I don't understand what is occuring. Mine goes for about 3h30-4h00, with low backlight. Maybe your battery is badly calibrated Note also that USB devices consume a lot of energy, even when sleeping : my ibook can't pass the night sleeping with an usb mouse, and stand 3 or 4 days without. > >I've tried using pmud and apmd, and both had the same behavior (though >pmud actually suspends-on-close whereas apmd didn't). You should not use apmd.
