Touch screen not working

[CPace2020]

My touch screen is no longer working.  The computer does have a touch screen and it worked.  Based on all the trouble shooting articles and steps from the device manager - human interface menu to the pen and touch section it would seem as if my computer does not have a touch screen but it does and it has worked in the past. I have no idea what to do now.  Please help.

Thank you for posting on the HP Support Community.

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:

• Did this happen after a recent window or software update?
• Have you made any hardware/software changes?
• Did you make any changes on the settings of your PC prior to the issue?
• When was the last time it worked fine?

Use the HP PC Hardware Diagnostics UEFI tests to detect problems with the touch screen hardware.

1. Connect the AC adapter to the computer.

2. Press the Power button for at least five seconds to turn off the computer.

3. Turn on the computer and immediately press Esc repeatedly, about once every second. When the Startup menu appears, press F2.

4. When the HP PC Hardware Diagnostics screen displays, click Component Tests.

   

5. Click Touch Screen.

6. There are two interactive touch screen hardware tests. Click Touch Pointer Test first.

   

7. Read the on-screen instructions, and then click Run once.

8. Touch each of the blocks on the screen to erase them. The test ends after you erase all the blocks or after three minutes have passed, and the results display.

   

9. Click Main menu to return to the main screen.

10. Click Component Tests, and then click Touch Screen.

11. Click Drag And Drop Test.

    

12. Read the on-screen instructions, and then click Run once.

13. Drag each orange rectangle to the box indicated by the arrows with a finger or a stylus. The test ends after you reposition all the blocks or after three minutes, and the results display.

    

Hope this helps! Keep me posted for further assistance.
