Embodiment Construction

[0026] see figure 1 , the present invention is a method for detecting and diagnosing hardware faults when the computer is turned on without display. The method is to insert the computer from the power plug into the power socket, prepare to power on, and divide the entire power-on process of the computer until the BIOS self-checks to the display card. For four stages, the key timing, signal or execution action of the relevant hardware in the four stages, or detect the diagnostic information of the BIOS during the self-testing process, and use the alarm device (such as a light-emitting diode) to indicate the detection result, and then according to these The state of the warning device determines the main board, or memory, or power supply, or CPU that has failed, so as to realize hardware fault diagnosis.

[0027] The method of the present invention can be divided into four operating steps according to the four stages of the power-on process:

[0028] The first stage is the pre-...

Abstract

A method for detecting and diagnosing hardware faults when the computer is turned on without a display is to insert the power plug of the computer into the power socket and prepare for power-on until the BIOS self-checks the display card. The whole power-on process of the computer is divided into several stages. Detect the timing, signals or execution actions of related hardware in each stage, or detect the diagnostic information of the BIOS during the self-testing process, and output the detection results of each stage to the alarm device, according to the state of the alarm device (such as a light emitting diode) To locate the faulty components and implement hardware fault diagnosis. The device is composed of a plurality of detection circuits arranged centrally on a plug-in card or directly on the main board and light-emitting diodes on the front panel. The present invention solves the problem that technical personnel must carry a full set of spare replacement parts to door-to-door service in order to determine the cause of the fault and the high cost of troubleshooting, improve the accuracy and efficiency of maintenance, and enhance the brand image of the manufacturer.

Description

technical field [0001] The invention relates to a method for detecting and diagnosing computer hardware faults, specifically, a method for detecting and diagnosing hardware faults that are not displayed when the computer is turned on, and belongs to the technical field of computer detection. Background technique [0002] In the after-sales service of computers, no display after booting is a hot spot that users often complain about. The so-called power-on without display means that there is a failure in the relevant links in the time period from the time when the power button on the front panel is pressed until the basic input and output system (BIOS) self-tests to the display card, which causes the power-on process of the system to be interrupted, so the system does not display . The components involved in this stage include power supply, motherboard, memory, CPU, BIOS and other hardware and software. [0003] At present, the after-sales service technicians mainly adopt th...
