Good afternoon! Could you help me with this MacBook Pro A1286 that isn't displaying video? Its motherboard is marked with the following number: 820-2850-A. The laptop turns on with its external power button and the fans work normally, but there's no video output. To shut it down, I press and hold the power button for about 7 seconds. I've attached the old BIOS file. Thank you.
