Yesterday I was on facebook when my ibook g4 went black and turned off. There wasn't any beeping/flashing or anything but it won't turn on. When I press the little button on the battery 5 yellow lights light up so I guess the battery's fine but the laptop itself just died. If i can't get it fixed mum won't buy me a new one and i'll just have to deal with it, which i won't so please help me!
