Okay, I bought a Macbook about 2-3 months ago. I always leave it plugged in. However, once the battery charges, it slowly goes down from 100% charge - 99 -98 - 97... and so on. So 3 days after the battery has been charged (plugged in for the whole 3 days) the charge level reaches 94% and has to charge again. Then the process begins again. So my battery is slowly going through charge cycles, and it bothers me. It should run off of wall power when it's plugged in.... Any suggestions to fix the problem? Has anyone else had this problem?
