Abstract
An information handling system (IHS) includes a source load switch connected to a power management circuit, and a port for connection of a device. The IHS detects attachment of the device to the port, and determines whether the device is a current sink. When the device is a current sink, the IHS sets the peak processor power level to a reduced level, determines detachment of the device, and in response to determining detachment of the device, restores a maximum peak processor power level. When the device is not a current sink, the HIS starts charging, sets a dynamic peak processor power level to an AC+DC setting, determines detachment of the device, and in response to determining detachment of the device, sets the peak processor power level to a DC-only setting.
