Unfortunately Murphy’s Law struck this morning while trying to wake my powerbook up from sleeping. Last night I went to bed and everything was fine, but this morning the computer wouldn’t turn on.
After trying to diagnose the problem myself and failing–I decided to take it to an Apple Service Center. A quick inspection lead the technician to believe one of the following:
1) The power button was not working correctly and wouldn’t send the signal to boot to the logic board.
2) The logic board was fried.
3) The DC converter somehow wasn’t converting power correctly.
Basically when I press and hold the power button the hard drive begins to spin (I can hear it when I put my ear very close) but immediately fails. Like within the first second.
My question (I know, a tip site asking for help :)) is how would one start the computer directly from the logic board. I’ve tried to research this but no luck.
Here are a few more symptoms and things I’ve tried:
- Battery is fully charged, I confirmed this by pressing the button on the back of the battery
- I reset the PRAM
- I tried starting the computer from the logic board, but I don’t think I’m doing it in the right place
- AppleCare expired last year, along with my warranty when I replaced my LCD
I have a little experience taking the Powerbook apart–I’m just afraid it’s turned into an expensive paperweight.
I know this site has lots of experience Mac users, so what do you guys think? Time to throw in the towel and buy a new one or fight for the old G4?
