POWER-SAVING CIRCUIT FOR COMPUTER

摘要

A power-saving circuit for a computer that includes a host and a monitor, the power-saving circuit includes a sensing module and a control module. The sensing module is configured to detect whether an external object in vicinity of the monitor is absent from the vicinity of the monitor, and output a corresponding detecting signal in response to detecting that the external object is absent. The control module includes a controller electronically coupled to the sensing module, the host and the monitor. The controller is configured to calculate a time period of the absence of the external object according to the detecting signal, and control the host and monitor to proceed into different power modes according to the time period.
