My iBook has picked up a distressing habit here in Paris. Whereas it lasted three or more hours on the battery prior to last week, it now only goes for about forty minutes to an hour. I haven't modified any of the Energy Saver settings or changed my usage pattern at all. The battery says it's fine, getting down to about 65% full and then it just sleeps. When I plug it in and wake it up, it says the battery is at 0% (and charging slow as hell). I guess a trip to the Apple store is in order when I get to NYC because a laptop that's not portable is just a paperweight.
Update: I reset the Power Manager as several people suggested. No dice.
