I have a Toshiba Satellite P55w. The keyboard stopped working so I replaced it. Computer wouldn't turn on at all. Took it to a geek shop. They said no power at all. I myself replaced the motherboard. Now I get an white light but nothing else. I have tried to reset and pull out battery, paper clip, etc and still. I am not ready to give up damnit ... but what the help is it .??!??
