Problems solved by technology

[0002] During the research and development of computers (including desktop computers and notebook computers) or consumer use stages, system crashes often occur. At this time, it is often impossible to accurately determine whether the specific situation is due to hardware crashes or software crashes, so that it is difficult to solve the crash problem. There is a deviation in the general dire

Embodiment Construction

[0038] In order to enable those skilled in the art to better understand the present invention, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] A kind of computer fault detection method of the embodiment of the present invention, such as figure 1 and Figure 4 shown, combined with Figure 5 , including the following steps:

[0040] S1, send the system management interrupt signal to the processor 4 of the computer, the processor 4 enters the system management mode (SMM) after receiving the system management interrupt signal (SMI), the system management mode is independent of the operating system of the computer, and this mode is for the computer The operating system is transparent and does not depend on the operating system. Therefore, in this mode, the processor 4 can still perform other operations when the operating system and its software fail to run due to failure.

[0041] S2, the processor ...

Abstract

The invention discloses a computer breakdown detecting method and device. The method comprises the steps of sending a system management interrupt signal to a processor of the computer, wherein the processor enters a system management mode after receiving the system management interrupt signal, and the system management model is independent of an operating system of the computer; carrying out a preset detection command under the system management model through the processor so as to generate a corresponding detection signal, and judging the reasons why there is breakdown in the computer according to the detection signal. For the computer which has a dead-halt break down, judgment whether the break down belongs to the dead-halt caused by software or belongs to the dead-halt caused by hardware can be accurately made through the method and device, and thus the method and device makes it convenient for a user to quickly and accurately find and solve the dead halt breakdown of the computer.

Description

technical field [0001] The invention relates to the field of computer detection, in particular to a computer fault detection method and device. Background technique [0002] During the research and development of computers (including desktop computers and notebook computers) or consumer use stages, system crashes often occur. At this time, it is often impossible to accurately determine whether the specific situation is due to hardware crashes or software crashes, so that it is difficult to solve the crash problem. There is a deviation in the general direction, and the fault cannot be located and resolved quickly. Because when the computer system crashes, the appearance is the same, for example, the mouse cannot be moved, the caps lock light does not respond, the screen does not update, etc. Therefore, the above-mentioned problems cause troubles for R&D personnel and consumers to accurately judge and eliminate faults in a short period of time. [0003] Generally speaking, t...
