Hey guys, The computer is almost 2 years old, stil works great except for a small battery problem. If I'm running off of battery, when it gets down to around 25%, sometimes the computer will just hibernate. When i plug it in, the battery meter reads 0%. What gives? Its doesn't happen all of the time, but more frequently recently. When I am using the computer just off of AC at my home, I usually remove the battery, so Im not sure if its the battery itself. Then again it is two years old. Recommendations anyone? Is this covered under apple care?
