I have an ibook G3 that will not turn on. I'm not sure, but I think it's because long ago, the wire in the charger I had split open and it started sparking up by where you plug in the power supply. I got a new charger from a friend and the other night, that mysteriously stopped working. So my computer was at 0% (the battery) and I closed it, and when I opened it again, it wouldn't start up, and still won't. I don't know if it's burned out or what...I tried to plug in my father's charger which works..and start it up. But it still won't come on. So please, if anyone knows anything I can do, please reply.
