View Full Version : PowerBook won't turn on!

Jun 28, 2011, 11:17 AM
Hi, I have a 12 inch, 1.5 GHz PowerBook G4 that is having problems. I
shut it down as the bluetooth wasn't being recognized, and when I turned it on, it didn't chime or give anything onscreen. What the heck is wrong? I've tried a pram reset, pmu, tried going into open firmware, and it won't eject any discs with the mouse down. Any input is appreciated!

Bad RAM maybe? Try removing the battery or other external devices.

Tried it without the ram in, no dice. It turns on, I can hear fans spinning and the optical drive working, but nothing else. I've also tried it with an external monitor, that didn't work either. :(

It defiantly wouldn't work without the ram in! I meant to try different sticks of ram. :o

Maybe try removing the PRAM battery if you can get to it.

I do not believe the 12 inch model has a PRAM battery. There is a very short-term capacitor that keeps the time and date for about 15 seconds between battery changes.
