Problems solved by technology

[0004] However, although Chinese mainland patent application No. 200610123166.8 can reduce the battery power consumption when the electronic device is off, that is, it is equivalent to prolonging the power storage time of the battery, it cannot completely avoid the battery power consumption when the electronic device is off. If the electronic device is turned off for too long, the power in the battery will be exhausted, and it may not be able to turn on the device

Abstract

The invention provides a power-saving circuit of an electronic device. The power-saving circuit is connected between a battery and a main frame and comprises a triggering end which receives an external triggering signal; the triggering end is electrically connected to a switch unit, and the switch unit comprises a control end, a battery end and a main frame end, wherein the control end is electrically connected to the triggering end, the battery end is electrically connected to the battery, and the main frame end is electrically connected to the main frame. Before the triggering end receives the triggering signal, the battery end and the main frame end are in the switching-off state; after the triggering end receives the triggering signal, the battery end and the main frame end turn into the switching-on state from the switching-off state. Before the electronic device leaves a factory, the battery end and the main frame end maintain the switching-off state, the battery does not consume electricity in the subsequent conveying process, and even if undergoing a very long period of time, the battery still maintains the original electric quantity for initial use.

Description

【Technical field】 [0001] The invention relates to a power-saving circuit of an electronic device, in particular to a power-saving circuit of an electronic device that no longer consumes power in a shutdown state. 【Background technique】 [0002] With the advent of the information age, electronic devices have become one of the main tools for people to obtain information. Among them, notebook computers are not only the most frequently chosen commodity by consumers, but also a market product that manufacturers are committed to developing to make them more perfect. When the computer is assembled and ready to be shipped, the manufacturer will charge the battery of the notebook computer to a half-saturated state and install it in the notebook computer. However, the notebook computer will still consume 5mA to 8mA of power when it is turned off. When the electronic device is turned off, the keyboard control unit will still consume power, although the keyboard control unit can enter t...
