ever since I did the battery update, my battery has been draining really fast. Today for instance, I unplugged it for the first time in a long time (I usually keep it plugged in an hooked up to an external monitor). I unplugged it, opened it up, sat on my couch and looked at the battery meter, it was at 82%. WTF is that?!?! why does the battery not keep its charge anymore? I only bought the computer in Feb. and according to iStat, there is only 44 cycles on it! Anyone know what is going on? or what I should do?
