Abstract
The invention discloses an electronic device and a power management method thereof. The method comprises the following steps that: a control unit receives a power output signal of a set of peripheral equipment; the control unit detects whether an information transmission signal is input into the control unit from the peripheral equipment every other fixed time; if no information transmission signal is input into the control unit from the peripheral equipment, the control unit controls a timer to start to time; when a timed value is greater than a first preset value, the control unit sends a first control signal to an operating system of the electronic device, and displays an idling state of the peripheral equipment on a user interface; and when the timed value is greater than a second preset value, the control unit sends a second control signal to a power control unit, and cuts off the power supplied to the peripheral equipment. According to the power management method, the energy consumption of the electronic device can be reduced.
