Hi @khobbyCollins,
 
Welcome to the HP Support Community!

Thanks for reaching out!

I understand how  it must feel when your touchscreen suddenly stops working, especially since it was fine at first. Thank you for sharing the details about the error message and the yellow triangle in Device Manager that’s very helpful.
 

Could you please confirm if there were any recent updates or changes (like Windows updates or driver installations) before the issue started.

Here are a few  steps you can try in the meantime:

• Restart your laptop: A simple reboot can sometimes clear temporary driver conflicts.
• Update drivers: In Device Manager, right-click the touchscreen driver (usually listed under Human Interface Devices) and select Update driver. Choose Search automatically for updated driver software.
• Uninstall and reinstall driver: Right-click the driver with the yellow triangle, select Uninstall device, then restart your laptop. Windows should reinstall the driver automatically.
• Run Windows Update: Make sure your system is fully updated, as updates often include fixes for hardware compatibility.
• Check HP Support Assistant: If installed, run HP Support Assistant to detect and fix driver issues specific to your model.

If none of these steps resolve the issue, we may need to look into whether the touchscreen hardware itself is affected.
 

I hope this helps.
