I have a Sony TZ 150 (Model PCG 41L) with win xp, service pack 3 and having problems with the Alps touch pad - it seems to just stop responding and mostly, I have to re-boot the system

I checked with SOny and the driver seems to be up tp date (Device Driver says the Alps pointing Device is working) but I think this is either a hardware issue or a Windows issue.

In what may be a related issue, my cursor keeps jumping around the screen when typing - I have no idea why.

Help!!!

Could be just a bad touchpad. You can try to update the BIOS for the system since you already checked the driver. If that does not work, you can find a used touchpad online, probably easiest to get the whole palmrest assembly.

The jumping cursor when typing is 95% of the time someone hitting the touchpad with their hands while typing (with the palm or something). The other 5% it's faulty hardware.
