[0054] In the embodiment of the present disclosure, the first output terminal and the second output terminal can be connected to the power unit of the external device through a switching circuit to provide corresponding voltages.

In a specific implementation, the conduction control of the first switch circuit 5 is realized by using a keyboard 18 hotkey. The test verification can be enabled or disabled by a predefined hotkey value. By controlling the first switch circuit 5 by the keyboard 18 hotkey, multi-channel output of the electronic device under test can be realized, and the structure is simple and easy to implement.

[0058] The user operates the shortcut key to store the key value in the memory of the embedded controller 4. During the test and verification, the key value stored in the embedded controller 4 is parsed to obtain the predefined control instruction, thereby controlling the first input terminal corresponding to the first switch circuit 5 to be turned on.

[0059] According to the input key value, the user controls the corresponding mode circuit to be turned on through the analog-to-digital selection unit to achieve corresponding test verification.

[0060] Table 1 below is an example of the definition of shortcut key values.

[0061] Table 1

[0062] Function shortcut key use Turn off debugging Fn+D+0 (press to take effect in S5) Turn off debugging CPU serial port function Fn+D+1 (press to take effect under S5) Connect the CPU serial port EC serial port function Fn+D+8 (press to take effect under S5) Connect EC serial port EC upgrade and commissioning Fn+D+9 (press to take effect in S5) Turn on the EC SMBUS bus

When the USB mode circuit 8 is selected to be turned on, the system operation log can be transmitted to the terminal in real time via USB for storage and real-time display. When the storage mode circuit 9 is selected to be turned on, the system operation log can be stored in real time in the SDIO card or SD card, and the system operation log in the SDIO card or SD card can be read through the reading interface. When the network mode circuit 11 is selected to be turned on, the system operation log can be transmitted to a remote server via the network.

[0064] When the first switch circuit 5 conducts the EC serial port input terminal, the user can conduct the digital display circuit 12 through the mode selection unit 16 to display the power-on self-test code in real time. Different power-on self-test codes can be displayed according to the specific shortcut key value of the EC serial port input terminal.

[0065] When the first switch circuit 5 turns on the EC bus input terminal, the user can turn on the reserved debugging interface circuit 13 through the mode selection unit 16 to update and / or debug the program of the embedded controller 4 .

[0066] When there is no control instruction generated based on the shortcut key in the embedded controller 4 , the first switch circuit 5 turns on the USB input terminal of the mainboard by default, which will not affect the input and output functions of the mainboard 1 .
