Hello, I have a one year old, 1.83 GHz macbook that has been having some weird battery problems. Earlier this week I was doing some writing, having just upgraded to leopard, when I looked over at the battery icon; it said 20% remaining. 5 minutes later my computer went to sleep. I charged it up and to my surprise the battery had changed to 0%. I clicked dashboard and looked at iStat Pro. It said that I only had 56% battery health, whereas the day before it said that my battery was 100% healthy! I then turned off my macbook and charged it up to full. When I restarted it in the morning everything went back to normal, with the battery at 100% health and everything. I have been having this sort of thing happen almost every day now and it is really irritating. I hope that you guys can help me because it is really irritating to not know how much charge my battery has, and since my warranty is up there is no one who can help me. Oh, if it helps, my battery has had about 239 load cycles, and this has never happened before I upgraded to leopard.
