I have a 2008 Macbook and when the power is plugged in, the light is green, however my battery will not charge, and it even says at the top "battery is not charging" If I remove the power cord from the computer it will still run off the remaining % of the battery, but If I reconnect the cord it lights up green and I never see the amber charging color. I traded out my battery as well as a different cord and still the same results. My battery will charge up on a friends macbook, but not on my own. I want to take it to the apple store but I'm at school and there is no store near me. Any ideas on what might be the problem?
