I have a quick question about the MacBook batteries so I'm hoping somebody can help me out! Anyways tomorrow I'm going to look (and possibly buy) a Black Core 2 Duo MacBook and the girl who is selling it told me the battery doesn't work. Now normally this would be as simple as buying a new battery but it could also be something as big as the logic board, which I don't want to deal with. Is there a certain way to tell if the battery is just dead or the logic board has to be replaced? She is selling it for $200 so it's a good deal, I'd just rather not buy a computer I can't move around with me so a battery that charges is a must. Thanks.
