Laptop touchpad jumping mouse

[Oona]

Hello people

Have Fujitsu Siemens Amilo Pro laptop with built in touchpad. Unfortunately
the mouse jumps around while I'm in the middle of typing. It has done this
ever since it was new. It isn't always because I touch it. Advanced text
services are off already. The mouse driver doesn't allow sensitivity to be
adjusted, or even tap clicks to be disabled (no, it really doesn't). Have
tried installing different mouse driver from manufacturers website, also
doing updates from microsoft update. To my knowledge I haven't damaged the
touchpad. Suggestions??

If placing a piece of cardboard over the touchpad cures it, then
touching is the issue. If not, then i would suspect defective hardware,
and ask for the unit to be replaced.
