How long do your 15 1st ed al powerbooks last when unplugged from the wall. The 14 ibooks and 12 powerbooks get like 4 hours and i'm lucky if i can get like 2-2.5 hours on mine. Do you think that my battery is bad or do they just equip weaker batteries on the 15. I have all the powersaving features on and have the screen as dim as it will go.
Thanks,
Stephen
