PowerBook Won't Charge Battery
I have a 15" Aluminum PowerBook 1.5 GHz PowerPC G4 running OSX 10.5.8
Recently the battery has stopped charging. In the menu bar I have a "not charging" next to the battery icon. I checked the battery with Coconut and it says the battery has a 79% capacity. I tried another batter from a friend since I thought that was the issue, but his battery was only 44% capacity according to Coconut. I tried his battery but it was also dead and didn't charge on my PowerBook at all.
I read about the DC board, and I'm hoping to get a new MacBook Pro when the Haswell chipset comes out, hopefully soon. I hate to spend $100 on a part for this laptop but is there any other option any one might see. I also read about resetting the PMU, which I've never heard of. Is this like zapping the pram? I remember that from my 8500 days.
Is this a good question?
