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 PCI-Express adapters) installed (embedded
video on some models only) and a single monitor, the monitor must be plugged into the monitor
connector on the source selected as the primary VGA adapter. During boot, the other monitor connectors
are disabled and if the monitor is connected into these ports, the monitor will not function. You can
select which source will be the default VGA source in Computer 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.

Solving general problems

are unable to resolve it yourself or if you feel uncomfortable about performing the operation, contact an
authorized dealer or reseller.

IMPORTANT:

When the computer is plugged into an AC power source, voltage is always applied to

the system board. To reduce the risk of personal injury from electrical shock and/or hot surfaces, be sure to
disconnect the power cord from the wall outlet and allow the internal system components to cool before
