Solving General Problems
You may be able to easily resolve the general problems described in this section. If a problem persists
and you are unable to resolve it yourself or if you feel uncomfortable about performing the operation,
contact an authorized dealer or reseller.
WARNING! 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 touching.
