HP 4t-1100 touchscreen non-functional under Windows 10

[jefmac]

Hi -

Note: I found an orphaned post from 2015 about what sounds like my issue (link: https://h30434.www3.hp.com/t5/Notebooks-Archive-Read-Only/Hp-Envy-Touchsmart-Touchscreen-not-working...), but it's not been resolved and listed as archived, so I'm checking to see what progress HP might have made in the last 5 years to assist debugging and ultimately restoring the full functionality of this device. 🙂

HP Envy 4t-1100
Product: C4H46AV

Touch Screen worked under 8.1, does not work under Windows 10. Otherwise, the device is completely functional, with no Bang'd out devices in the Device Manager.

There is no HID-Compliant Touch Screen entry in the Device Manager.

I downloaded both the Start-up version and the Windows version of the HP PC Hardware Diagnostics application and neither version lists the touchscreen in the Component Tests.

Any thoughts on how to move forward? I seem to be seeing a lot of posts about similar things happening with HP touch devices, but I have not yet been able to find a solid solution.

Thanks for any help you can offer!

Thank you for posting on the HP Support Community.

Don't worry as I'll be glad to help,  I have a few troubleshooting steps we could try to fix the issue:  

Let's perform a touch screen diagnostic test in HP Hardware Diagnostics
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 the 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.

Hope this helps! Keep me posted for further assistance.

Hi Echo_Lake,

Thanks so much for this detailed response. I will be running through this when I get to the machine and should be able to reply this weekend.

Really appreciate the help!

Hey Echo_Lake,

Finally am at the machine now. Followed your instructions and have got hung up on not having a touch screen test section.

The version of the HP PC Hardware Diagnostics UEFI is Version 6.5.0.0, so I'm not sure whether there is some different version which contains the touch screen tests (I may have force-updated the Diagnostics last time I was thrashing away trying to figure this out)?

I've walked through all of the menu items under Component Tests and none of them relate to the touch screen.

Suggestions for my next steps?

Here's the Component Tests screen so you can see what I'm looking at.

Thank you for posting back. 

The last thing I can suggest trying to restore the computer back to the factory settings. Performing an HP system recovery (Windows ) While doing the recovery there is an option to backup your personal files. If you have not previously done one now is a good time. 

Restoring Files that were Backed Up Using HP Recovery Manager (Windows )You can also contact HP support for assistance. They can remotely access your system to help alleviate difficulties: www.hp.com/contacthp/

The HP Cloud Recovery Tool allows you to download recovery software to a USB drive. You can use the downloaded recovery image file in order to install the Windows operating system.
