I'm trying to help my father fix an ailing iBook (late 2003). Here's the skinny:
The machine seems to want to run ENTIRELY off the battery and not off the power supply, and so it'll shut down as soon as the battery runs out of juice.
Here's what's weird: The battery indicator in the menu bar says it's charging. The light on the power adapter is green. Zapping the PRAM didn't help. Resetting the PMU didn't help. Hardware test came back good.
The machine will NOT boot without the battery and when plugged in. We've tried other power adapters from other iBooks, and they don't help.
Here's what's even weirder: The machine seems to charge the battery. It just won't power itself off of the power adapter.
Any ideas/help?
To make matters worse, we think the thing is ONE WEEK out of warranty.
Thanks in advance for any help.
Cheers
Scott
