Touchscreen stopped working

[Ferretness]

My laptop DOES have a touchscreen. It's been working just fine. Suddenly, tonight, it's not working. I went through all the steps in the virtual assistant. Windows doesn't even think I have a touchscreen, now. I'm not happy, to say the least.

As I understand, the touchscreen does not work, 

No worries, as I'll be glad to help you, that said, I'll need a few more details to dissect your concern & provide an accurate solution:

When was the last time it worked without these issues?

Did you run a hardware test for Touchscreen on the computer using the F2 key during a restart?

The link you put to find the product number didn't work, but I figured out how to find it.

Product number: N3Y44UAR#ABA

Last time I remember the touchscreen working was within the past month, but I don't remember specifically when.

Yes, a hardware test during startup from using the F2 key was part of the automated assistant.

I think I said before that I followed EVERY STEP the automated assistant had. Yes, this notebook has a touchscreen. Yes, it worked int he past. Now, it doesn't work. It doesn't even exist in the Device Manager anymore. The hardware test during startup didn't work.
