Test fixture and computer device detection method

The invention relates to a fixture; in particular to a detection fixture and a detection method suitable for a computer device.

In the currently widely used operating systems, the power management functions of the Advanced Configuration and Power Interface (ACPI) have been integrated in their operating systems to control the related hardware in the computer system. Power management operations. In the Advanced Configuration and Power Interface (ACPI) standard, the state of the computer system includes a sleep mode that consumes less power than the operating state S0. According to the power consumption and the recovery speed, the sleep state can be divided into several levels such as S1, S2, S3, S4 and S5.

In the S1 (power on suspend) state, the computer system only shuts down the screen, stops supplying power to the monitor and the disk drive, but still supplies power to the CPU, memory and fan, so it can quickly return to work. . In the S2 state, in addition to stopping the supply of power to the monitor and the disk drive, the power supply to the central processing unit and the cache memory is also stopped. In the S3 state called suspend to ram, except for the memory and its controller that require power to hold the data, the rest of the devices stop supplying power. The S4 (suspend to disk) state stores the data in the memory on the hard disk, so there is no need to supply power to all devices and components, but the operating system can store the original open data and program execution status before the power is turned off. . To wake up the sleepy computer system back to the normal power-on state, simply press the power switch to quickly restore the original state without re-executing the lengthy system startup procedure. The so-called S5 state is the shutdown state, at which time only very little standby power is reserved to the computer system.

In order to ensure that the computer device can perform various functions normally when the user uses it, the computer product must undergo multiple quality control tests before shipment, and in the quality control test, the sleep wake-up test is one of the essential items. The most commonly used test method at present is repeated execution. Programs for boot, standby, hibernation, Shutdown, and Reboot.

When the sleep power-on test is performed by manually pressing the computer power button, the tester must repeatedly press the power button, so the tester needs to wait for a long time before the test machine to perform repeated operations, and needs to record the data that has been tested. This kind of repetitive work tends to make the tester feel tired. In addition, the above-mentioned sleep mode test method is not only time-consuming and extremely labor-intensive, but also very easy to cause personnel misoperation, the test misjudgment rate is also high, and the manual method is obviously not efficient. In addition, because the tester judges the naked eye during the test, and the defective product is not detected due to misjudgment, there is a possibility that the normal product is judged to be a defective product.

In order to overcome the technical problems on the aforementioned conventional test computer devices, the industry has developed a technology for automatically testing the sleep mode. However, the conventional automatic test device must be limited to the test of the circuit system of the computer device to be tested using a specific software program. Therefore, in addition to the relatively high cost of the test, the selection of the hardware test device is relatively limited, resulting in the test. The use of workstations also lacks flexibility and adaptability.

In view of the above problems, the present invention provides a detection method for detecting a jig and a computer device, thereby solving the prior art that the computer device is easily tested by a manual test, and the detection of the computer device by the software program is expensive and the use is lacking. Resilience and adaptability.

The test fixture of the present invention is applicable to a computer device. The test fixture includes a circuit board, at least one display interface, and a control interface. The circuit board has a control chip, and the control chip stores test parameters. The display interface is electrically disposed on the circuit board and electrically connected to the computer device, and the display interface receives the sleep signal output by the computer device in the sleep state. The control interface is electrically disposed on the circuit board, and the control interface is electrically connected to an electromagnet device. The electromagnet device is adjacent to the computer device. When the control interface outputs a test signal to the electromagnet device, the electromagnet device is activated and triggers the computer device to enter a sleep state. The control chip determines whether it is received according to the set test parameters. The sleep signal, if the control chip receives the sleep signal, confirms that the computer device enters a sleep state.

The invention further discloses a detection method of a computer device. Firstly, a detection fixture is provided, and test parameters of the detection fixture are set, and then the detection fixture and the computer device are electrically connected. Pressing the test button of the test fixture causes the control interface of the test fixture to output a test signal to activate the electromagnet device to trigger the computer device to enter a sleep state. The detection fixture determines whether the sleep signal output by the computer device in the sleep state is received. If the detection fixture receives the sleep signal, it confirms that the computer device enters the sleep state.

With the test fixture and the test method of the invention, the automatic test computer device can be realized by the hardware device, the test accuracy and the test coverage rate are greatly improved, and the labor cost of the detection and the software program development cost are reduced. In addition, the test fixture of the present invention can be applied to computer devices of various specifications for testing, and can test multiple computer devices at the same time, thereby effectively improving the detection efficiency.
