i got an ibook 700mhz the battery meter right with full charge if i unplug it says about two hours...and it goes down regularly, but then at about the 1 hour mark my screen goes blank and my computer goes into sleep...it won't go out of sleep until i plug it in and close it and open it back up...and then it immediatly says theres only like 2 mins of battery life left!! anyone know whats up?? my battery used to work fine...got a little over three hours and if i ever got it down to like 5 mins left then it would go into sleep mode. i've been keeping it plugged in a lot in the last month or so. and it just started doing this and now it always does. anyway, i probably didn't do the best job of explaining the problem...but i hope someone can help.
