I've had this MacBook since April (this year). It's never been dropped, damaged or had any other problems (apart from a dead pixel which I can live with). Just booted it up a few minutes ago and it says, next to the battery icon, "Not Charging". I've done a Google search and searched these forums but I haven't come up with any solution. I've tried taking the battery out and replacing it again, no joy. Is the battery dead? If not, how can I fix this?
