I have a Toshiba that wont turn on. It does not power up at all. No sounds, nothing spinning, beeping, nothing at all. When it's plugged in, the lights for AC and batt charging are lit, so it does have power. I have removed the battery and held the power button down, but still nothing. Any ideas? In my research so far, I have come up with the possibility that it's the power button board but I have no way to confirm this. Any help would be appreciated.
