Here is the data you requested:

Serial # 8CC6210LMH
Prod # V8K13AA#ABL

Model # 24-b029c

There are so many Windows update. (Windows 10 pro) that I'm assuming this happened after an update. When I can't recall since I just occasionnaly used the Tablet mode. But now I really needed it and the screen does not react to Touch anymore.
The device manager doesn't even show the Touch option in the Human Interface drivers.

I've just had it happen with a desktop right out of the box. I've seen similiar posts elsewhere about the same issue. My computer is treating the touchscreen as if it's non existant

Update: Just swapped it with a new one, which has a functioning touchscreen.
