The ladyfriend has a 3 year old Powerbook that's managed to make it's way into my life. Decent enough machine for checking email and movie times from the couch except for one problem: the touchpad is totally hinky. Works fine about 50% of the time but it will often start jumping all over the place.
Any way to fix this? I'm guessing there's a short in there somewhere but I'm loathe to open the thing up and start tinkering around.
