Description

Technical Field

[0001] The present invention relates to the technical field of computer fault diagnosis and alarm, in particular to a computer mainboard hardware fault diagnosis and alarm device. Background Art

[0002] When diagnosing a computer motherboard hardware fault, you first need to insert the diagnostic card into the computer's PCI slot or ISA slot, turn on the computer's power, and observe whether the multiple LED indications of the test card are normal. When there is a fault in the computer motherboard hardware, the corresponding LED lights up to issue a warning, and the buzzer emits a corresponding sound. The computer motherboard hardware fault can be diagnosed based on the display results of the LED, buzzer or diagnostic card code.

[0003] For example, CN1713156A discloses a method for detecting and diagnosing hardware failures of a computer that has no display when it is turned on. The method comprises the following steps: inserting the power plug of the computer into a power socket and preparing to power on the computer until the BIOS self-checks the display card. The entire power-on process of the computer is divided into several stages. A circuit is used to detect the timing, signal or execution action of the relevant hardware in each stage, or to detect the diagnostic information of the BIOS during the self-check process. The detection results of each stage are output to an alarm device, and the faulty components are located according to the status of the alarm device (such as a light-emitting diode) to realize hardware fault diagnosis. The device is composed of a plurality of detection circuits and light-emitting diodes on the front panel, which are centrally arranged on a plug-in card or directly arranged on the mainboard. The present invention solves the current problem that a technician must bring a full set of spare replacement parts for on-site service to determine the cause of the fault and the high cost of troubleshooting, thereby improving the accuracy and efficiency of maintenance and enhancing the brand image of the manufacturer.

[0004] However, the gold finger coating of the diagnostic card is easily worn out after frequent plugging and unplugging, exposing the underlying metal. The exposed metal is easily oxidized to form an oxide layer after contact with air, resulting in unstable signal transmission and affecting the normal operation of the diagnostic card.
