Powerbook G4 powers on but won't boot

[nsawyerpdx]

Hi,

I have a powerbook G4 aluminum 1.25GHZ that was running OS 10.3. I updated it to 10.4, which worked fine, and then I was going through the process of installing the updates. While installing 10.4.3 I ran into a problem. When the computer was supposed to restart, it powered down, then powered up again, but it only gets as far as the white screen with the mac logo and sits there forever. Is this something that can be fixed or should I just start dismantling it and selling it for parts?

I recommend you archive and install, then use the combo updater:

You could try to repair permissions, repair disk, start in safe mode, etc, but an archive and install will only take ~ an hour, and there's lots of things that can cause your problem. Sometimes bootup after an update takes a while.
