im hoping someone can help me out with this problem i am having. i have a 12inch pbook rev A and theres something wrong with the battery or battery meter. When the pbook is fully charged the meter will drop down at a normal rate to around 55 % and then the computer will just shut off as if the battery is dead. If i then plug it in to charge it it says that the battery is at 0 %. i am only getting somewhere around an hour until the meter drops down to around 55% and shuts off. anyone have any help to offer me? please.
