The invention provides a startup / shutdown and reset test card for a computer motherboard. The startup / shutdown and reset test card for the computer motherboard comprises a test card body, wherein a Complex Programmable Logic Device (CPLD) chip, a Light Emitting Diode (LED) indicator lamp, an RS232 serial port, a reset circuit interface and a power interface are arranged on the test card body; the CPLD chip is connected with the RS232 serial port, the LED indicator lamp, the reset circuit interface and the power interface; the CPLD chip is connected with the motherboard through the RS232 serial port; the CPLD chip is connected with an ATX power supply, connected with the motherboard, through the power interface; the CPLD chip passes through the reset circuit interface. Compared with the prior art, the startup / shutdown and reset test card for the computer motherboard has the advantages that automatic testing is realized, and the manpower cost is reduced; long-time continuous testing can be performed, the test efficiency is improved, and the test time is shortened; the wrong time frequency can be automatically recorded, a test report is generated, and errors caused by human factors are reduced.
Description
technical field [0001] The invention belongs to the technical field of computer mainboard testing, and in particular relates to a computer mainboard switch and reset test card. Background technique [0002] For a well-designed computer motherboard, a long-term power-on and reset test must be carried out to verify the stability of the power-on and reset of the motherboard, whether there is any failure to start the computer normally, and whether the reset circuit can reliably reset the computer every time; Generally, tens of thousands of tests are required to calculate the failure rate. For some demanding applications, the failure rate is required to be 0. The traditional motherboard power-on and power-off tests are performed by connecting the motherboard to the ATX power supply (or AT power supply) and manually powering on and off to realize the power-on and power-off test. It is also difficult for testers to record accurately. Contents of the invention [0003] In view o...
