ABSTRACT:
An information handling system AC-to-DC adapter provides a low DC power output on initial application of an AC power input. The low DC power output supports communication between the adapter and the information handling system of adapter identification information. The information handling system confirms a proper connection with the adapter and sends an authorization to the adapter to output a high DC power output. The adapter monitors the connection with the information handling system to disable the high DC power output if not needed, such as if the information handling system is disconnected from the adapter or reaches a fully charged battery state.
