So I got a Macbook C2D 2.1ghz, 1gb ram.. The issue with the macbook is it wont charge a batter but neigher will it run off the charger.. So basically only time the macbook can be used is when the battery has charge in it.. I tried replacing the DC in board, battery connector.. SMC reset. No luck so that leaves the logic board. My question is there some sort of solution perhaps that others have found that could make this macbook still useable? Like having some sort of external charger plugged into the battery while using it to keep the battery always topped off?? As the macbook will run fine as long as the battery has charge. Please anyone have any ideas? Otherwise I dont know what to really do with this mac as a logic board is a bit too $$. Thanks!
