The internal keyboard plugs into the VGA board via ribbon cable. The laptop won't post if the internal keyboard is plugged into the board (disks won't spin up, lcd stays dark, no beeps, nothing). Once I disconnect the internal keyboard the laptop will boot fine. I can disconnect the internal keyboard and use an external USB keyboard just fine, but that of course doesn't make for a very portable laptop.
Is this a symptom of a bad keyboard, bad VGA board, or something else?
