Tried to charge a phone battery with a USB cable plugged to my Toshiba e45tt b4300. I think I placed the red wire to the + and the blue to the - on the battery. After plugging in the USB. The computer went down. Can't start it up anymore. Did I kill the motherboard? When I turn on the laptop I see the led on but the fan is not running. Nothing on the display. Did the phone battery kill the laptop?
