Claim:
1. A system, comprising: a power source integrated with a host computing device, and configured to provide power to the host computing device; a wireless power transmission module, coupled to the host computing device, configured to wirelessly transmit power derived from the power source, wherein the wireless power transmission module is to derive power from the power source during a plurality of operational states of the host computing device including a powered-off state; and a controller to control power transmission by the wireless power transmission module including terminate active power transmission by the wireless power transmission module when a time duration during which the wireless power transmission module is kept active exceeds a time duration threshold, and terminate active power transmission by the wireless power transmission module when a remaining power level of the power source is below a power level threshold, wherein, to terminate active power transmission, the controller is to determine whether or not a control signal is detected on a Universal Serial Bus connection between the wireless power transmission module and the host computing device.
