Abstract
A power adapter device including a power supply and a power delivery integrated circuit (PD IC). The power supply provides a current to an output terminal of the power adapter device. The PD IC initiates a first voltage across a first resistor of a first information handling system. The PD IC monitors a second voltage at a voltage pin of a power cable. The power cable is connected between the power adapter device and the first information handling system. The PD IC compares the second voltage at the voltage pin to a threshold voltage level. In response to the second voltage being greater than the threshold voltage level, the PD IC performs a power adapter fault operation.
