I recently upgraded my ibook to system 10 "Tiger" and have been having problems. It had been working well, but then last week started to crash and wouldn't boot; I was able to get it going again by starting up from the system disk a few days ago and ran disk utility, etc. but today it shut down again and the screen has gone completely dark. I can hear the startup noises but have no idea what is going on because the screen won't come up. Does anyone know any trick for getting it to wakeup the screen? Or have any other insight?
THanks

It may be just a coincidence that you recently installed ox 10.4. I have gone through two logic boards on my ibook, and my third one is running fine. Apparently apple had a lot of problems with iBook logic boards, as the other iBook in the house crapped out on us too. So apple has replaced three iBook logic boards for us in the past year.
Of course they did it for free because we had applecare, but those symptoms you are describing...
1. Crashes/shuts down for no reason.
2. Just get a blank screen and start up noises.
3. Sometimes when I would start mine up the fans would go on full blast while the screen stayed dark.
Anyway, just thought you might want to consider that your logic board crapped out on you. It's very possible.
