I just got the following message from a friend:
"My iBook wouldn't turn on today, and now it's doing weird stuff. The screen is on, and then it just blacks out. When I restart it, I have to try several times because it makes a huge whirring sound. I wonder if the screen has somehow...burned out? If that's the case, though, then tell me why the computer itself has trouble starting. It's not plugged into the wall at the moment, but that shouldn't be a problem since the battery power is fine. I really can't associate this problem with any specific event, either."
Actually, that was sort of a paraphrase of my conversation with her.
In any case, does anyone have any ideas?
P.S. This was priceless: "I'm wondering if it has to do with that...what do they say...the blue screen of death?"
Update: "You know when you turn the display all the way off on the keyboard? It's doing something similar to that: The display is still 'on,' but it's all black...and it sort of flickers before it does so."
