Abstract

The invention relates to an energy-saving electric device, wherein it comprises: a processor, a power manager, an input terminal, and a controller; the controller can receive the input signal of inputterminal to communicate with the processor, to inform it into sleep state and generate one control signal to the power manager, to control the power manger to close or connect the power of processor.And the relative method comprises: the controller receives the input signal of input terminal to inform the processor ready for sleeping; when the processor is ready to sleep, it feeds back one statesignal to the controller; the controller controls the power manager to close the power of processor. The invention can eliminate the power consumption when the processor is sleeping.

Description

【Technical field】 [0001] The invention relates to a power-saving electronic device and a power-saving method thereof, in particular to a power-saving electronic device and a power-saving method for saving power in a sleep mode. 【Background technique】 [0002] like figure 1 As shown, an electronic device 1 , such as a CD player, a portable computer, a desktop computer, etc., includes an input terminal 10 , a processing unit 12 , a power management device 14 , and a display device 16 . Wherein, the processing unit 12 is used to execute the core functions of the electronic equipment, which may be a decoding servo chip of an optical disc player, a central processing unit of a computer, and the like. The power management device 14 is configured to perform power management functions of the electronic device 1 , such as turning on and off the power of specific electronic components. In order to reduce unnecessary power consumption, most of the existing power management devices 14...
