HP Pavilion x360 - 15t-dq100 CTO
Microsoft Windows 11

My touchpad has randomly stopped working.  I say randomly because it was working fine this past Sunday, I went to a pool party, and then came home and it was no longer working, and no updates appeared to have occurred during the time. 

From what I can see:

My touchpad is no longer in my devises. 

Under Device Manager my ELAN Input device under "Mice and other pointing devices" ( Think this is the driver for the touchpad) is either not shown at all or says it can't connect (Code 45). It various on which.

My I2C HID Device Driver says it cannot start (Code 10)

I have tried everything I can think of and that the internet recommends, including:

Restarting

Deactivating the Drives and reactivating. 

Uninstalling the drivers and reinstalling

Updating the drivers

Rolling back that drivers (where able)

Installing new/different drivers

Restoring my BIOS when booting up computer (my touchpad works fine in the BIOS screen, as well as the test hardware screen... all prior to windows loading...)

Recovering windows (windows 10) from the day before the issue occurred.

Recovering windows from several weeks before the issue occurred.

Downloading and installing Windows 11, which I didnt want to do...

The only thing I haven't tried yet, is doing a hard system reset, which I also dont want to do...

Is there anything else I can try? Or should try again in case I did it wrong?

Hi @JB785,

 

Welcome to the HP Support Community

I'd like to help!

 

I understand that you are facing issues with the Touchpad on your HP Pavilion X360 - 15t-Dq100 CTO PC. 

 

I see that you have already tried troubleshooting on your own and covered pretty much everything. 

However please run a hardware test from the UEFI window (Unified Extensible Firmware Interface) to check the hardware functionality of the touchpad.


Kindly click on the link to view the video that shows how to run a UEFI Test on your notebook PC. If the hardware test pass, then the touchpad hardware is fine. 

 

While you respond to that, also try to perform a hard reset on the unit. We understand you would not like to do that. But it is a part of troubleshooting.

 

  • Disconnect the unit from the AC Adapter and any other external peripherals connected to the unit.
  • Press and hold down both the power button and mute button together for around 10-15 seconds.
  • Connect the AC Adapter back and switch on the unit

Hope this helps! Keep me posted.

I completed the hardware test from the UEFI window and no issues were detected. The test passed. While in this window, the touchpad works fine. Further, I also tested the mouse/touchpad in the UEFI window, doing both the "pointer test" and "drag and drop test" and was able to perform both with the touchpad with no issues. However upon actually booting up windows, the touch pad no longer functions again. 

 

I also did the hard reset as you recommend with no change.

 

Thanks!
