Since I bought my refurbished Apple PowerBook G4 a few months back, I've been plagued by a sticking trackpad button. It would occasionally crunch, not respond to clicks, and or do other odd things. Previous trips to the Genius Bar at the local Apple Store resulted in a diagnosis of a loose screw in the trackpad assembly, and getting it tightened up.

After bringing it in for the 3rd time, the folks at the Genius Bar determined the contacts on the trackpad button itself were sticking. The extra force I guess was causing the screws to come loose. So Monday, I took it in for a new "Top Unit" (which contains new keyboard, etc.). I was happy about this since I had always been experiencing intermittent keypress drops on my keyboard as well....

I got the unit back. Ahhhhh.....I love having a working trackpad button. And, the keyboard is definitely more responsive now.

Would have been perfect had they not given me a heart attack when I noticed the system only has 1GB of RAM instead of 1.5GB. Turns out the 512MB module wasn't fully seated. Fixed that up in a jiffy, but....

Thanks to Apple nonetheless for good customer service and doing the right thing by replacing the defective part instead of repeatedly applying band-aids....
