I plugged in my iBook G4 to charge a few minutes ago, and noticed it wasn't charging correctly. It would charge for a few seconds, then stop for a few, and resume charging again. At first, I thought it was the crappy charger I bought from eBay, but no, it's also a problem on the original charger (although I have gotten it to stop now on this one). I've pretty much accepted I'm screwed, or least that's what I'm assuming. But I want know, what is causing this, and how much will it cost to fix? Thanks.
