Touchscreen driver missing, device manager not detecting - windows update or new hard drive issue?

HP Elitebook 850 G3
Microsoft Windows 10 (64-bit)

Hi,

I own an Elitebook 850 G3 with 64 bit windows and touch screen. I recently purchased and refurbished with new SSD drive and upgraded the RAM. The touch screen was working about a week ago and I recently noticed that the touch screen no longer works and the device manager does not show "hid-compliant touch screen" device. Furthermore, scanning for recent hardware changes has no effect and my "touch and pen settings" show no device available. 

 

I've been trying to see if there is a driver fix or if this is because of the Windows 10 update that installed itself about 3 days ago. To make it more interesting, I upgraded the hard drive last week, so either one could be the cause. Any thoughts? Help! Thanks in advance

Touchscreen driver missing, device manager not detecting - windows update or new hard drive issue?

@iarebass

 

Hello;

Allow me to welcome you to the HP forums!

 

Isn't Win10 just wonderful -- it works fine for months and then suddenly, without warning, it stops working!

 

First thing I would suggest is dealing with the possible Win10 driver update.  


You need to go into Settings, Update & Security --> Windows Update.

Then, choose Advanced Options --> History to see when updates were last applied. If you see any that include device drivers, those could be the problem. So, if you can, you should see if you can rollback the drivers that are causing the problem. You do this by going into Device Manager, seeing if the appropriate device is still listed, and if so, trying to rollback the last driver update.

And if that fixes the problem, then consider disabling future driver updates using the information in the link: http://www.tenforums.com/tutorials/48277-driver-updates-windows-update-enable-disable-windows-10-a.h...

Note: I have disabled driver updates on ALL my Win10 PC, and life under Win10 has been a lot more pleasant every since!

 

Then you mentioned that the device is no longer listed.  what MIGHT work is something known as a Repair-Install. This is the least destructive of all the Windows recovery functions and rewrites the Windows system files, leaving your data, settings, and applications intact.

To do this, you will need to use the link to download Win10 installation media and either burn a DVD or create a USB stick: http://windows.microsoft.com/en-us/windows-10/media-creation-tool-install?ocid=ms_wol_win10

Once you have that, follow the instructions in the link: http://www.tenforums.com/tutorials/16397-repair-install-windows-10-place-upgrade.html

Good Luck

I did more research and found that the "I2C HID Device" is failing to start and this controls the touch screen. I searched HP, under my laptop model/serial, for links to the driver and only found a driver for Atmel I2C-HID maXTouch Driver and for Intel HID-I2C Controller Drivers, both of which are only supported on Windows 7.

 

Is there a Windows 10 compatible version of Intel HID-I2C controller driver that enables touch screen?
