i have an ibook which just came out of warranty with a battery related problem. even though my battery is plugged into my computer, the 'energy saver' does not recognize its existence and instead states that there are 'no batteries available'. i have tried taking the battery in and out, and replugging the a/c adapter - after doing this, for about 5 minutes, the ibook will recognize the battery at 0% and 'calculating until full' Then it will immediately return to the 'no batteries available' status. I have already reset the PMU using shift-control-option-power with the same results. It will register the battery at 0% for a few minutes then go back to "no batteries available". The battery is only a year old and hasn't given me any other problems than the ones posted already - in which - when charging with the A/C adapter - it will only be 96 - 99% full and sometimes 100%. Please let me know what I should do. I don't know if this is related to the logic board problems I've been hearing about (I HOPE NOT - I only realized how possibly faulty my product could be after it came out of warranty) and would like this resolved as soon as possible. THANKS!
