iBook G4 12" won't power on at all!
My iBook G4 (1.33 GHz) won't turn on/power up no matter what I do. The computer was on and "awake" about a month ago, and then blanked out at some point one morning--and I did not see exactly what happened to it. Since then, the computer won't turn on no matter what I do. When I push down on the power button, nothing happens. The battery is fully charged (four green pips). Since this happened, I've tried taking the battery out overnight and putting it back in, and I've also tried also the various PRAM reset combinations on the keyboard. Nothing works! Although this is a backup computer, I'd like to get it working again if at all possible. Hope someone here can suggest how to troubleshoot the problem, and suggest a fix. I have installed the AirPort Extreme card and RAM into the laptop a few years ago, but I've never done anything more involved.
