I bought my iBook refurbished from techrestore for about $550. Great deal right? Well, apple told me the iBook was about 3 years old, and the battery lasts about 2.5 hours. So i bought a new one. It arrived deffective. Thanks ebay. After much research and a little help from my local batterymart(no help from apple) i realized the battery had been left dead and unused for too long. So i got it to last me about 3 hours then it quit. now it will last me about that long but it will only charge when the iBook is open and only spuratically and it will only go to 43%. ive tried reseting the PMU and pretty much everything else. please help a noobie out.
