Power and Cooling Problems

If the power indicator does not turn on when the power cord is plugged in,
you may have a problem with the power outlet, power cord, or internal
power supply. However, if the unit powers off after running for a while,
check for loose power connections, power losses or surges at the power
outlet, and verify that the fans on the unit are unobstructed and running
prior to shutdown. If you still cannot isolate the problem, the internal
power supply may be defective.
