Conserve battery power—turn off backlighting

Align Screen asks you to tap on a series of five crosshair icons that appear in the center and four corners of the screen. Be sure to press down on the crosshairs as firmly and accurately as possible to ensure that your screen will be aligned correctly.

To overclock or not?

Intel's XScale processors have spawned a cottage industry in "overclocking" software. The XScale CPUs are designed to be able to run at more than one speed. The benefit is that CPU speed can be scaled to the task at hand: higher speeds for graphics-intensive or multimedia applications, lower speeds for spreadsheets and word-processing. Overclocking software overrides the built-in governors on the speed, pushing the processor to the max at all times.
