My PowerBook G4 1.5Ghz won't boot up. It happened about a year ago when I first got my new MBP so I just let it sit. But I'd like to give it to a friend if I can get it to work.

I've tried resetting the PMU by holding shift+control+option+power... waiting 5 seconds and powering on, but nothing happens.

The battery appears to be functioning correctly. When the cable is in it lights up like normal and the battery indicators light up and are in full charge.

I've taken the ram out and put it back in.

Any other clues what I could try before bringing it in to Apple?

Check the Airport Express card. I used to find that mine would become unseated if I took the battery out, and for some reason this would cause a big kerfuffle.

Do you feel comfortable with opening it up?
