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, device and computer. The method includes: detecting whether the computer has abnormal power-off; resetting CMOS, and the reset signal comes from an external circuit including a power chip. According to the technical solution of the embodiment of the present invention, when it is detected that the computer is abnormally powered off, it receives a signal sent by an external circuit to reset the CMOS on the computer motherboard to reset the CMOS, and the external circuit includes a power chip , which can avoid the risk of failure to send reset CMOS signal due to sudden power failure when EC detects abnormal power failure.

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 ...
