Hello, I have a MacBook 13 inch Unibody, late 2008. I had an issue with the battery for the last 6 months, it degraded to 55% health it says and it is a little bit swollen. but it still worked... I was very careful not to leave it unsupervised and powered or charging. Other then that it was ok and i had already ordered a new one. But before the new one arrived, my magsafe adapter cord ripped. ... right at the exit from the adapter. It weakened and then, my mac just shut down... I disconnected it and didn't use it until a bought a new MagSafe adapter. but now comes the real problem. With the NEW magsafe adapter, the Magsafe Plug Led is a dim green and my Mac DOESN'T start without a battery. It starts with a battery and if i remove the battery after boot it works just fine just with the adapter. The OS reports that battery is NOT charging when connected. I read online that the MagSafe board (the little board with the plug might be fried), so i bought a new one and changed it. It happens the EXACT same thing with either one. I started to suspect the new adapter. I borrowed another good adapter and tried it. It happens the EXACT same thing with either adapter. I ran an Apple Service Diagnostic and the MacBook Passed it without any problem. I ran an Apple Battery and Adapter Diagnostic. It said: Replace battery, Adapter Connected, Battery NOT charging. And now the cool thing. The battery IS ACTUALLY charging. When all this business started it was at 66% charge, and after all these tests it got to 90% now. So actually the only things that are amiss are: the MESSAGE that the battery is not charging because it IS charging in fact. The Dim Green Light on the adapter plug. And the nasty part is that the macbook is not starting without a battery. I off course suspect the logic board. My question to you fine gentlemen: Do you think it could be something fixable WITHOUT changing the Logic Board?
