ABSTRACT:
An information handling system (IHS) employs a power fault protection circuit to protect the IHS from overvoltages which may occur on an information line from a power adapter to the IHS. The system includes a processor coupled to the protection circuit. The circuit is operative in a first mode to decouple an information line from the IHS in response to a disable command and operative in a second mode to decouple the information line from the IHS when a voltage in the information line exceeds a predetermined threshold voltage.
