Nothing of the yielding keyboard (see design) is noticed during normal typing. Typing on the keyboard also proves to be overall very pleasant. The key drop and pressure point have been selected well and allow fast working. Even the typing noise is acceptable and not particularly loud. However, they sound a bit clattery in some areas but that doesn't affect their function in any way.HP 498482-001

The touchpad has a diagonal of 85 millimeters (76x47 millimeters) and is inserted into the wrist rest. This clearly separates the touchpad from the wrist rest, but recognizing the touchpad shouldn't be a problem due to its nubby surface anyway. The touchpad has two unmarked scroll bars, in addition to multi-touch. The touchpad proved to be precise and accurate during the test and actually didn't anything to be desired.HP EV06055

Both mouse keys are located directly beneath the touchpad. They stand out with a very short and hard key drop. A quiet click confirms whether or not the key has been triggered. There is no reason for complaint here, either. HP HSTNN-CB72

A display from LG Philips is used in the Sony Vaio notebook.HP HSTNN-CB73 The screen is a model with a glare surface and a resolution of 1366x768 pixels. That is too bad, considering that the laptop has been equipped with a Blu-Ray drive and that the screen can't render the full resolution of Blu-Ray movies. Thus, the user doesn't have much choice and has to use a HDMI cable to connect the laptop with a corresponding playback device. Then, movies can also be enjoyed in their highest Full HD quality.HP HSTNN-DB72

EH1Z1E/B vs. AdobeRGBWhen taking a closer look at our measuring results, it quickly becomes clear that Sony has sooner built a run of the mill screen into the Vaio EH1Z1E/B. The average brightness of 194.9 cd/m2 is also sooner lower midfield. Even the brightness distribution of 85 percent isn't convincing. Although the brightness difference can't be seen with the naked eye, some competitors do a better job here. At least Sony doesn't automatically reduce the brightness in battery mode.HP HSTNN-DB73

The screen shows more shortcomings with the black value. The black value of 1.31 cd/m2 is quite high. A rate below 1.0 would have been desirable. That also has an adverse affect on the contrast which isn't very high with 159:1.HP HSTNN-IB72

In terms of color reproduction, the screen won't convince professional users, either. The screen can't completely render the sRGB color spectrum and doesn't even come close to the AdobeRGB color gamut. But, normal users can confidently ignore this.HP HSTNN-IB73

The screen's specs already show that the Sony Vaio EH1Z1E/B is only suitable for outdoor use to an extent. Ideally, users should look for a shady place with the laptop in order to still recognize something properly on the screen. In addition to the moderate brightness and the poor contrast, the reflective screen makes the reproduction even more difficult.HP HSTNN-LB72

Viewing angles: Sony Vaio VPC-EH1Z1E/B When the display isn't tilted, the screen remains stable even in wider viewing angles. Thus, it's absolutely possible to sit in front of the notebook with several people without the content being distorted. The image only deteriorates quickly when the screen is tilted.HP HSTNN-LB73

The Vaio EH1Z1E/B relies on the Intel Core i5-2410M processor. This midrange dual core processor is currently very popular among notebook manufacturers and is frequently built into notebooks. The processor has a default clock of 2.3 GHz. Thanks to Turbo Boost, the clock can be increased to 2.6 GHz (both cores loaded) or 2.9 GHz (one core loaded). Thus, the processor is not only suitable for basic tasks like Internet surfing, but can also be loaded with demanding tasks. HP HSTNN-UB72

Image processing or games are also well possible with the processor. With a TDP of 35 watts, it corresponds with the majority of current Intel Sandy Bridge midrange processors and is suitable for laptops with a size of 14 inches or more. The Intel HD Graphics 3000 has been embedded directly into the processor and is more than suitable for basic graphic tasks. The Sony Vaio notebook doesn't use the Intel HD Graphics 3000, though.HP HSTNN-UB73

Instead, it relies on the Nvidia GeForce 410M. With the 410M, an entry-level graphics has found its way into the Vaio notebook. It is only slightly faster than the Intel HD Graphics 3000. The Nvidia card has advantages over the embedded Intel solution, especially in gaming. The 410M benefits from its dedicated memory and the superior drivers. Moreover, the 410M supports the bitstream transmission of HD audio (Blu-Ray) via HDMI port.HP HSTNN-XB72

As a result,HP HSTNN-XB73 it's possible to transmit Dolby True HD and DTS-HD via bitstream without loss of quality to a suitable receiver. This is an important feature particularly in connection with the Blu-Ray drive. However, the 410M doesn't support 3D Vision. It's simply not strong enough for that. Basically, it would also be possible to use the Optimus Technology with the 410M, but Sony hasn't used this option and thus it's not implemented. Consequently, the automatic switching between the Intel HD Graphics 3000 and Nvidia GeForce 410M isn't possible.KS524AA

We use the program, CineBench, to assess the processor's performance. The processor's cores are loaded both singly and collectively in this benchmark. Thus, it's possible to check if Turbo Boost is working properly besides checking the processor's performance. The built-in i5-2410M processor achieved a score of 4486.0 points in the Cinebench R10 Single Rendering (64 bit), and is thus in the good midfield of 2410M processors. HP 447649-251

A comparable score was achieved by, for example, the Medion Akoya P6631 (2410M, GT540M) with 4494.0 points. The Sony laptop lags far behind the rest of the field in the Cinebench R10 Multi Rendering (64 bit) benchmark and manages 7593.0 points. Consequently, it is one of the lowest placed notebooks with a 2410M processor. HP 447649-321

In comparison: An average score for the 2410M processor would be about 9600 points in this benchmark. The Asus X53E-SX082V (2410M, HD Graphics 3000) from the Intel TestIT!2011 campaign sets a good example with 9631.0 points. HP 454001-001

The Sony notebook is sooner in the field of the i5-430M processor from the prior processor generation with this score. For example,HP HSTNN-DB53 the Sony EH1Z1E/B is on a par with the Dell Inspiron 17R (430M, HD 5470) with 7554.0 points. There is certainly still need for improvement here. However, the Turbo Boost feature works without problems according to the tools we used (HWInfo 64). In our test, the processor could deliver the 2.90 GHz without further ado where necessary.HP HSTNN-OB53
