Occasionally, a laptop's touchpad will behave abnormally. This behavior includes the pointer jumping to a corner of the screen, or moving wildly. On current software (release 8.2 or better, consider upgrading!), the touchpad will be automatically recalibrated when this happens. You should hold your fingers away from the touchpad when this happens.

A recalibration of the touchpad can be manually invoked using the "four-finger salute" (Escape + Frame + Right Arrow + Fn, with Fn pressed last). Work-arounds in extreme cases include using a common USB mouse with the laptop.

If using older software/hardware

While not all issues have been resolved, especially when using older software/hardware from 2007 and earlier in 2008, three touchpad issues stood out:

The pointer jumps to the bottom-right corner of the screen

This can happen right after you touch the touchpad. Rebooting often helps (see <trac>2804</trac>).

The four-finger salute (Escape + Frame + Right Arrow + Fn, with Fn pressed last) usually fixes this.

The pointer moves around by itself

Instead of reliably following your finger, the pointer can move around on its own, sometimes when a hand is close to it. The four-finger salute (Escape + Frame + Right Arrow + Fn, with Fn pressed last) usually fixes this. Automatic recalibration on reboot may also fix the problem.

Mouse moves mostly vertically

If the touchpad works fine vertically but doesn't function horizontally (<trac>5575</trac>), it is likely due to damaged touchpad wiring. This was corrected and is very rarely seen in recently produced laptops.
