Hello all! I have an ibook G4, with tiger installed on it. My battery is horrible, it barely holds any charge anymore. I was using the computer, when my charger plug slipped out. I didn't notice it, and the computer shut off. I turned it back on again, but the same exact thing happened, and it shut off as soon as it had booted back up. Now, when I try to turn it on, I get a screen with an Apple logo and nothing else, and it does not change no matter how much I wait. Any ideas on how I can get this fixed?
