Abstract
A power saving method for a peripheral device in a wireless operation mode is provided. The power saving method at least includes the steps of allowing the peripheral device to enter an idle mode and judging whether the peripheral device receives a startup trigger event. In the idle mode, the light source in an operation region of the peripheral device is in an on state or a high-brightness state. If the peripheral device receives the startup trigger event, the peripheral device is switched from the idle mode to a power saving mode. In the power saving mode, the light source in the operation region of the peripheral device is in an off state or a low-brightness state. The peripheral device in the power saving mode consumes less electric power than the peripheral device in the idle mode.
