Abstract: Power delivery may be controlled to help prevent arcing when a data cable supplying power from a power source device to a power sink device is disconnected. The presence of a user in proximity to a connection between a cable plug and a cable receptacle may be detected. The level of a power signal being conveyed from the power source to the power sink may be reduced in response to the detection.
