Help!! Powerbook won't turn on.
I have a 1.25 Ghz 15 Inch powerbook. when i go to turn it on i can here the fan spin up for about 3 senonds and then nothing. As many times as i press the power buton it does this. I have tried removing thae battrie and using ac power only using battrie power only swapping out ram chips. Any one have any idea on why it is doing this?
