My year-old Powerbook G4 has acquired the habit of suddenly shutting off when it thinks it has no more power, which usually happens when the menubar item says the battery is around 30% full. Do I need a new battery? Or can I massage it into the proper sleeping/hibernating behavior somehow?

My iBook G4 has lately been winking out, for no apparent reason, as I'm in the middle of something (I have to reset the date each time, among other things). The weird thing is that it only seems to happen when I'm on battery power. When I press the little button on the bottom, it seems to indicate full power. However, I was noticing a month or so ago I was getting weird battery warnings -- saying it was almost out of power, when it said there was 41% power remaining, etc. Has anyone had this problem, and might a new battery somehow be the solution?
