A computing device and method for remotely waking sleeping subsystems of the computing device are disclosed. The method includes monitoring a plurality of hardware subsystems on the computing device to detect when at least one of the hardware subsystems goes into an idle state and initiating a remote-start advertisement in response to the at least one of the hardware subsystems going into an idle state. A wireless low energy module of the computing device is monitored for a remote start signal from a remote device, and the at least one of the hardware subsystems that is in an idle state is powered up in response to receiving a remote start signal from a remote device. The remote-start advertisement is then ended in response to the at least one of the hardware subsystems powering up.
