Hi, I'm a new convert to Macs and I'm loving it so far. Bought the Penryn Macbook Pro back in March. Everything has been fine except I'm noticing the battery meter is acting weird. I have drained it to single digit and then charge it back up again several times since I got the machine. It will usually charge back up to 100% for a few days and then slowly trickle down to 98% and then 97%. I just unplugged it this morning and it's not been 15 minutes and it's already down to 91%!! I use it mostly at home so it's plugged in most of the time. I'm not using it for anything heavy duty right now. Am I in trouble with the battery? Thanks for the help.
