Under 10.2.4 through 10.2.6 I had at least 3 hours of battery time. I then installed Panther and still had 3 hours of battery time. I formatted my HD to get rid of Panther because I didn't support Bluetooth, and now I only get 1.5 hours or 2 hours if I'm lucky. I've reset the PMU and drained my batteries until my computer shutdown, and recharged while the computer was off, and still I can't get back to 3 hours. Whats up with that! I've been keeping the dimmness low and the CPU using low power. Any thoughts? Could Panther Final fix it?
