Have a Toshiba satellite c75-c7130 push power button and it stays on for about 5 secs. Then goes back off without any thing else coming on. Did the battery out and sit not coming on.Did the plug in after then the battery back in.same t. It won't stay on long enough to let the pc boot. I get the same blinking light 3 Times if you hold the power button down for a little while.
