New to the forum, and hate to come in and ask a question. But my Powerbook will NOT turn on, if i hold the power button briefly and turn it on, the sleep light will turn on and then blink slowly. If I hold the button down, to turn it on, the fan will kick on, and the sleep light will flashy constantly, then turn off, and dies. The screen doesnt even hit the apple logo. Anyone have any clues as to how to fix this problem...I love Mac, but boy have i had many problems with my pb. Thanks ahead of time.
