Power state test system

The invention relates to an automatic testing technology, in particular to an automatic testing system of a computer device, which can actually provide an output signal of a button of a wake-up device, so that the test result has better credibility.

Advanced Configuration and Power Interface (ACPI) is a common management specification for the power management interface of a set of operating systems. It has developed various levels of computer systems (such as desktop computers or workstations). The mode of operation of the hardware in different power states. Among them, under the ACPI specification, the power state includes at least the following states:

S0: Normally powered on, all major hardware of the computer system including the central processing unit (CPU), memory and hard disk can work normally.

S3: Also known as sleep state, this state will stop supplying power to the CPU and hard disk. At this time, the computer system will still supply power to the memory, and the state of the computer system will be temporarily stored in the memory before entering the sleep state. .

S4: Also known as the sleep state, this state will stop supplying power to the main hardware of the computer system, but the computer system is stored in the hard disk before entering the sleep state, and the computer system is woken up longer than the S3.

S5: Shutdown status.

Traditionally, when testing a computer system to comply with ACPI specifications, most of them rely on testers to manually set the power state of the computer system, such as manually triggering the power switch or keyboard, mouse, etc. to wake up the computer system. From S3, S4, and S5, for example, it returns to the S0 state, and the tester judges whether the wakeup action of the computer system is normal. As a result, the traditional test method not only consumes a lot of testers' time, but also the tester may have the error of artificially determining the error and cannot improve the test quality and accuracy.

In the prior art, in order to solve the above problems, some people have directly set the different power states of the computer system under test through software control, and record the test results. Although the labor trouble of the tester is omitted, the test using the software to provide the virtual test signal is not tested by the hardware circuit, and it is impossible to simulate whether the hardware works normally, obvious and actual manual operation. Different tests make the test results have limited credibility.

In view of this, one of the objects of the present invention is to provide a power state test system that can perform tests automatically, eliminating the trouble of manual operations.

Another object of the present invention is to provide a power state test system that uses real hardware to provide test signals for waking up a computer system, thereby improving the credibility of test results.

In order to achieve the above object, the present invention provides a power state test system for testing different power states of a computer to be tested, including a test computer, a control device, a wake-up device, and a network connection device. The test computer is connected to the network connection device and can output a trigger signal, and the computer to be tested is connected to the network connection device. The control device is electrically connected to the test computer and has an electronic switch operable according to the trigger signal. Wake up The device is electrically connected to at least one peripheral input unit of the computer to be tested, and the peripheral input unit is electrically connected to the control device, so that the peripheral input unit can be controlled by the control device to generate a test signal to wake up the computer to be tested.

Thereby, the present invention actually outputs power to the wake-up device through the control device, so that one of the peripheral input units of the wake-up device can generate an actual test signal to wake up the computer to be tested, and the effect is equivalent to manually pressing the button of the peripheral input unit. To wake up the computer to be tested, so that the test results are more credible. In another aspect, the present invention automatically controls the control device to output a driving signal through a computer, so that the peripheral input unit of the wake-up device can wake up the computer to be tested for testing, and can replace the traditional manual operation and shorten the judgment. Time and eliminate the possibility of human error. At the same time, the computer can monitor the status of the computer to be tested through the network connection device.
