Abstract:
1. An information handling system having power supply shutdown control, said system comprising: an information handling system having a power supply, the power supply adapted for receiving power from an external power source and providing voltages necessary to power the information handling system, the power supply having an on-input and an inhibit-input, wherein the on-input is used to turn the power supply on and off and the inhibit-input prevents the power supply from being turned on when at a first logic level and allows the power supply to be turned on when at a second logic level; and a shutdown control circuit monitoring at least one voltage from the power supply, the shutdown control circuit having an output coupled to the inhibit-input of the power supply, wherein when the at least one voltage is less than a first voltage value the shutdown control circuit output is set to the first logic level, and when the at least one voltage is less than a second voltage value the shutdown control circuit output is reset to the second logic level.
