I got my logic board replaced. I took my iBook to an Apple store last Friday and it came back on Tuesday. The Apple genius took my sick iBook with no problem. Fast service & minimum down time. With my extended warranty just mailed, I feel good about keeping this machine for another two years - at least. Apple also did a real good job cleaning the keyboard and screen. I'm a happy camper again - thanks Apple. Jim 12" iBook 700/640/20/CD (2002)
