Q: I have a PB G4 that won't start. It shows the gray apple screen, shows the blue screen, and then the screen goes black, and "sleep" light pulses.
I have a PB G4 that won't start. It shows the gray apple screen, shows the blue screen, and then goes black. The sleep light pulses. From there, I can't turn it off normally. I have tried restarting the PMU. And I have tried unplugging the ac adaptor and removing the battery. From there I have plugged only the ac adaptor in, and it will begin to start but do the same thing once it shows the blue screen.
I tried only using the battery (without plugging in the ac adaptor) and the same thing happens. I tried starting the computer while holding down CTRL, Option, P, and R, waiting to hear the start up chimes 3 times, and then holding Shift as it starts up. But I still get the black screen once I see the blue one, and the computer's sleep light pulses.
I need something very important from this computer. And was able to start it last night. I did not shut down the computer, and was going to take it to a friends to use his printer today. The computer was in sleep mode in the morning.
Thanks for any help!
