A couple of months ago the logic board on my iBook G3 800 just died - like they apparently do sometimes. Understanding that this is the way of things, I got it repaired under Apple's logic board replacement scheme, nice and easy, at no cost to me. Great. The only thing is, ever since it came back from logic board hospital strange things have been happening, usually connected to sending it to sleep or waking it up. It now wakes and sleeps at random moments, quite often refuses to come back to life after being asleep, and once OS X just disappeared completely and the was replaced by a blinking cursor on a black screen - very 1994 MS-DOS, but not great in 2005. In addition, the processor seems to have slowed up a lot recently (unconnected I think) as I can't seem to play Stick Cricket as smoothly as I used to... All in all I'm starting to think the poor thing just wants a rest and is trying to convince me to buy a new iMac and put the iBook into semi-retirement. In the hope of saving me a grand, anyone have any ideas what it going on?
