Problems solved by technology

[0002] Testing whether the power good signal output of motherboard components such as the central processing unit is normal is one of the test items of the motherboard system test. At present, each power supply pin of the motherboard component to be tested is often tested one by one with a multimeter and other test instruments, which takes a long time and requires a lot of work. In addition, the integration level of the motherboard circuit is getting higher and higher, which may easily lead to the consequences of mismeasurement due to misidentification of component power pins

Embodiment Construction

[0022] Please refer to figure 1 and figure 2 , the preferred embodiment of the computer 100 of the present invention includes a motherboard 40 and a test card 50 .

[0023] The motherboard 40 includes a CPU 90 , an internal memory 80 and an interface 70 .

[0024] The central processing unit 90 is used to output four groups of power good signals, the first group is VCC_CPU0_PWRGD signal and VCC_CPU1_PWRGD signal, the second group is VSA_CPU0_PWRGD signal and VSA_CPU1_PWRGD signal, the third group is PLL_CPU0_PWRGD signal and PLL_CPU1_PWRGD signal, and the fourth group is VTT_CPU0_PWRGD signal and the VTT_CPU1_PWRGD signal, each power good signal to be tested corresponds to a power output terminal of the CPU 90 .

[0025] In this embodiment, the internal memory 80 is a DDR3 (Double Data Rate 3) internal memory, and the internal memory 80 is used to output two sets of power good signals, the first set is DDR3_VDDQ_CPU0_PWRGD signal and DDR3_VDDQ_CPU1_PWRGD signal, and the sec...

Abstract

The invention discloses a computer. The computer comprises a main board and a test card, wherein the main board comprises a CPU (Central Processing Unit), an internal storage and an interface, and the interface comprises signal pins of which the number is the same as that of to-be-tested power good signals of the CPU and the internal storage; and the test card comprises a connector and indicating circuits of which the number is the same as that of the signal pins of the interface, the connector comprises signal pins of which the number is the same as that of the signal pins of the interface, and each indicating circuit is correspondingly connected with one signal pin of the connector for indicating whether a high-level signal is input by each signal pin or not. According to the computer disclosed by the invention, a test result of multiple to-be-tested power good signals can be obtained in one step, and the test is fast and time-saving. The invention also relates to the main board and the test card.

Description

technical field [0001] The invention relates to a computer, its main board and a test card. Background technique [0002] Testing whether the power good signal output of motherboard components such as the central processing unit is normal is one of the test items of the motherboard system test. At present, each power supply pin of the motherboard component to be tested is often tested one by one with a multimeter and other test instruments, which takes a long time and requires a lot of work. In addition, the integration level of the motherboard circuit is getting higher and higher, which may easily lead to mismeasurement due to misidentification of component power pins. Contents of the invention [0003] In view of the above, it is necessary to provide a computer, its mainboard and a test card that can automatically indicate whether the power good signal of the mainboard components is output normally. [0004] A computer comprising: [0005] A motherboard, including: ...
