Abstract: The embodiments discussed herein relate to systems, methods, and apparatus for controlling power consumption of a computing device in a standby or sleep mode. During the standby or sleep mode an external device can be plugged into the computing device. The external device can be provided power from a standby power supply until a determination is made as to whether a main power supply is operating. The determination can be based on comparing the output of the main power supply to an output of the standby power supply. If the main power supply is operating, a switch in the computing device can close to allow the main power supply to provide power to the external device. Moreover, in some embodiments, the switch can close based exclusively on a current demand of the external device from the standby power supply.
