My favorite laptop batteries

At the touch pad is a Acer Series V7.2 model of Synaptics, which supports a number of multi-touch gestures. But you can also

scroll with the optically selected vertical scroll zone, which is enabled by default, and with a horizontal scroll area to be

turned on first, however, still needs. Overall, the touchpad allows a wealth of configuration options and can also be turned

off simply by pressing Fn + F7,When not in use.

The touch pad is relatively short stroke and talk about their whole extension of time evenly. The built-in fingerprint reader

between them is next to a Kensington Security Slot is another security feature. The Acer Bio Protection Software Protection

makes it easy to set up this Apple A1175 Battery and replace password by now more comfortable reading a fingerprint.

When the screen is a panel of Optronics, namely a AUO41EC. Points According to the planned use as a professional device is a

mat, ie anti-reflection on surface. The 15.6-inch screen has a maximum resolution of 1366x768 pixels, so a 16:9 cinema-

friendly format. That we gain some respect to the standard 4:3 format with 1280x1024 pixels a few pixels in width, but must

make do with a smaller amount. For frequently vertically oriented Office applications, this means that more often and earlier

must be scrolled. On the other acer Aspire 6920 battery Page 1366 in the most wide enough to be able to represent about two

application windows side by side completely.

On measurement data disappointed the panel. The average brightness is just 158.8 cd / m2. The maximum of 178.6 cd / m2 was

measured in the central image area. There, the brightness in all directions from point, most bottom-left. There, only 144.7

cd / m2 measured. The brightness, however, for use in buildings. The illumination of 81% is good. Less of the high black

value of 1.12 like cd / m2. that, combined with the relatively low brightness results in a moderate contrast of only 159:1.

An outside bet is due to the matte surface, at least in the shadow problem. For use in direct sunlight would do
Acer TravelMate 7720 battery in any case more brightness.

The motherboard uses the Portege HM55Acer chipset. This was one, slipped under code name Arrandale built, Core i5 processor,

namely a core i5 430M. It is a dual-core processor, which clocks using the turbo technology depending on the workload 2:26 to

2:53 GHz. Thanks Hyper, four threads are executed simultaneously. Support for Virtualization Technology for Directed I / O

(VT-d), Trusted Execution Technology, and AES New
Apple iBook G4 12 inch Battery Portege M205 Instructions but remains

subject to more expensive i5 Core processors.

In addition to the processor in the integrated GMA graphics chip in the HD TravelMate 8572TG also a discrete graphics card

from Nvidia Geforce 330M was installed. This is an old acquaintance who we meet next to the Radeon 5650 from rival Acer

Portege M400 Series ATI, often in devices that are to some extent have good graphics performance. There is a middle-class

graphics card which supports DirectX 10.1 and also video decoding in graphics chip (PureVideo HD with VP4) for less CPU load

for HD decoding. Thanks to CUDA, DirectX Compute, OpenCL and PhysX support, the stream processors for other applications

are used. In contrast to the above-mentioned Mobility Radeon HD 5650 from ATI, 330M GT supports DirectX 11 effects and no

cuts also outperform slightly worse. Nevertheless, modern and sophisticated Apple MacBook Pro 15 inch Battery running DirectX

10 games on the GT 330M with up to liquid medium settings and medium resolutions.

The integrated graphics chip in the processor, a GMA HD is good for non-3D-intensive applications in any case also. This also

offers hardware acceleration of HD video decoding. As can be switched between the two graphics cards, and how this affects

the power consumption is below in the section "Battery Life" section.
