Display sensor not work

[Dm771]

Hello.

Display sensor does not work. A required device is missing from Device Manager ( Human Interface Devices)

I can reboot the laptop and in some unknown way the sensor can start working again.
However, then the next day or a few days later I turn on the laptop and the sensor does not work. Like at this time.

Thanks for answer .

I installed a different version of the driver and do not see any problems with the operation of the touchscreen. If it starts to fail again, I’ll try to follow the recommendations for resetting with buttons.

Alas. After the reboot, the screen stopped working on touch again, and there was an error in the device manager. I followed the second recommended step and after some time after holding down three buttons, the BIOS entered recovery mode.

Then there was a BIOS error 500 on a black background, but the computer still booted normally.

The problem is with the Intel display driver.
I installed the 2018 version  ( only driver Intel) and there are no more problems with the sensor.
I decided not to touch the BIOS and no longer experiment with the buttons based on your recommendation.
