ABSTRACT:
A computer system is disclosed. The computer system includes a core processor, a power supply including a first output in power communication with the core processor, and a power switch in signal communication with the power supply for controlling a state of the first output. The computer system also includes a service processor in signal communication with the sub-system and power communication with a second output of the power supply and a back up power supply. In response to activation of the power switch and a fault of the second output, the service processor uses the back up power supply and a reduced power mode to detect the fault of the second output and generate a signal representative thereof to be displayed upon a light emitting diode display.
