Powers on and outputs a display. Does NOT include HDD. Could not get any further than POST due to keyboard error when using AT keyboard. Possible clock battery issue might be the reasoning behind the port not functioning correctly. It is a well known leaky battery which happens to be right next to the AT keyboard port.
