Yes, this actually happened to me. My wife's powerbook and my iBook died Friday. I believe the Powerbook's HD crashed. As for the iBook: Its a 1.2 ghz PowerPC g4 with 768 Ram. For some reason, the computer runs all day when its stable and on my desk. Once I move it, the screen will go blank and its obvious the computer is on. But the screen is a black with everything locked up. When I power down, let it sit and start it up, it works again, only until you move it. You can imagine how frustrating this is. Its completely updated to the lastest version of 10.4. Any ideas? Help? Will Apple help me? Onto the Powerbook: I heard some clicking. It sounded like a harddrive problem. I turned it on, it went right to a black screen which looks very similar to a DOS command screen. It says "Computer's Name Powerbook" or something like that on a command line. It just stalls at this screen. My concern is this..are both computers dead? I'm in summer session and NEED a computer. So I have to act fast. What can I do? Thanks for ANY help.
