If you have installed an operating system other than the
factory-installed operating system, check to be sure that it is
supported on the system.

If the system has multiple video sources (embedded, PCI, or AGP
adapters) installed (embedded video on select models only) and a
single monitor, the monitor must be plugged into the monitor
connector on the source selected as the primary VGA adapter.

source in Computer (F10) Setup.

CAUTION:
When the computer is plugged into an AC power source,
there is always voltage applied to the system board. You must disconnect
the power cord from the power source before opening the computer to
prevent system board or component damage.
