reseat the power cable at the power source.
Turn the switch to the off position, connect
the power cable to another power source, if
available, and turn the switch back on.
Turn the switch to the off position, remove
the cable and replace it.
If the system still fails to come up when the
power supply is connected to a different
power source with a new power cable, the
power supply unit is probably faulty.
Contact a service representative.
