Embodiment Construction

[0037] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0038] During the use of the computer, sometimes the following situations exist: In the power-on mode, the power adapter and the battery are removed at the same time. In this case, in order to prevent the clock (Real-Time Clock, RTC) from being damaged, it is necessary to cut off the RSMRST# signal of each device before the voltage of each device powered by the power supply exceeds the preset normal operating range. That is to say, before the power supply voltage of the south bridge is lower than the preset value, the RSMRST# signal of the south bridge is cut off. figure 1 It is a schematic diagram of the RSMRST# signal and its corresponding power signal VCCPRIM when an a...

Abstract

The invention discloses a power-off protection method, a device and a computer. The method includes the steps: detecting whether the computer exists abnormal power-off conditions or not; resetting a CMOS (complementary metal oxide semiconductor), and enabling reset signals to be from an external circuit comprising a power supply chip. According to the power-off protection method, when the computer exists abnormal power-off conditions, the reset CMOS on a computer motherboard transmitted by the external circuit is received, and signals of the CMOS are reset, and the external circuit comprises the power supply chip, so that risks of failure transmitting the reset CMOS signals caused by sudden power off are avoided when an EC (electronic computer) detects abnormal power-off conditions.

Description

technical field [0001] The invention relates to the technical field of power-off protection, in particular to a power-off protection method, device and computer. Background technique [0002] During the use of the computer, sometimes there is an abnormal power failure: for example, when the laptop is in the power-on mode, the power adapter and the battery are removed at the same time. In this case, it often causes the failure of the system to boot normally. [0003] In the prior art, when such a fault occurs, the fault can be eliminated by resetting the Complementary Metal Oxide Semiconductor (CMOS). However, during the process before and after resetting the CMOS, the computer needs to be disassembled and assembled. Since the parts of the computer are very precise and complex, it is easy to lose parts or assemble wrongly during the assembly process. Contents of the invention [0004] In view of this, the purpose of the embodiments of the present invention is to provide ...
