Welcome to HP Forums,

This is a great place to get support, find answers and tips,

Thank you for posting your query, I'll be more than glad to help you out 🙂

I understand the touchscreen isn't working, Don't worry I'll do my best to help you with this.

To provide you with an accurate solution, I'll need a few more details:

Did this happen after a recent software update?

Have you tried checking the display on an external monitor?

In the meantime, let's try these steps here: Many startup errors and other problems can be resolved by decreasing the amount of power stored in hardware components. Decreasing stored power is sometimes referred to as a "Hard Reset". Use the following steps to perform a hard reset on a computer:

Many startup errors and other problems can be resolved by decreasing the amount of power stored in hardware components. Decreasing stored power is sometimes referred to as a "Hard Reset". Use the following steps to perform a hard reset on a computer:

1. If Windows is open, click Start and then Shutdown.

   If Windows is not open and the computer has power, press and hold the power button on the computer until the computer shuts off.

2. With the power off, disconnect the power cord from the back of the computer.

3. With the power off and the power cord disconnected, press the power button on the computer for 5 seconds. The power light indicator on or near the power button might turn on briefly but then go out.

4. Reconnect the power cord and turn on the power.

I would recommend you to check if the Touchscreen is responding on the BIOS by restarting the computer and tapping on the F10 key.

Perform a touch screen diagnostic test in HP Hardware Diagnostics

Use the HP PC Hardware Diagnostics UEFI tests to detect problems with the touchscreen 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 touchscreen 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.

    

• If the diagnostics tests pass but the touch screen still does not respond during regular use, continue to the next step.

• If one or both tests fail, a 24-digit code, or failure ID, displays. Contact HP and provide this code. The failure ID is also available in Test Logs on the main menu.
