    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.

    Abstract translation: 本文讨论的实施例涉及用于在待机或睡眠模式下控制计算设备的功率消耗的系统，方法和装置。 在待机或睡眠模式期间，可以将外部设备插入计算设备。 外部设备可以从备用电源提供电力，直到确定主电源是否正在运行。 该确定可以基于将主电源的输出与备用电源的输出进行比较。 如果主电源正在运行，计算设备中的一个开关可以关闭，以允许主电源向外部设备供电。 此外，在一些实施例中，开关仅基于来自备用电源的外部设备的当前需求而关闭。
