Ibook trackpad issue...
OK, here's the deal. My brother-in-law has an ibook 500mhz--dual-usb, you know the drill. He called me and told me that his trackpad is acting up--it was just shooting to the left for no apparent reason, and it was clicking on things. We figured out the clicking--it was just a Sys Prefs setting issue--but the erratic cursor behavior still goes on. Apple discussions suggested resetting the PMU--which we did. The process they named didn't even reset the PMU (Date and Time stayed the same, etc.) Here are my questions:
1) Does the Apple instruction on resetting the PMU hold water, or is there another way, and
2) Does anyone here have experience with the erratic trackpad problem, and how do you fix it?
I--and my brother-in-law--will greatly appreciate any assistance that can be given.
Thanks everybody!
