Have you modified anything in the Bios? You will not have disabled the USB ports on the Bios? ---

By disabling the USB port you will not be able to use any keyboard device to access the Bios. The only valid solution is to reprogram the bios with an external programmer. Anyway, try this in case it works: 1. Press the power button for 30 seconds 2. Press the power button three times in short half-second presses 3. Put the charger and press the power button until it turns on and check if the bios has been reset ---

Everything is because the KMDF HID Minidriver for Touch I2C driver does not work properly in win10 :困:困:困: ---

There was no otg before, so entering the BIOS is the reply option of Win10 → Troubleshooting → UEFI enters the BIOS Later I found out that I set the wrong otg device 1.2.3 ![image](https://us1.discourse-cdn.com/flex020/uploads/chuwi/original/2X/a/a5b5a51c6c4e7207c08ebc466d74b2e8ec0189c7.jpeg) Now, there shouldn’t be too much problem entering the BIOS
