HP Envy TouchSmart 4-1102sg Ultrabook Review

A notebook with a touchscreen - that's still something unusual today (but not for long). But the HP Envy TouchSmart 4-1102sg isn't relying on this feature to make laptop owners envious. The manufacturer is also combining powerful speakers, a clever cooling system and thoroughly respectable inner-workings to make the device truly remarkable. ASUS G73SW-A1 charger

We'll see if owners of the Acer Aspire S7, the Asus VivoBook S400CA or the Sony Vaio SVT-1312V1ES really do have something to envy.

Case

Brushed metal is often a magnet for fingerprints - that's not the case here. That means the lid never looks smudged. Upon opening it, the screen stays true to the "black" color scheme on the outside surfaces, while around the black keyboard, silver is the dominant color.

At 2.1 kg (4.6 lbs) the device doesn't feel light, which is partly the fault of the screen's hard glass surface. With dimensions of 340 x 23 x 240 mm the device isn't exactly small either (14 inches). Asus A42-G75 charger

As is unfortunately common among most ultrabooks, you sacrifice user upgradeability and you are stuck with the default battery and other (normally user replaceable) parts.

Performance

Even if the device for review has exciting features at its command, you can't neglect the hardware behind it. The computing power is drawn from classic ultrabook components - an Intel Core i5-3317U and the Intel HD Graphics 4000. They are supported by a capacious 8 GB DDR3-SDRAM of working memory. A hard drive combination of a 500 GB HDD and a 32 GB SSD cache is also installed.

Processor
Intel Inside - in this case an Intel Core i5-3317U with the Ivy Bridge architecture. This runs with a base clock rate of 1.7 GHz, but the turbo theoretically provides clock rates of up to 2.6 GHz.

In the Multicore test with Cinebench R11.5, the review candidate lies at the same level as the Vaio SV-T1312, but behind the Acer Aspire S7 and the Asus VivoBook S400. In the OpenGL test, however, it triumphs over all three. When the devices are compared using Cinebench R10, the Envy doesn't do quite so well in the CPU tests - but for this chip it's at the expected level.

In the stress test the CPU stays at the clock rate of 1.7 GHz for the time being. First when the additional cooling reserves are freed via increased fan activity, the device jumps up to a maximum clock rate of 2.3 GHz. That would be a satisfactory result - if it weren't for the consistent throttling of up to 1.4 GHz due to the rising temperatures. But since all the benchmarks are at the expected level, restrictions due to throttling aren't forecasted with everyday use.

System Performance
The Envy gets the same number of points (4660 points) as the Sony Vaio SVT-1312V1ES in the PCMark 7 test. The Acer Aspire S7 outdoes them both (5020 points), but they bowl over the Asus VivoBook S400 (2823 points). Even the firm's own Envy 6-1000sg (which doesn't have a touchscreen and therefore isn't part of the competition) can't reach this score with 3529 points.

Storage Devices
Not one, but two hard drives are built into the device - though only one is available for active use. The passive SSD with 32 GB of space serves as cache which facilitates quick booting and fast access to recently started programs under Windows 8.

The conventional HDD is 500 GB and runs at 5400 rpm. In regards to the test with HD Tune, you shouldn't be fooled by the short-term power peak of 302.3 MB/s - the SSD jumps in for a moment. As it continues to operate, the write speed stays continually under 100 MB/s with numerous lows of about 1 MB/s.

Graphics Card
As is so often the case with notebooks containing an Intel processor, an Intel HD Graphics 4000 takes the role of the graphics card. Other models in the series like the Envy 6-1000sg (Intel Core i3-2367M as processor, no touchscreen) have their own graphics cards at their command - in the stated example, an AMD Radeon HD 7670M. The Envy Touchsmart isn't granted this luxury.

The 3DMark 11 performance test shows where the device stands in relation to similar devices and what their respective graphics cards can achieve. At 606 points, the Envy Touchsmart outpaces both the Asus VivoBook S400 (559) and the Sony Vaio SVT-1312V1ES (561 points, each with the same CPU/GPU combination). Thanks to its own GPU, the Envy 6-1000sg comes up with almost double the score at 1,172 points.

Gaming Performance
Just because it has a touchscreen doesn't mean you're restricted to playing Angry Birds. That's confirmed by the test with Anno 2070 and Diablo 3. The construction simulation and the Hack 'n' Slash games at their lowest settings run at a smooth 60 and 80 fps respectively. But that changes as soon as the graphic detail level is raised. With Anno 2070, the frame rate is cut in half at mid-detail settings; with Diablo 3 it slides down even further. At a high level of detail, neither of the two titles is playable.

The Envy isn't a real gaming laptop, but you can still enjoy fluid gameplay at low graphics settings, provided you're playing games with moderate hardware demands.

Emissions

The dynamically regulating fan continually provides the quietest background sound possible for a laptop: less than 31-33.9 dB without any appreciable load. Under mixed load the volume remains low to start with and only under full load do you hear clearly audible noises (up to 46.7 dB). In order for it to reach that point, quite a bit has to be demanded of the device. In practice you'll usually be confronted with a quiet, albeit softly audible device.

Temperature

In idle mode the temperature gauge doesn't cross the 30 degrees Celsius mark on the top side of the device. On the bottom, however, it does reach up to 34.1 degrees Celsius. The highest temperatures are measured in that same spot under high load. Up to 62 degrees Celsius are recorded - so to put the device on your lap under full load isn't a good idea, but for more practical Internet browsing or Office, use there isn't a problem.

The stress test (FurMark and Prime95 run for an hour) reveals how the temperatures inside the device can develop. The CPU reaches up to 77 degrees Celsius before the cooling finally fulfills its purpose. Working, first at full performance, the CPU temperature sinks to 68 degrees Celsius. Here a cooling system that jumps in to help a little more quickly would be ideal - but once the system's started running, the CPU stays relatively cool.

Speakers
Alongside the stereo speakers over the keyboard, there is an internal subwoofer. This combination increases the sound quality to an extent, but the "Sound by Beats" isn't really convincing. The only noteworthy thing here is the constant sound stability at high volume. Where cheaper speakers would weaken, you still hear clear sounds here. Although we are talking about better laptop speakers, they're no competition for external speakers or headphones. Asus C22-UX31 charger

Energy Usage
The device proves to be rather power-thirsty if you take a look at its power usage. An average usage of 10.8 watts in idle mode is usually undercut by other ultrabooks.

Also, under load, the average usage of 36.5 watts lies at the same level where other devices reach their maximum. But the power supply provides the necessary energy.

Although the battery only has 4 cells, they provide the laptop with energy for quite a long time. This review unit doesn't reach the level of the Sony Vaio SVT-1312, but a maximum battery life of 7 hours and 27 minutes is satisfying.

With everyday internet surfing, a fully-charged battery lasts 5 hours and 45 minutes; DVD playback with the external drive sinks this value to 3 hours and 12 minutes. The BatteryEater Classic Test reveals to us that the battery holds out at least 1 hour and 44 minutes.

When it comes to the features offered by the HP Envy TouchSmart 4-1102sg we're talking about a powerful mix. The touchscreen, the included external DVD drive and the speakers with a subwoofer lift the notebook distinctly above other media-laptops.

Whether the touchscreen really is a selling point depends on your own requirements for a mobile device. For those who find laptops too cumbersome and tablets too inflexible, here is an interesting balance. Unfortunately, the solution offered here brings disadvantages too. How sensible it is to buy a notebook with a touch display is therefore dependent on your own expectations.

At about 1000 Euro (~$1325) the device isn't cheap, but certainly exceptional. Anyone who is looking for a clever notebook that isn't for work purposes should definitely take a look at the HP Envy TouchSmart 4-1102sg.

Review Sony Vaio VPC-CB2S1E/B Notebook

Sony has unveiled the new Vaio VPCCB2S1E/B, a new model in the C series. The Vaio CB2S1 is intended to be a stylish portable companion that handles multimedia tasks particularly well. In any case the Full HD display and the integrated Blu-ray drive make this abundantly clear. But the notebook's hardware is impressive in other respects too. As well as a processor from Intel's latest Sandy Bridge family, you get a graphics card from the AMD HD 6000 series. A backlit keyboard with a separate number pad should round off the package nicely. Sony VGP-BPS23/B

The Sony Vaio VPCCB2S1E/B certainly knows how to dazzle, but is it more than just a pretty case? Find out in our review.

Sony's notebook cases usually stand out with their attractive designs and good build quality. The Vaio VPCCB2S1E/B is no exception. The black design (or white if you prefer) makes an excellent first impression, and has a number of interesting gimmicks to entice you. A 3D effect has been built into the lid and the area below the palm rest, which makes it look like there are little square boxes under the surface. It's a nice effect, but it also has its downsides - every single one of the notebook's surfaces are high-gloss plastic surfaces. These seem to magically attract fingerprints and greasy smudges, and are quickly covered in them. So you should always carry a soft microfibre wiping cloth with you in your notebook case. Despite this, we actually really like the 3D effect created by the plastic surfaces. It is particularly striking in the palm rest area. Depending on how the light falls on the surface, the pattern underneath will sometimes glow blue (clearly visible in our photographs). Sony VGPBPS23/B

In terms of build quality, the Sony Vaio notebook does not lag behind its rivals; it doesn't make cracking or creaking sounds. And even the display lid strongly resists being twisted, although it is also comparatively thick. The two display hinges hold the lid firmly in place, but only after it has stopped wobbling backwards and forwards a few times. It is possible to open the laptop with one hand, but the base unit is pulled upwards a little with the lid. The Sony Vaio's base unit appears solid. The palm rests hardly flex at all even under heavy pressure, but the keyboard is not as resistant to pressure as you would hope. In the centre it is still fairly sturdy, but the closer you get to the edges, the spongier it gets. It is particularly noticeable in the number pad area - which you can feel flexing even during normal use.

There are two access panels on the underside which allow you to upgrade the Sony Vaio VPCCB2S1E/B, although they have only given you access to the RAM and the hard drive. The rest of the hardware is kept away from the user.

We evaluated the processor performance using the Cinebench benchmarks, versions 10 and R11.5. In the Cinebench R10 single rendering (64 Bit) benchmark, the Sony Vaio VPCCB2S1E/B scored 4631.0 points. Compared with other notebooks which use the Intel Core i5-2410M, the Sony notebooks stands up well. There are only a few notebooks with the same processor that are faster than the Vaio. The frontrunner of these notebooks is the MSI A6400-Ci507 S (2410M, HD Graphics 3000) with its 4670.0 points. That is only 39 points better. In the Cinebench R10 multi-rendering (64 Bit), the Sony Vaio again scores very well compared to its rivals. With 9827.0 points, it is once more only a short way behind the fastest notebook with a 2410M processor. The Acer Aspire 5750G (LX.RAZ0C.008) (2410M, GT 540M) has a very narrow lead with 9840.0 points.

To determine the overall system performance of the Sony Vaio VPCCB2S1E/B, we used both the PC Mark Vantage and PC Mark 7 benchmarking programs.

In the PC Mark Vantage benchmark, the notebook scored 6150.0 points overall. This places it in the upper third of our table of benchmark results. Compared with the other notebooks which use the Intel Core i5-2410M processor, the notebook does not do badly, finishing near the top of the middle section. In the same region as the Sony Vaio are notebooks like the Dell XPS 17 (840QM, GT445M) for example, which scores slightly higher than the Vaio with its figure of 6153.0 points. The 15-inch Apple MacBook Pro 2011-02 MC721LL/A (2635QM, HD6490M) even finishes below the Vaio with 6133.0 points.

For the PC Mark 07 test, the result does not look as good, but we have not been using this benchmark in our reviews for that long and so the results table is not as well populated as the one for the PC Mark Vantage test. Here, the Sony Vaio falls behind its competitors with the same processor. It scores 1732.0 points. Notebooks with similar hardware like the Dell Vostro 3450 N34506 (2410M, HD 6630M) achieve significantly higher results (1911.0 points in the case of the Dell notebook).

In order to judge the graphics performance of the Sony Vaio notebook and the AMD Radeon HD 6630M graphics card, we used the 3D Mark 06 benchmark. But since the AMD graphics card is also DirectX 11 capable, we will also take a quick look at the 3D Mark 11 benchmark.

In the 3D Mark 06 test, the Sony notebook just manages to land in the upper half of the benchmark table with 6806.0 points. If you look just at other notebooks fitted with an AMD Radeon HD 6630M, it is again noticeable that the Sony has a mid-table position. The notebook with an AMD Radeon HD 6630M that scores the most points is made by Dell; it's the Dell Vostro 3450 (N34506 (2410M, HD 6630M) and it scores 7269.0 points. The lower boundary is marked by the Lenovo ThinkPad Edge E420s-NWD4NGE (2410M, HD 6630M) with 6432.0 points. The Sony Vaio VPCCB2S1E/B falls exactly in the middle of the comparable notebooks.

The 3D Mark 11 confirms the result that the 3D Mark 06 gave. Compared to notebooks with similar hardware, the Sony machine is again in a mid-table position. Its result of 987.0 points places it once again between the Lenovo ThinkPad Edge E420s-NWD4NGE (2410M, HD 6630M) with 970.0 points and the Sony Vaio VPC-SA2Z9E/B (2620M, HD 6630M) with 1023.0 points. So the Sony Vaio VPCCB2S1E/B does not break any records, but its results are solid and speak to a good level of performance.

Gaming Verdict

HP Folio 13 Battery

To determine the notebook's gaming potential, we tested it with StarCraft 2: Wings of Liberty and Call of Duty: Black Ops. The first game is a real-time strategy, while the second is a first-person shooter.

StarCraft 2 played without any difficulty on the two lower settings (minimal and medium). The frame rates were a long way from the outer limits of playability. From the 'high' setting onwards (1360 x 768, other settings on high) it starts to get trickier. The 27 fps that it manages is only just above the 24 fps needed for the picture to appear smooth. When you hit the 'ultra' settings (1920 x 1080, other settings on ultra) the game can no longer be played fluidly, at 17 fps.

Call of Duty: Black Ops is a little less demanding, and can be played without stuttering up to a resolution of 1360 x 768 and with high details. But with this game too, the ultra settings (1920 x 1080, 4x AA, 8x AF, ultra textures) bring the frame rate below the 24 fps threshold, at 22 fps.

But these results are more or less what we expected, and match the results from notebooks with similar hardware that we have already tested. You can see the benchmark results of other games on the AMD Radeon HD 6630M in our comparison 'Computer games on laptop graphics cards'.

Temperature

When idle, the Sony Vaio has no problem cooling its internal hardware. The temperature of the case also stays in the green zone. The palm rests only reach 24.8 degrees Celsius (left-hand side) and 27.1 degrees (right-hand side). The touchpad, also in this area, reaches 26.1 degrees Celsius. And things do not look very different on the underside of the notebook. The maximum temperature is just 27.5 degrees Celsius, which is completely unconcerning, whether you have the machine on the table in front of you or on your lap.

Under heavy use, the temperatures start to climb significantly, as you would expect. On the top side the maximum temperature rises to 33.1 degrees Celsius. The palm rests heat up to 32.6 degrees (left) and 27.2 degrees (right). The touchpad reaches 33.0 degrees, making it almost the hottest area on the upper surface of the base unit. On the underside, the notebook hits a maximum of 40.9 degrees.

We simulate full system load by running two programs, Prime 95 and FurMark, to place the greatest possible stress on the processor and graphics card. But the Sony Vaio VPCCB2S1E/B was not overly troubled by them. According to HWinfo, the maximum processor temperature was 75 degrees Celsius; this is well out of the danger zone, with plenty of breathing space. Nor did we observe any throttling of the processor or graphics card. The 3D Mark 06 benchmark test that we carried out subsequently gave us no reason to believe that the performance of the notebook had been in any way reduced by the extreme stress.

Speakers

The Sony notebook's audio system is very good, as long as you don't turn it to maximum volume. The sound is clear, and generally of a very decent quality. Of course the low and bass tones are completely absent, as with the majority of notebooks. But you can still listen to music or a film on them. Those who have higher standards when it comes to sound quality should be practical and attach some headphones.

Battery life

The Sony Vaio's battery life is reasonable when in idle; with very few demands on the system, the energy consumption is between 11.9 and 21.2 Watts. In this mode the energy-saving mechanisms of the processor and graphics card are active, which keeps the energy use low. However, when the demands on the hardware increase, the energy consumption leaps to 57.9 - 79.9 Watts. If you burden the system with Prime, which leaves the graphics card alone as much as possible, the notebook draws 68.2 Watts. With heavy use from FurMark, which conversely stresses the graphics card whilst leaving the processor as far as possible undisturbed, the energy consumption is 68.0 Watts.
The run times achieved by the Sony Vaio VPCCB2S1E/B are not exactly overawing. The Battery Eater program was used to determine battery life. In the Reader setting, which simulates idle use of the laptop, the battery lasted just under 4 hours (3 hours 58 minutes to be exact). The result of the WLAN web surfing test is somewhat more realistic; here the notebook lasted for 2 hours and 30 minutes. If you like to watch a DVD when you're on the go, you can rely on 2 hours and 6 minutes of battery life. Under full load the battery only holds out for 55 minutes. To fully recharge the battery, you'll need a very long 2 hours and 55 minutes. This is longer than the battery even runs for during WLAN surfing.

Verdict

We very much like the look of the Sony Vaio VPCCB2S1E/B, even if the glossy plastic surfaces require near-constant cleaning. The build quality was generally convincing, though Sony showed it is not immune from small deficiencies. The display is undeniably the most impressive feature. With Full HD resolution and an integrated Blu-ray drive, the notebook is outstandingly well equipped to provide mobile multimedia enjoyment. But the display also won us over with its contrast, which was commendably high. The only thing to let the side down was the colour reproduction.

The combination of Intel Core i5 processor and AMD mid-range graphics turned out to be a sensible pairing, not only suitable for multimedia or office uses but also able to provide an enjoyable gaming experience. In terms of application performance, the notebook was convincing; it didn't take the top spot in comparison with other similar notebooks, but it was always near the top of the middle league. The games we tested ran very well for the most part. If you don't insist on the absolute highest settings all the time, you can play quite happily on the Sony Vaio.

We found the keyboard flexed easily, which was a little disappointing. Even when typing quite normally, we could feel it giving way by a few millimeters. Aside from this objection it is a very good keyboard, so we would still rate it as good.

Overall we liked the Sony Vaio VPCCB2S1E/B, which turned out to be a thoroughly serviceable multimedia and work notebook. If you prize high resolutions and can live with the glossy surfaces of the case, you should be happy with the Sony Vaio.

Review Dell Latitude E6230 Notebook
With their Latitude laptops, Dell wants to score points with business users in terms of performance, durability and scalability. Being 12.5-inches wide, the Dell Latitude E6320 is the smallest and lightest member of the Latitude E-family. Those who find this too small can go for one of the larger sister models. On offer are models from 13.3-inch (E6330 – review will follow shortly) to 14-inch (E6430) and up to 15.6-inch (E6530 – review will follow). DELL Vostro 3360 Battery

As usual with Dell, comprehensive configuration options are available to consumers. Our E6230 review device was equipped with a Core i5-3320M CPU, Intel HD Graphics 4000, 4 GB RAM and an SSD. Should some components of your choice not be available in the online configurator, ordering by telephone might help, as then the possible options are often more extensive. DELL Vostro 3460 Battery

In the course of the review, we will not only clarify what strengths and weaknesses our review candidate has, but we will also compare it to its direct competitors, the recently reviewed HP EliteBook 2570p, Fujitsu Lifebook P772, and Lenovo ThinkPad X230.
Dell talks about a tri-metal case. Various metals are used for its production: a magnesium alloy, anodized aluminum at the display lid, and a powder-coated magnesium base. Thanks to this choice of materials, a very good stability can be achieved despite the light and slender design. Both the base unit and the display lid hardly get deformed when exposed to pressure and winding forces. Additionally, Dell had the case tested for resistance against dust, shaking and extreme temperatures, according to MIL-STD-810G. DELL Vostro 3560 Battery

The strong hinges are manufactured from metal. The hinges' tension is so great that opening the laptop with just one hand is not possible. They cannot, however, entirely prevent wobbling after adjusting the opening angle. Being bent upwards, the rear edge also limits the opening angle to c. 125 degrees. DELL Latitude E5430 Battery

They cannot, however, entirely prevent wobbling after adjusting the opening angle. Being bent upwards, the rear edge also limits the opening angle to c. 125 degrees.

Processor
In our test candidate, a Core i5-3320M dual core processor with a base clock rate of 2.6 GHz is at work. Thanks to Turbo Boost technology it can - provided appropriate cooling – clock up to 3.1 GHz putting load on both cores, and 3.3 GHz in single core applications. Also, hyperthreading enables processing up to four threads simultaneously. Please take detailed information on the processor from our special page. Our benchmark list of mobile processors enables ratings according to performance. DELL Latitude E6430 Battery

We will see whether the device conforms to our expectations by running a series of CPU-demanding benchmarks. We compare the results with those of three direct competitors of which two, namely Lenovo's ThinkPad X230 and Fujitsu's Lifebook P772, are equipped with the same processor and give almost the same results. HP's EliteBook 2570p is equipped with a slightly faster Core i7-3520M and yields slightly better results. Details can be taken out of the diagram below. DELL Latitude E6430s Battery

System Performance
Our review candidate owes its outstanding results in both PCMark tests mainly to its fast mass storage, an SSD. Again, detailed values can be taken from the diagram below. Unfortunately, we do not have any PCMark7 results for HP's EliteBook 2570p in our database. In the PCMarkVantage, however, it is the only one of the three direct competitors that is even slightly faster than our Latitude E6230 model, as it is also equipped with an SSD. In contrast, Fujitsu's Lifebook P772 and Lenovo's X230 are much slower than our review model, with -36% in PCMarkVantage and -44% and -30% respectively in PCMark 7. However, if one chose a configuration with an SSD for these two, they would catch up. DELL Latitude E6430 ATG Battery

Storage Devices
When it comes to mass storage, the user is confronted with the agony of choice. At choice are currently conventional hard drives with 7200 rpm and 320 or 500 GB capacity or Solid State Drives with 128 GB or 256 GB. Those who appreciate fast access and loading times and can get by with less capacity will prefer an SSD over a hard drive with rotating parts. The former storage option also works silently. A close comparison of SSD and HDD can be found here. DELL Latitude E6430 XFR Battery

Our review model is equipped with a 256 GB SSD named Samsung SSD PM830 FDE 2. With the results it achieved it is roughly on the same level as Intel's SSD 510 Series and OCZ's Vertex 3, whereas one or another achieves better results in CrystalDiskMark depending on the test. Most of the time, the Samsung SSD performs better than the Vertex 3 and the Intel 510 when it comes to writing, except in 4K-writing where the Vertex 3 is the leader. Intel's SSD 520 Series, however, is faster across the board. DELL Latitude E6530 Battery

Graphics card
As is frequent with subnotebooks, the user gets no discrete graphics card but has to get by with a graphics chip integrated into a processor. Here, the main focus is put not on graphics performance, but on mobility, and thus also on a longer battery life. Therefore, as expected, there is not even an optional configuration with a discrete graphics card.

In any case, for the intended application area, namely mobile office and internet applications, the Graphics 4000 is quite sufficient. One should give up on 3D-demanding applications, though. The E6230 is definitely no mobile work station nor a mobile gamer. DELL XPS 13 Battery

In order to compare graphics performance, we use 3DMark tests as usual. Fortunately, the particular results obtained there are fully equal to other laptops with the same graphics chip and processor. Only Fujitsu's Lifebook P772 stands out splendidly - with for instance +28% in 3DMarkVantage - from the other review devices with 3320M CPU and Graphics 4000. An analogue statement can be made about practical gaming usage. In the best case, latest games are smoothly playable in low resolution and with minimal details. DELL XPS 13-L321X Battery

Emissions

Thanks to its silent SSD, our test candidate works silently when under little load. In this scenario we measured a consistent 28 dB(A). This is equal to the background noise of a silent environment. With increased load, the fan spins faster and gets clearly audible with maximally 43.4 dB(A). The noise characteristic is characterized by a rather high frequency, but it remains constant.

When under little load, our review model remains cool. When the inner components are stressed a lot, the device heats up to and above 40 °C. As the intended area of usage is office and internet applications, and at most light 3D tasks, this should be no practical problem. DELL XPS 13-L322X Battery

In the stress test we see how the laptop copes with lasting maximum CPU and GPU load. Then, core temperatures of the CPU and graphics chips rise a lot and reach 100 °C and over. The CPU's clock rate does not drop below the base rate of 2.6 GHz though, and the graphics chip also clocks at a stable 1.2 GHz. The 3DMark06 results obtained immediately after the stress test are equal to the cold run, except some insignificant deviation. DELL XPS L321X Battery

Speakers
The stereo speakers are located at the bottom side of the device's chamfered front edge and their sound hits the table. This has a positive effect on the richness of the sound. The sound thus appears to be surprisingly balanced, as long as the device is located on the table; the maximum volume, which does not distort the sound, is also alright for interiors.

Energy Consumption
The energy consumption is okay for a configuration with Core i5-3320M CPU and Graphics 4000 graphics chip. The idle results here beat every other laptop with the same CPU. The 65 watt power adapter is sufficiently dimensioned for an energy consumption of 53 watt. DELL XPS L322X Battery

Battery Life
Our review model was equipped with a 58 Wh Lithium ion battery which sticks out at the rear side. By contrast, a 65 Wh battery is listed when configuring in Dell's online shop.

The maximum battery life, calculated with the BatteryEater Readers test and minimal brightness, energy saving profile, and disabled wireless modules, is almost 10 hours. The minimum is only almost 2 hours. This result was also recorded with the BatteryEater Tool, however, in the Classic Test at maximum brightness, peak performance profile and enabled Wi-Fi modules. In our practice-oriented WLAN test, every 40 seconds a new page with different contents is accessed. This test was done with the energy saving profile and a brightness of 148 cd/m² (dimmed two levels). Under these circumstances, the user can surf the internet for about 5.75 hours via Wi-Fi hotspot. Dell Precision M4600 Battery

Fujitsu's Lifebook P772 achieves slightly shorter battery run times with its 63 Wh battery, but it also is a bit brighter. Lenovo's X230 reaches a slightly longer battery life with its well-lighted IPS screen. HP's EliteBook 2570p has the lowest screen brightness of all the devices in comparison. In return, it lasts a bit longer despite having the smallest battery with 55 Wh.

Small subnotebooks are designed for mobile use. Consequently, they should be robust and durable, have a long battery life and good system performance and enable outdoor use without restrictions. Dell Precision M6600 Battery

Thanks to the tri-metal chassis, the Latitude E6230 Models fulfill our first criterion. The fast SSD inside provides short boot and loading times and contributes considerably to the laptop's excellent performance. Although one cannot spend a whole workday away from a power outlet due to the battery, the battery life proves to be good in comparison to the direct competition.

Also, one can be very content with the communication features and the input devices. A major weak point remains though: the slightly too dark and dull screen. Its brightness is simply not enough for outside use. DELL Vostro V131 Battery

In the course of the review we have compared the subnotebook to its direct competition. Of them, HP's 2570p provides the best application performance but unfortunately also the lowest screen brightness. Though Fujitsu's Lifebook P772 is a little brighter than out review candidate, only the ThinkPad X230's IPS screen is suitable for use in sunlight; it also features wide viewing angles. Depending on the intended usage scenario one should carefully balance the pros and cons of the individual models. DELL Vostro V131D Battery

Review HP Pavilion g6-1352eg Notebook.
We recently took a closer look at the 17 inch Pavilion g7-1353eg. Now, the 15 inch version of the affordable multimedia notebook faces our tests. It's not very surprising that HP has the Pavilion g6-1300 available in several versions. Acer TravelMate TM5740-X522DF battery For example, we find Intel-based devices that are equipped with either a Pentium B960 (2.2 GHz, 2 MB L3 cache) or a Core i5-2450M (2.5-3.1 GHz, 3 MB L3 cache). Beyond that, a few AMD devices are also available. They aren't quite as expensive and feature the dual core A4-3305M (1.9 GHz, 1 MB L2 cache).

There are also differences found in the graphics card configuration: While some models have to be satisfied with Intel's HD Graphics 3000, other models are accelerated by the Radeon HD 7450M and/or the Radeon HD 6480G. The hard disk capacity ranges from 320 to 640 GB and that of the main memory is either four or six GB. Acer TravelMate TM5740-X522DHBF battery They all have the operating system (Windows 7 Home Premium 64 bit), optical drive (DVD burner) and screen (1366x768, glare) in common.

We opted for one of the lower priced alternatives with the Pavilion g6-1352 (RRP: EUR 499) and put it through its paces.

Like its bigger brother, the Pavilion g7, the case makes a good impression. The rounded shape and the charcoal gray surfaces (lid & keyboard bezel) give it a unique look. The high-gloss finish is definitely a matter of taste; we would have preferred a matt finish because of the high (smudge) susceptibility. Acer TravelMate TM5740-X522DOF battery

The buyer shouldn't expect too much from the notebook's quality because HP only uses plastic. Although a few components aren't quite flush (e. g. the transition between the lid and display bezel), we deem the workmanship to be acceptable. The stability is also all right, with exception of the somewhat wobbly lid. The top can be depressed in several places, but the bottom hardly yields. Another advantage: The 15 inch laptop can be carried around conveniently thanks to the moderate weight (~2.4 kg) and the moderate dimensions (374 x 245 x 36 mm). Acer TravelMate TM5740-X522DPF battery

Meanwhile, the metal-like hinges have room for improvement. Although they are pulled fairly tight (the base unit lifts evidently when the device is opened), surface vibrations cause the display to teeter. However, it should be possible to ignore that in view of the laptop's price. Overall, the case quality is located in the midfield.

Performance

Processor: AMD A4-3305M

Acer TravelMate TM5740-X522F battery To be able to offer the Pavilion g6-1352eg for a low a price as possible, HP uses a low-end dual core model from AMD. The A4-3305M is codenamed Llano, is manufactured in a 32 nm process and is - despite one billion transistors - one of the weakest CPUs currently available on the market. Clock rates of 1.9-2.5 GHz are fairly slow compared with Intel's Sandy Bridge models. For example, the popular Core i5-2430M runs with 2.4-3.0 GHz.

Acer TravelMate TM5740-X522HBF battery Moreover, it has a small L2 cache. Unlike the more expensive A4 models, the A4-3305M only has 1024 rather than 2048 KB. Intel's Sandy Bridge generation is equipped with a three to eight MB L3 cache. The TDP of 35 watts are acceptable considering that the A4-3305M contains the memory controller and an integrated graphics chip (Radeon HD 6480G). The dual core can also be called APU (accelerated processing unit) due to the amount of components.

System Performance

Acer TravelMate TM5740-X522OF battery The system benchmarks make it very evident that the Pavilion g6-1352eg is located in the entry-level field. Many devices only have a weary smile for a PCMark 11 score of 1313 points. Typical midrange notebooks, such as the Packard Bell EasyNote TS13HR-197GE (Core i5-2450M & GeForce GT 630M), easily surpass the HP device by 50%. There are more powerful alternatives in the EUR 500 range available (e. g. the Lenovo G770 M533PGE).

Gaming Performance

Acer TravelMate TM5740-X522PF battery The 15 inch laptop isn't really suitable for up-to-date games. Most tracks can only be played in low or medium details, because CrossFire rarely provides a benefit and the user is often troubled by micro-stuttering. Some shooter highlights (e. g. Battlefield 3 or Crysis 2) shouldn't even be considered. Even antialiasing isn't always possible. Casual gamers, who occasionally want to try out a new game, won't be happy with the Pavilion g6-1352eg in the long run.

Battery Life

Acer TravelMate TM5742 battery The 15 inch laptop's power consumption is pleasingly low. 9-12 watts in idle mode and 34-46 watt in higher load are evidence for undemanding components and good energy saving mechanisms. Multimedia notebooks usually consume more power. We measured a maximum power consumption of 89 watts in the Acer Aspire 5755G-2678G1TMtks (Core i7-267QM & GeForce GT 630M), so about twice as much.

Verdict

Acer TravelMate TM5742-X732 battery The Pavilion g6-1352eg notebook can't deny that it has been designed for a low price. It starts with the 15 inch plastic case that only sports a few interfaces, a clattery keyboard and a below-average screen. No matter if it's the brightness, black value or viewing angles: The reflective glare screen can't convince in any point. Videos and games sometimes look extremely gray and pale.

Acer TravelMate TM5742-X732D battery The performance also lags behind the expectations. Although a dual GPU configuration sounds exciting on paper, the result is occasionally more a pain than pleasure. In addition to the fluctuating performance (the CrossFire configuration is frequently slower than a single GPU in DirectX 9 games), the extreme micro-stuttering is particularly annoying. Hardly a current game really runs smoothly; stutters occasionally turn up even in medium or low details. We would have liked the notebook a lot more with simple graphics switching. Acer TravelMate TM5742-X732DF battery

But that is enough of complaining. The Pavilion g6-1352eg also has a lot of strengths. The 15 inch laptop's biggest advantage, compared to other multimedia devices, is that it's surprisingly quiet and cool. The fan pleasantly stays in the background during 3D applications and video files can be enjoyed adequately. HP also deserves praise for the compact power adapter and the low power consumption. Nevertheless, the all-rounder doesn't receive a general purchase recommendation from us. Acer TravelMate TM5742-X732DHBF battery

Review HP Pavilion g7-1353eg Notebook

Price-conscious users looking for a versatile notebook will likely prick their ears when hearing about the Pavilion g7-1353eg. The 17 incher, currently available for about EUR 540, can boast with a surprising amount of hardware.

For example, it has a quad core processor from AMD. The A6-3420M only clocks with 1.5 GHz, but it has an integrated graphics chip (Radeon HD 6520G). To increase the performance even more, HP treats the multimedia machine to a second graphics card. Acer TravelMate TM5742-X732DOF battery The Radeon HD 7450M is a brand new entry-level model that runs in CrossFire mode with the HD 6520G.

Nor is six GB of RAM and a 750 GB HDD found in the price range of EUR 500 every day. A conventional DVD burner serves as the optical drive. The operating system, Windows 7 Home Premium 64bit, is preinstalled. The high-gloss screen has a resolution of 1600x900 pixels. Acer ZG5

Although the case's quality can't keep up with that of a Pavilion dv7 or Envy 17, the case is absolutely acceptable for EUR 500. Like most contenders, HP completely relies on plastic. That is clearly noticed when taking a closer look at the laptop. The material nevertheless makes a robust impression; the workmanship hardly gives reason for complaint with the exception of smaller details (transition between display bezel and lid could be a bit finer). Acer UM08B74

The sensitive high-gloss finish isn't as convincing. Dust particles and fingerprints soon accumulate, in particular on the lid and in the keyboard area. However, stains are well-hidden since the surfaces are made of an elegant gray color. Apart from the fairly wobbly screen, we would describe the notebook's stability as acceptable. The top only yields around the drive and battery area under stronger force. Acer UM08B73

Meanwhile, the hinges are pulled fairly tight, which leads to the base unit lifting up along when the device is opened (both hands are needed for opening). Vibrating surfaces nevertheless cause the screen to teeter evidently. Dimensions of 412 x 268 x 37 mm and a weight of 2.8 kg aren't anything unusual. Most 17 inch devices are within the same range.Acer UM08B72

Performance

Processor: AMD A6-3420M

HP has opted for a low-priced, entry-level quad core processor from AMD. The installed A6-3420M (codenamed Llano) is not a CPU in the usual sense, but more an APU (accelerated processing unit), which fuses several processor cores, a graphics chip, as well as the memory controller and other functions on one die. Acer UM08B71

The integrated Radeon HD 6520G (320 shaders, 400 MHz core clock, no dedicated memory) makes a good impression when compared to Intel's Sandy Bridge counterpart, HD Graphics 3000, but the CPU performance is noticeably lower due to the lower default clock of 1.5 GHz. The Intel contender is also superior with a three to eight MB L3 cache, in contrast to the four MB L2 cache in the AMD graphics. In return, the manufacturing process of 32 nm is state of the art. The thermal design power of 35 watts corresponds to most i5 models. Acer UM08A74

System Performance

In the competition against other multimedia machines, the HP would often leave the field as a loser. The fairly lame quad core CPU and the relatively weak graphics chip combo lead to rather poor benchmark results. 4656 points in PCMark Vantage are by no means a sensation. The one or other office device achieves a higher score (4832 points @ Dell Latitude E5420). But then again, this 17 inch laptop only costs about EUR 500! Acer UM08A73

Gaming Performance

As can be seen in our gaming chart, the Pavilion g7-1353eg has an awfully hard time with the latest tracks. Maximum graphic options are only possible in the odd case. The 17 inch device also tends to struggle in medium details. A few games aren't rendered smoothly even in low details.

Acer UM08A72 High resolutions, like the native 1600x900 pixels, are often beyond the range of the possible. This makes it twice as aggravating that the multimedia laptop doesn't support 1366x768 pixels (1280x720 pixels result in an extremely blurred picture). Moreover, the CrossFire configuration sometimes calculates slower than a single Radeon HD 7450M. Users who want to occasionally play a small game should therefore carefully consider buying this notebook. Significantly faster devices are available for an additional EUR 100 (e. g. the Acer Aspire 7560G).

Battery Life

Acer UM08A71 A big advantage of the low-end components is the moderate power consumption. The notebook is satisfied with 40 to 60 watts even in higher loads. The Pavilion g7-1353eg is even happy with 11 to 17 watts in idle. The Acer Aspire 7560G has a similar power consumption despite faster hardware.

More would certainly have been possible in terms of battery runtime. A 6 cell battery with 47 Wh may be common for the industry, but such a model isn't suitable for long trips. Like many other multimedia devices, the HP laptop only manages for one hour in BatteryEater's Classic test (maximum brightness). Acer UM08A51

The battery runtime increases noticeably in normal conditions. For example, it's possible to enjoy a DVD movie for almost two hours; wireless surfing is possible for about three hours. The battery is first drained after over five hours in the ideal case (no load, minimum brightness, CrossFire off). Nevertheless, HP pointlessly wastes potential in this category.Acer UM08A31

Verdict

The Pavilion g7-1353eg offers a quite successful blend of price, performance and quality. Although the 17 inch device doesn't really excel in any point, the multimedia notebook hardly makes any major blunders, either.

Above all, there is the mediocre screen on the con side. HP uses a viewing angle dependent and intensely reflective low-end screen that reproduces a grayish black and "scores" with a low contrast, like the majority of contenders. Acer LC.BTP00.017 Not everyone will take a liking to the touchpad's dotted surface texture and the somewhat clattery keyboard, either. The connectivity (no USB 3.0) and mobility also have room for improvement.

On the other hand, HP deserves praise for the low power consumption and moderate emissions. Regardless whether idle or 3D mode: The multimedia laptop is never particularly warm or loud. Unfortunately, we can't make a general statement about the performance. Acer lc.btp00.127 Although two graphics cards and a quad core are truly remarkable for EUR 500, there are a few points to criticize in the details. For example, AMD's quad core A6-3420M can't compete with Intel's current Sandy Bridge generation - despite the cutting edge idea.

The CrossFire mode also proves to have a lot of problems, such as micro stuttering or a partly poor DirectX 9 performance. Standard notebooks with only one graphics card are less error prone and more comfortable in maintenance. Acer as10d75

Overall, the g7-1353eg is primarily suitable for users focused on versatility and who don't want to spend more than EUR 600 on a notebook.
