IPS touchscreen (1366 x 768 pixels), 64 GBs of eMMC memory, 2 GBs of RAM, an Nvidia Tegra 3 quad-core SoC (system on a chip) with an integrated graphics unit, and runs Windows RT.

At a price of 800 Euros our expectations for the device are correspondingly high. Does the Lenovo IdeaPad Yoga 11 combine the advantages of both device classes, or do compromises have to be made? These and other questions will be answered by this review.

At a price of 800 Euros our expectations for the device are correspondingly high. Does the Lenovo IdeaPad Yoga 11 combine the advantages of both device classes, or do compromises have to be made? These and other questions will be answered by this review.

An Ultrabook on the outside, but more of a tablet on the inside. The heart of the Lenovo IdeaPad Yoga 11 is the famous Nvidia Tegra 3 quad-core system on a chip (SoC) with a clock speed of 1.2 GHz. For this reason the device is also not allowed to be called an Ultrabook, since this description is reserved for devices with Intel processors, and all the current Windows RT tablets are fitted with the ARM chip code named Kai-El. Among these are the Microsoft Surface RT, as well as the already reviewed Asus Vivo Tab RT TF600, and the Samsung ATIV Tab for which the review will follow shortly.

Graphics processing is handled by the integrated Nvidia GeForce ULP in the SoC, which is manufactured using the 40 nanometer process. Further features of the convertible include 2 GBs of DDR3L RAM, and 64 GBs of eMMC flash memory of which only 44.7 GBs are available for use though (net: 70 percent). Exchanging these components is not possible, although it is possible to expand the storage capacity relatively inexpensively via the integrated card reader.

The benchmark course is relatively straightforward with Windows RT, since only applications available in the Windows Store can be installed. Following an extended search came disillusionment: None of the popular test tools are available for Windows RT. For this reason our tests were limited to the current browser based benchmarks.

The results achieved with the IdeaPad Yoga 11 confirmed the performance from previous tests completed by Notebookcheck. Mobile Internet Explorer 10 is very weak with Browsermark 2.0 and the current version of the Google V8 benchmark. Merely the Samsung ATIV Smart PC is an exception to this rule with a score of 2000 points with Browsermark 2.0. Otherwise the browsers from Apple and Google take the lead throughout, whereby the difference with both of the benchmarks almost always lies at over 100 percent.

With the JavaScript benchmark Sunspider 0.9.1 Internet Explorer 10 is once again able to contend with its rivals. In this case the smallest score wins, whereby the browser from Microsoft outperforms in this benchmark, followed by the Apple iPad 4 with Safari and the slightly trailing tablets with Google's Chrome browser.

Subjectively the integrated SoC doesn't encounter any problems with the demands set by Windows RT. The system operates extremely smoothly with minimal start times and very responsive control. Ultimately it will be a question of personal preference whether only applications from the Microsoft Store will suffice, which admittedly doesn't provide a very abundant selection.

Power Consumption
The power consumption is especially interesting in the case of this device, since conventional subnotebooks and Ultrabooks generally require more power than tablets with a SoC. During office use our test candidate required between 1.7 and 2.5 watts, which makes it surprisingly frugal compared to other rivals: The contender from Asus needs up to 6.1 watts in this case (difference: 144 percent), while the Google Nexus 10 uses significantly more with 9 watts as the new Android top dog (difference: 260 percent). The Asus Zenbook Prime UX21A Ultrabook meanwhile lies on approximately the same level as the Google tablet (idle with a maximum of 9.6 watts).

We simulated a utilized scenario with the 3D game "Hydro Thunder". At its peak we were able to measure a power consumption of 7.7 watts. As before, the aforementioned devices from Asus and Microsoft leave a lot to be hoped for with up to 11 watts (RT TF600, 43 percent). The Google Nexus 10 with its 9.4 watts is therefore somewhat more economical (difference: 22 percent). The Asus Ultrabook is of course significantly more power hungry than our test candidate with its Intel Core i7-3517U dual-core processor - with a maximum of 34.6 watts this leads to a difference of 349 percent. Fundamentally the Lenovo IdeaPad Yoga 11 provides the same functionality, although the full-fledged operating system and more potent components make the difference.

In order to satiate the convertible a surprisingly potent lithium polymer battery is integrated, which takes up the majority of the available space, and provides a capacity of 42 watt hours. Comparable tablets and Ultrabooks generally provide batteries with between 20 to 35 watt hours, although this does however also depend on the amount of available space. In the case of a tablet for example, the hardware is usually confined to a much smaller area, while in the case of an Ultrabook the cooling system and space for mass storage also have to find some room.

Battery Life
We simulated the reading of a text document on the IdeaPad Yoga 11 with the minimum display brightness and the flight mode enabled. Only after almost 24 hours did the convertible have to be connected back to the mains power in this scenario. Compared to the Asus Vivo Tab RT TF600 the bigger battery certainly makes itself noticeable. With a result of 16 hours this equates to a difference of eight hours in favor of our reviewed device. The Apple MacBook Air 11 Mid 2012 and other comparable configurations meanwhile also weren't able to match this with a battery life of about 10 hours.

The "surfing via WLAN" test represents a practical scenario whereby a website is refreshed every 40 seconds with a display brightness of 150 cd/m², which represents a reduction of the brightness by two notches in the case of the tested candidate. The end result is a good runtime of 12 hours and 30 minutes. Tablets with a smaller battery, as well as an Nvidia Tegra 3 SoC and Windows RT, aren't serious contenders in the discipline with eight to ten hours. The Google Nexus 10 at least comes somewhat closer with 11 hours. Subnotebooks and Ultrabooks merely manage to last for between four and six hours.

Finally we also tested the runtime during playback of a local Full HD video file (H.264, .wmv, 1920 x 1080 pixels). With the maximum display brightness and WLAN enabled the result was 11 hours and 30 minutes. Considering the usual movie length of 120 minutes the represents enough endurance for about 5 movies.

The Lenovo IdeaPad Yoga 11 reignites the renowned idea of a convertible notebook/tablet, and also succeeds in some respects. The stable 360 degree hinges as well as the pleasant case and the extensive battery life, along with the performance of the Nvidia SoC with Windows RT, all combine to provide a positive impression. The stability of the display lid and stability of the closed case are aspects that do raise some concerns though. The dimensions and the weight meanwhile remain within acceptable limits for an 11.6 inch device, although it is somewhat too heavy and clunky as a tablet at length.

The integrated IPS touchscreen with its good characteristics is able to make a convincing impression, although the convertible isn't able to fully win us over as either a notebook or a tablet. For one the operating system and the connectivity, as well as the lack of configuration options, present considerable restrictions; while a backlit keyboard would also have been a welcome feature. For another, other tablets also offer higher resolution screens, integrated UMTS and LTE modules, and a main camera on the back of the device.

All in all the reviewed device represents a new interpretation of the convertible based on current tablet hardware with Microsoft's new Windows RT, but at a price of 800 Euros there are also several alternatives. Regardless of tablet, no tablet, tablet with a keyboard dock, convertible, subnotebook or Ultrabook; the decision still rests with everyone themselves.

Review HP Pavilion g6-1141sg Notebook

Of course, HP shouldn't be left out in Germany's biggest notebook test either, and is at the start with the Pavilion g6. Alike the competition, an Intel Core i5 is installed in the HP notebook. The processor-incorporated graphics solution, Intel HD Graphics 3000, is used as the graphics card. The HP laptop relies more on a plain and serious exterior and tries to tempt the buyer this way. The price of 499 euros also speaks a clear language. We will find out, in collaboration with our reader cum reporter, if HP wanted to make too many cutbacks, or if it has done a good job in this review. Replacement Battery for DELL XPS 15

HP has given the Pavilion g6 a rather basic exterior. It makes a very unobtrusive impression with the anthracite display lid and black base unit. The display lid is made of plastic and has been given a high-gloss finish. This unfortunately makes it prone for fingerprints. Thus, a microfiber cloth should belong to the notebook bag's standard supplies. The display lid's stability isn't particularly high. The lid can be depressed by a few millimeters without much effort. On the other hand, the display hinges have to be noted positively. They have a metal cover and make a very solid impression. Moreover, they are pulled tight enough to keep the display where it belongs. They only couldn't prevent a slight teetering completely. Replacement Battery for Dell Vostro 1510

The anthracite-gray color is found again when the laptop is opened. The gray part of the inside is separated by a black bezel. The design's rise and fall is very much a matter of personal taste. However, the laptop doesn't look too mundane due to the use of both colors. Replacement Battery for ASUS G72GX Charger
The Pavilion g6 doesn't do quite as good a job in our pressure tests. The left wrist-rest could still excel with a very good stability. But the other surfaces yield evidently under selective pressure and even partly emit a creaking noise. Even the keyboard bends slightly during normal typing. You will notice an even more evident yielding when the keys are hit a bit harder on occasion. Replacement Battery for Asus K52F

According to the label, the hard disk, wireless module and RAM can be exchanged via the large cover on the bottom if required.


The Pavilion g6's heart is the Intel Core i5-2410M CPU from the latest Sandy Bridge family. This processor is a dual core model with a base clock of 2.3 GHz each. The processor can also be overclocked dynamically thanks to the improved Turbo Boost 2.0 technology. Either both cores can be overclocked to 2.6 GHz or one single core to 2.9 GHz, depending on the processor's load. Thus, the processor should also be able to supply enough reserves even at performance peaks. Replacement Battery for ASUS Eee PC T91MT
In return, the processor has many energy saving mechanisms that, for example, reduce the processor's clock during low load. Consequently, the notebook's battery life benefits. The processor is a midrange model from Intel's current array and covers a wide range of possible applications. This make it to a good, all-round processor. The processor places itself in the midfield with a TDP of 35 watts, in terms of cooling. Therefore, the Intel Core i5-2410M is also favored for notebooks with a display size of 13-14 inches or more. Replacement Battery for Dell XPS M1330

The Intel HD Graphics 3000 graphics solution is a GPU incorporated in the GPU. It doesn't supply as much performance as, for example, dedicated graphic cards. But it also doesn't use as much energy as a dedicated solution, either. Nevertheless, the new generation of incorporated graphic cards has also made quite a bit of progress. Thus, the Intel HD Graphics 3000 is roughly comparable to the dedicated entry-level graphics card, Nvidia GeForce 310M. It is possible to render older games smoothly with this graphics card and even makes a few newer tracks playable. But only in low details and resolutions. Replacement Battery for Dell XPS M1530

CPU Performance

The program Cinebench is used to assess the processor's performance. Since the Pavilion g6 uses a fairly new processor, the laptop can score quite well in these benchmarks. The Pavilion g6 notebook reaches a score of 4581.0 points in Cinebench R10 Single Rendering (64 bit) and places itself quite far up in our benchmark chart. Thus, the notebook is even within the performance range of the new Intel i7-2630QM or the Intel i7-640M thanks to the new Intel Core i5-2410M. Notebooks, such as the Acer Aspire 5750G-2634G64 (2630QM, GT 540M) with 4589.0 points or the Alienware M14x (2630QM, GT 555M) with 4574.0 points are in the Pavilion's vicinity. As expected, the quad core processors stand out in Cinebench R10 Multi Rendering (64 bit) and the Core i5-2410M processors all gather in the same area. The processor is in the midfield of its like here. The HP Pavilion g6 achieves 9635.0 points here and thus lags slightly behind laptops such as the Fujitsu Lifebook LH531 (2410M, HD Graphics 3000) with 9659.0 points. Replacement Battery for ASUS N50V Charger

System Performance

The HP Pavilion g6 fares as expected from a notebook with an Intel Core i5-2410M processor and Intel HD Graphics 3000 card in the system benchmarks, such as PCMark Vantage or PCMark 7. It doesn't break any records, but isn't the taillight either. The new Core i5 processor's good computing performance recovers a few points again here. The Pavilion g6 could achieve 6066.0 points in the PCMark Vantage benchmark. Thus, the Pavilion g6 is currently the best rated notebook with a combination of Core i5-2410M and Intel HD Graphics 3000. The MSI A6400-Ci507 S (2410M, HD Graphics 3000) with the same processor/graphics combination with 6056.0 points or the newest 13 inch Apple MacBook Pro (2620M, HD Graphics 3000) with 6009.0 are behind the Pavilion g6, for example. Replacement Battery for Dell Inspiron N5010

GPU Performance

The 3DMark benchmarks are used for our 3D graphic tests. We will look at the 3DMark06 a bit closer here. The Pavilion g6 achieves 3651.0 points in 3DMark06. Compared with the top rate of 24671.0 points, which was set up by the Alienware M18x, you quickly notice in which fields the Pavilion g6, with the Intel HD Graphics, moves. Laptops with graphic cards, such as the Mobility Radeon HD 5470 or the Mobility Radeon HD 5145 are found in the Pavilion g6's vicinity. The Pavilion g6 is in the front third compared with other notebooks that are equipped with an Intel HD Graphics 3000. Replacement Battery for Sony VGP-BPS21

A Seagate hard disk with a (gross) capacity of 500 GB works inside the HP Pavilion g6. The 2.5 inch hard disk rotates the built-in magnetic disks with a speed of 5400 rpm. The hard disk doesn't break any records in terms of performance. It rather looses itself in the mass of laptop hard disk with its average transfer rate of 64.2 MB/s. At least the hard disk has good rates in the access rate with 18.8 milliseconds. Nevertheless, the Seagate hard disk can't hold a candle to a 7200 rpm rotating hard disk or even an SSD. Replacement Battery for HP COMPAQ 6830s

Gaming Verdict

The real time strategy game StarCraft 2: Wings of Liberty was used for the gaming test. It is pre-installed on the notebook as a demo within the framework of the Intel TestIT!2011. Therefore, it is logical to use this game to check the gaming suitability right away. Other games and how they perform on the Intel HD Graphics 3000 can be seen in our big gaming performance comparison, "Computer games on laptop graphic cards". Replacement Battery for Asus A42-U46

We don't expect any surprises from the Intel HD Graphics 3000 card in terms of performance to begin with. Thus, the graphics card manages to render the game smoothly with 68 frames per second in low resolutions and details. However, the game starts to stutter with 22 frames per second as soon as the resolution and details are only turned up by a notch. The game already gets unplayable in high settings with 11 frames per second.

The HP Pavilion g6 only has one large heat source, the processor, due to the omission of a dedicated graphics card. Thus the cooling system doesn't have as much to do and the notebook basically stays cooler because the heat is only produced in one place. Replacement Battery for HP ProBook 4510s

As expected, the temperatures aren't a problem in idle (office) mode. The top's surface heats up to a maximum of 27.0 degrees Celsius and is therefore still pleasantly cool. Nor does the wrist-rest get particularly warm with 25.7 degrees Celsius (left) and 24.7 degrees Celsius (right). The touchpad is also innocuous with 24.6 degrees Celsius. The notebook's bottom heats up to a maximum of 28.7 degrees Celsius and is thus cool enough to be placed on the lap for a longer time. Replacement Battery for Sony VGP-BPS13/S

The temperatures clearly increase during load, especially in the vent's area. The top's temperature climbs to a maximum of 39.5 degrees Celsius. This temperature is accomplished in the rear right area above the vent. The wrist-rest and the touchpad only get warmer by a few degrees. The bottom's temperatures partly climb up to 44.9 degrees Celsius. Thus, the surface slowly reaches temperatures where it could get unpleasant to leave the notebook on the lap for a longer time. Replacement Battery for Sony VGP-BPS13/B

We try to push both the hardware as well as the cooling system to the limits in our full load simulation with Prime and Furmark. For this, both programs run simultaneously on the notebook so that the maximum load is created. We record the notebook's temperatures during this and use the program Core Temp to read out the temperatures. The HP Pavilion g6's processor reaches an estimated maximum temperature of 85 degrees Celsius during the test according to Core Temp. This is a good rate, which still is remote from the danger zone. Even the subsequent 3DMark06 benchmark, with 3655.0 points, is very close to our prior result. Thus, a possible performance loss caused by too high temperatures can be excluded during practical use. Replacement Battery for HP ProBook 5310m

The sound system comes from Altec Lansing. But they hardly supply a better sound than a standard notebook sound system as we know from most other laptops. The sound only appears to come across clearer. Nevertheless, the sound system struggles with the same weaknesses as every other notebook sound system: there simply are no basses. The speakers convince in terms of volume. However, they start to distort when they come close to their maximum. Replacement Battery for DELL Vostro 3500

Battery Life

You quickly notice why comparable notebooks last longer with one battery charge when looking at the laptop's consumption. 9.8 watts – 13.7 watts isn't much in idle mode, but the competition manage to do a bit better here. For example, the Packard Bell EasyNote TS 11 is in a range of 6.7 watts – 10.1 watts. The Pavilion g6 again corresponds to the average during load and only consumes as much as notebooks from the competition consume. Replacement Battery for DELL V13

The Pavilion g6 does a good job without an outlet. However, we notice that it could be a bit better, in a direct comparison with other laptops. Nevertheless, the Pavilion g6 doesn't have to hide. It still manages a whole 5 hours and 11 minutes in idle (BatteryEater Reader's test, min brightness, energy saving mode). The battery is still good to go for 3 hours in a somewhat more realistic test with enabled WLAN and Internet surfing. Then again, the battery only lasts for 1 hour and 12 minutes in load (Classic test, max brightness, high performance profile). If you want to fully recharge the battery, the 65 watt power adapter needs 1 hour and 48 minutes. In our opinion, this is adequate for recharging the 6 cell battery. Replacement Battery for Asus A42-M70

By and large, the HP Pavilion g6 doesn't have any major flaws and will present a possible choice for many who are looking for a low-price office notebook. HP has kept the design rather plain and has omitted gimmicks. The workmanship quality is also all right, but could be better. Replacement Battery for Toshiba PA3817U-1BRS

The Pavilion g6 unfortunately slackens a bit in terms of display. But, this is not unusual for this price range. In return, the installed Intel Core i5 processor gives the notebook a good amount of power and equips the device for office routine. The processor's incorporated graphics card fits to an office laptop. It only gives the user little elbow room beyond that, though. Games usually run smoothly in the lowest settings. Replacement Battery for Lenovo Thinkpad R500

Otherwise, we noticed the notebook's temperatures and noise positively. Both are within a pleasant range. In terms of battery life, there are laptops that score a bit better here, also within the Intel TestIT!2011 campaign.

All in all, the HP Pavilion g6 is a capable and, above all, inexpensive office notebook with only minor flaws. Replacement Battery for HP EV06

Our reader and reporter Tobias B. says:
Case: The case is 100% plastic. Merely the hp logo on the lid and the hinge covers are metal. However, the glossy silver metallic surface lets the notebook look attractive. Fingerprints are collected there, but aren't nearly as obvious as on black high-gloss surfaces.

The display lid yields under just light pressure and can be twisted. But there's no need to fear damages. The hinges are annoying. It would have been endurable if the notebook only couldn't be opened with one hand, but it can't even be adjusted single handedly. While we're on the subject, it's not particularly big, but it is enough to work with on the lap. Replacement Battery for Compaq Presario CQ61

The notebook's bottom can only be dented on the maintenance cover and underneath the DVD drive. The stability is acceptable, though. The plastic can only be depressed so much that it creaks on the top, over the drive. Moreover, the drive can be dented, as well. There is a large area above the keyboard, where the plastic can be pressed.

Basically, hp could have done a better job in terms of workmanship. I liked the Asus X53 with a complete aluminum work surface a lot better. 70% Replacement Battery for Dell Vostro 1520 compaq presario cq40 Charger

Input Devices: The g6 doesn't have a chiclet keyboard, which I personally prefer. The keys are fairly large. But that's not surprising because there is a lot of room on 15.6" when a numpad is left out. I can type great on the keyboard.

The F keys standardly have the FN function. So, one finger is enough to adjust volume or display brightness. Keyboard shortcuts, like Alt+F4, work without FN anyway. The WLAN key is a practical thing. There is a small LED that lights up white when WLAN is enabled (by the way, caps lock does too) and red when it's not. Speaking of LEDs – both for power status and hard disk access are on the left. So, you only have to turn your head and the laptop to see them. The layout is like on a normal keyboard (except for DEL, INS, etc). The arrow keys have an unusual layout, though – left and right are oversized and both up and down together are as small as a single key on a normal keyboard, in return. Replacement Battery for HP Pavilion dm1

Now we come to the g6's biggest flaw – the mouse pad. To be honest, if I had to work productively with it for 2 hours, I'd throw this thing out of the window after 30 minutes. It can only be distinguished from the wrist-rest by its corrugated surface. Thus, you occasionally end up with 2 fingers on it during use, which results in zooming or finding the mouse somewhere completely different. The worst thing is scrolling though. Sometimes it works and sometimes it doesn't. Frequently, scrolling successfully with 2 fingers first works after the third attempt. Maybe, I'm just being too stupid, but I never had problems on the X53. Keyboard: 94%, mouse pad: 50% Replacement Battery for Dell Latitude D820

Display and speakers: The display is about as bright as the one in the X53. I find both very bright, but the nbc team's assessments will be more precise. Working outside is therefore quite possible, but not always (typical glossy screen).

The speakers are great for notebook conditions. Because they are pretty loud and located at the front, you can easily fill a room with sound for a presentation, for example. Listening to music isn't anguishing with the comparatively good bass, but you shouldn't expect a hi-fi experience. Display: 85%, loudspeakers: 87% Replacement Battery for ASUS G75V Charger

Miscellaneous: The booting from standby is also worth mentioning. I've never seen that any faster. You haven't even completely opened the lid and the login screen from Windows 7 is there.

The fan's behavior could have been better. The fan ALWAYS runs, but in return doesn't alter its noise in office mode or while watching movies (from the hard disk) and stays quite cool. Replacement Battery for DELL Latitude E6320

Verdict: Overall, I wouldn't give the g6 a purchase recommendation. You can also get an Asus X53 for about 550€. I see its drawbacks only in the additional 300g of weight and the somewhat poorer speakers. The g6 is miles apart from the X53 in terms of workmanship (aluminum!).

Review Asus K75VJ Notebook

Asus want to attract buyers with a Core i7-3610QM CPU, a GeForce GT 635 GPU and a 17-inch display (1,600 x 900 pixels). Given the specs, the device should be appropriate for nearly all fields of application and many user. Our test will show if this is actually true. Acer AS10D73 charger

We will compare the test sample to Lenovo's Ideapad G780 (Core i5-3210M, GeForce GT 630M) and HP's Pavilion g7-2007sg (Core i7-3612QM, Radeon HD 7670M).

We already know appearance, choice of colors and materials from the Asus K55VM-SX064V (15.6 inch). Except from the metal palm rests the K75VJ is entirely made from plastics. We appreciate that all parts of the case are matte. In addition the lid has a surface texture which improves the grip. On the contrary, the case of the Pavilion is completely made from glossy plastics. Alike the Asus, Lenovo also mainly made the Ideapad from plastics, but used metal palm rests. Acer AS10D7E charger

The palm rests of the K75VJ are quite pressure resistant, but the other parts of the base unit are not that stable. The case slightly gives left and right of the keyboard. If you hold the base unit on one of the two front corners, the case slightly twists, but overall the stability is acceptable. The opened lid can also slightly be twisted and you'll observe a minimal color shift on the display, while it only slightly yields without recognizable image shifts under pressure. The hinges hold the lid stably in the adjusted position, but allow a minimal teetering. However, they are too stiff for one handed opening.

Contrary to the Pavilion and the Ideapad, which only deliver Fast Ethernet, the K75VJ houses a Gigabit Ethernet chip (RTL8168/8111) from Realtek. The WLAN module of our test sample stems from Atheros (AR5B125) and supports standards 802.11 b/g/n. A Bluetooth chip is not available, but a HD web cam is incorporated in the display frame.

In the box of the notebook the users will find a few thin guides, the warranty information and a short guide to Windows 8.

Operating System and Recovery
Asus delivers the 17.3-incher with pre-installed Windows 8 (64 Bit). A installation DVD does not belong to the scope of delivery, but the system offers a recovery system. In order to launch it, you need to hit F9 after switching the computer on.

  • asus u41jf AC Adapter/Charger

RAM, hard drive and WLAN module are accessible via a maintenance flap on the underside. In addition it is possible to clean the fan to some extent. The two RAM slots of our test model are already occupied (6 GB). The notebook supports up to 8 GB. It's easy to replace the hard drive. You simply need to loosen some screws and pull it out. Beside the hard drive there is also a second hard drive slot. So, you could equip the laptop with to hard drives: a fast SSD for the operating system and a conventional hard drive for the data. Unfortunately, a second hard drive cage does not belong to the scope of delivery.

Buyers of the K75VJ get a 24-month Collect and Return warranty. The Ideapad also comes with a two year warranty, but the Pavilion's is only 12 month. It is possible to enhance the warranty period of the Asus notebook to 36 month for about 70 to 80 Euro, but you need to buy and enable this warranty extension within 90 days after the purchase of the notebook.


Asus's K75VJ series consists of a number of general-purpose DTR notebooks. Their performance more than suffices usual tasks like Internet browsing and communication and video playback. Thanks to its GeForce GPU the laptop can also run demanding 3D games. We test the current top model of the series, which costs about 800 Euro at the time of writing. In addition Asus also offer two further models of the K75VJ product range with different CPUs, RAM and hard drive capacities, which are priced at about 700 (TY100H) and 750 Euro (TY101H). Acer AK.006BT.074 charger

Asus equip our K75VJ test model with an Intel Core i7-3610QM quad core Ivy Bridge CPU, which uses a base clock of 2.3 GHz. Its Turbo can increase the clock rate to 3.1 GHz (four cores), 3.2 GHz (two cores), or 3.3 GHz (single core).

In the Cinebench benchmarks the laptop scores as expected. The CPU works at maximum speed (3.1 Ghz) and, because of its faster CPU, our test model significantly outperforms Lenovo's Ideapad G780 (Core i5-3210M, GeForce GT 630M) and HP's Pavilion g7-2007sg (Core i7-3612QM, Radeon HD 7670M) in the CPU tests. However, the Pavilion is fastest in the GL test as it houses the strongest GPU of the three competitors.

Gaming performance
The K75VJ can play current computer games in medium and often also in high quality at a resolution of 1,366 x 768 pixels without problems. Frugal games like Fifa 13 and Counter-Strike: Global Offensive also run smoothly in FullHD resolution (1,920 x 1,080 pixels). In cutting-edge, performance-hungry games, like Hitman: Absolution the limits of the GeForce GT 635M GPU get obvious. This game can barely be played at medium settings. The following table about Anno 2070 depicts that the Radeon HD 7670M in the Pavilion is the fastest GPU in our comparison. Its frame rates are a tad higher than the K75VJ's.

Regardless of the scenario we are very satisfied with the surface temperatures. While idle the temperatures range from 25.6 to 33.1 degrees Celsius. Under full load (Prime 95 and Furmark) the values increase to 26.6 to 44.1 degrees Celsius. So, it is possible to use the 17.3-incher on the lap. In addition the cool palm rests (30 degrees Celsius) allow for a pleasant working experience. The Pavilion and the Ideapad get clearly hotter under full load.

During our stress test (Prime 95 and Furmark for at least one hour) the speed of the CPU varies in mains operation. It basically works at 2.3 Ghz, but sometimes the clock of all three cores is increased to 3.1 GHz. The longer the test runs, the less frequently this happens. Sometimes a single core is throttled to 1.2 GHz. The GPU starts the stress test with a clock rate of 661.5 MHz. After about 5 minutes it falls to 630 MHz. Sometimes the GPU throttles to 594.8 MHz. If the stress test is run in battery mode, the CPU basically clocks at 1.2 GHz. Sometimes it accelerates to 3.1 GHz. After initial up and downs (about 2-3 minutes, 67.5 MHz to 661.5 MHz) the CPU works at constant 661.5 MHz.

A general-purpose multimedia device like the K75VJ should deliver a halfway decent sound and the Asus indeed does. The two Altec Lansing speakers sit on the underside and sound somewhat voluminous, but lack bass. Speech is clearly audible. However, headphones or external speakers are recommended for a better audio experience.

Battery Life

Power consumption
While idle the power consumption is between 7.9 and 13.3 Watt. Considering the hardware inside, these are decent values, similar to the G780's and the HP Pavilion's. Under full load (Prime95 and Furmark) the power consumption increases to nearly 98.1 Watt, which exceeds the 90 Watt specified on the power adapter. While the IdeaPad is with 62.9 Watt much more frugal, the Pavilion also reaches a high value of 86.6 Watt. The differences are also quite notably under medium load (3D Mark 2006). The K75VJ (65,1 Watt) demands significantly more power than its competitors (HP: 44 Watt, Lenovo: 55.7 Watt).

Battery Life
When idle the K75VJ achieves a battery life of 5:33 h. The Pavilion (5:38 h) and the Ideapad G780 (5:49 h) only run a tad longer. We test the idle scenario by means of the Battery Eater Reader's test with energy saving profile, disabled WiFi modules and lowest display brightness. Under load the K75VJ only runs 0:55 h on battery. The HP's battery life of 0:46 h is even shorter, while the G780 does not shut down before 1:34 h. As usually, we used the Battery Eater Classic with maximum display brightness, high performance profile and enabled WiFi modules to record the minimum battery runtime.

Our Asus ends the WLAN test after 3:36 h (HP: 3:53 h, Lenovo: 3:22 h). Here our looping script automatically loads web sites in 40-second intervals. The energy saving profile is active and the display brightness is set to 150 cd/m². A full battery capacity is sufficient for 2:36 h DVD playback. The values of the competitors (Pavilion: 2:52 h, G780: 2:30 h) do not differ much. The DVD test is run with energy saving profile (or higher, if the DVD does not play smoothly), maximum display brightness and active WiFi modules. As the three notebooks have batteries with nearly identical capacities (HP, Lenovo: 48 Wh; Asus: 50 Wh) the battery runtimes are easily comparably. Acer AS10D charger

With the K75VJ, Asus offer a balanced system, which delivers an excellent system performance and a good gaming performance. When running usual tasks, it works quietly and does not heat excessively. In addition we appreciate its two year warranty period. A further pro is its second hard drive slot. Furthermore, the notebook also has a saving potential. If the performance of a Core i5 dual core CPU suffices your needs, you can opt for one of the other models of the series and save 50 or 100 Euros. Unfortunately the K75VJ series only comes with a moderate, poor-contrast display. If Asus used a better display, the computer would rate much better. Acer AS10D31 charger

If you focus on computer games, you should consider the Pavilion g7-2007sg, which achieves better frame rates. If you look for a quiet and frugal notebook, the Ideapad G780 is a good choice, but keep in mind, that Lenovo crops the performance of the CPU.
