How to use the Asus and Sony batteries for your laptops
Asus laptop battery The implemented handwriting recognition in Windows 7 is capable of learning and generates good results after a bit of use. We didn’t notice streaks or other traces when inputs were made on the Lenovo via stylus during the test period, like we observed in the Dell Latitude XT2.
However, alternative pen tips from Wacom could improve this should it happen anyway. Lenovo also expressly advertises the gorilla glass screen (no multi-touch) as having a higher resistance and could be more durable with active pen inputting in the long run.
Normally, finger inputting is disabled as soon as the stylus is within a certain range of the screen. That didn’t always work as well as hoped for and is a bit annoying when the ThinkVantage tools are opened or other windows pop up when unintentionally touched.
You have many setting options, which are unfortunately distributed on several tools, to modify the sensitivity or disable specific functions completely. In particular inexperienced users should bring along enough time for configuration and practice.
The finger control accuracy is of course dependent on how fine your fingers can work. While you basically don’t need system-sided enlarged icons, files and script representation with pen inputs, a few haptic-focused users will sooner choose the medium display size of 125 dpi in system control.
You’ll especially want to use your fingers for opening files, clicking through pictures, etc. Newbies will also have to invest a bit of time for other functions, like gesture control, until use is really smooth.
As already mentioned, the ThinkPad X220t is available with two different IPS screens. Both have a resolution of 1366×768 pixels and consequently a dot density of 125 dpi, as well as an LED backlight that allegedly supplies a brightness of 300 cd/m2 (300 nits).
The gorilla glass screen, available for an extra charge, is described as an outdoor display without multi-touch support. In return, it’s especially resistant surface is supposed to impress. According to Lenovo, the current outdoor version doesn’t have a higher brightness of 400 cd/m2, like in the previous ThinkPad 201t, anymore.
X220t vs sRGBOur test device has the basic version with multi-touch support. Although it’s an anti-glare screen, the impression it makes is somewhere between matt and glossy displays.
Depending on the light situation, you can see vague outlines that, however, aren’t as annoying as on screens with a smooth screen. There are no display problems indoors, but you can’t always fall back on an ergonomic brightness setting of 140 – 160 cd/m2 without hesitation. Asus Laptop Battery
The vague reflections could be annoying. Since the LEDs only provide a luminosity of 256 cd/m2 in maximum and 244 cd/m2 in medium, the image overlays can be outshined well. However, we can’t confirm the 300 cd/m2 that Lenovo promises.
The screens homogeneous illumination of about 91% is very good. In regard to the measured rates, the brightness decreases a bit towards the lower screen edge. But this circumstance isn’t visible even on monochrome content.
Due to the digitizer layer, Sony Laptop Battery the screen surface has a slightly grained texture in addition to the semi-glossy quality. It doesn’t provide quite as a clear representation as the X220’s IPS screen when looked at closer. You can also see a dot matrix when it’s held against the light in a turned off state. But, more or less all displays of this kind had these effects and are a side effect of the additional input options.
The LED backlight can’t defy direct sunlight outdoors, but displayed content can still be seen satisfactorily when the seating position is well selected. They are also only overlaid by diffuse reflections. The maximum brightness is also available in battery mode. Toshiba Laptop Battery The good contrast ratio of 883:1 also has a positive impact on legibility of texts and Internet sites. Black and colors look really saturated and, alike the X220 with IPS screen, bid a good representation of pictures. In return, the color spectrum is only on the usual laptop level an reaches about 70% of the sRGB color space.
Bright content, lateral sunThe viewing angle stability is on a very high level, as expected from an IPS screen. Colors and content remain very stable for laptop conditions and grants good, even recognition and reproduction quality from all directions. Merely the brightness varies depending on the viewing angle. Differences between horizontal and vertical view aren’t discernible subjectively. Thus, very good prerequisites for use as a tablet.
