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?

I have a new 12 inch PowerBook with original power adaptor, my girlfriend has a 1 year old iBook with original power adaptor, I also have an old 15 inch 877 MHz "TiBook" PowerBook with an aftermarket power adaptor supposedly built just for that TiBook (at least I was told it would work with that TiBook.) Can we share power adaptors? Or should I only use my new power adaptor with my new PowerBook?
