Have you ever encountered such a problem: in order to make your mini PC more power-efficient, when it goes to sleep or is shut down, you find that:
It cannot be awakened by mouse or keyboard. You must press the power button on the body.
If you want to charge devices such as headphones and mobile phones through the USB port of a mini PC, you must keep the computer on throughout the process.

Ii. Operating Guide
2.1 When disassembling the GT model in a power-off state, 10 screws (9 M3 and 1 M2) need to be removed to open the case.
There are three on the left side of the case
Three on the right side
Four on the rear side
2.2 Use tweezers, insert them into the anti-theft lock hole, and pull out the rear side baffle.
2.3 Pull out the upper shell towards the rear baffle.
Three, find the "USB_POWER" pin header on the motherboard
This set of pins has three pins. We number them as [1] [2] [3]
Default position (1-2 short-circuited) : The jumper cap is connected to pins [1] and [2]. At this point, when the USB3.0 port is turned off or in sleep mode, the power will be cut off.
The operation process for continuous power supply to the USB3.0 port in the off/sleep state:
Use tweezers to gently pull out the jumper cap at the default position vertically upwards.
Then accurately place it on the other two target pins ([2] and [3]).
After confirming that the jumper cap is in good contact with the pins, it can be installed in the chassis (you can do not tighten the screws first and fix it after the test is successful).
