Recently, I sent my 12-inch PBG4 to Apple to have them replace the Combo drive that had eaten a CD and refused to eject it. After I got it back (it was gone for just a day - great service!), it worked fine but I noticed it seemed to have a battery power leak problem. It worked fine when plugged in and seemed to charge normally. Now, however, it won't charge at all. I have it currently plugged in and its staying at 96% battery charge but it won't charge any further and the light on the plug is green (which would normally indicate a full battery). Any thoughts before I call up Apple and ship it back to them again?
