Hey. I own a POwerbook g4 and i love it. One problem is the battery. Its always messin me about. Sometimes the laptop says that its fully charged and irts not even charged at all. At the moment, the battery wont even charge. Well the red light glows on the charger but the battery doesnt charge (through looking at the light on the battery, its always really low) and on some occasions it just says that there is not battery available. ve tried the usuals like taking the battery out and putting it back in properly. Ive tried charging it in sleep and **** down mode and still it doesnt work. Any ideas on the problem or how to fix it? Cheers.
