I have had my macbook pro since may 2007 and until the last few months, my battery life is about a half an hour on a full charge. I have unplugged it and let it die and then recharged it from the off position as I was told to do this buy mac store employee. This did nothing. My istat pro stats for the battery is health 18%, cycles-38 and charge of 100%. Any suggestions on how to get the battery back to normal.
