    Abstract: In one example, an electronic device may include a power source to supply power to a peripheral device, a sensor circuit to monitor a power consumption of the peripheral device, and a controller coupled to the sensor circuit to detect that the power consumption of the peripheral device is greater than a threshold and generate a popup message on a user interface of the electronic device based on the detection. The popup message may include an option. Further, the controller may direct the power source to continue to provide the power to the peripheral device in response to a determination that the option is selected prior to an expiration of a timer.
