It`s totaly dead. No reaction on power-on button. Then, after some time I push the power button and it starts.Works normaly until I turn of laptop.When I press power button again it don`t start at all. Dead as a brick.
You think that defect GO7600 can stop laptop to turn on at all from time to time? I dont mean Black screan. I mean not working at all.
