My touchscreen driver has disappeared!

I was using my Spin 3 (Acer SP315-51-37E7) in tablet mode a few days ago when all of a sudden, the touchscreen stopped working. I checked Device Manager and didn't see it. I enabled "show hidden" and I saw it then. I right-clicked to see if I could update/reinstall/repair the driver, however, those options were not available.

So I did a restart and checked again... it was gone, not hidden, gone.
So I did a reset hoping that would work. Nope.
I did a clean installation of Windows 10, that didn't work either.
Windows 10 has been completely updated, I've restarted, and it's still not there.
I've checked the downloads available for my model (SP315-51-37E7) on Acer's website and no touchscreen driver is listed. (https://www.acer.com/ac/en/US/content/support-product/6960?b=1)
I checked with Microsoft and they don't have it either.
I tried "Driver Easy" to see if it could locate and download the driver, but it didn't have it either.

I've also just noticed that there is no longer an option to go into tablet mode, which is why I chose this model.

Does anyone know where I can find and download the HID-Compliant Touch Screen driver so I can enable the touchscreen?

Welcome!

i assume this laptop is about 5+ years old? And supposedly this machine is registered to some company.

the reasonI ask about the age is that Itoo don’t see much drivers.

Do you see any device for the HId? If so, please find the VEN and DEV numbers in the Hardware tab.
If you can’t, then I suspect that the touch component is now defective.

Hello, no, the laptop is almost 3 years old... I purchased it June 6, 2018 and started using it a couple weeks later.

It's an Acer so I imagine it's registered with them. I did have a warranty however it expired after a year.

What device specifically do you mean? There are a quite a lot of HID drivers... Here's a screen cap of my device manager showing all the HID drivers, including hidden "ghost" drivers.

As you can see, the HID-compliant touch screen driver is no longer there.

Did this happen after an update? If so can you remember which update?
Have you downloaded the Acer software to automatically check for drivers?
Is the BIOS up to date?
Is there any Tablet mode icon under Action centre?

If you boot to the BIOS can you use the touchscreen there?
If not then the hardware may have failed.
Run the Hardware & devices troubleshooter: Type Troubleshoot under search & choose Hardware & devices & then click troubleshoot.
Right click Start>Powershell with admin & enter: set devmgr_show_nonpresent_devices=1
Then go to device management, scan for hardware changes & see if the Touchscreen is listed, if so you can either try updating/installing the drivers or uninstall it then scan for hardware changes.
If you uninstall the touchscreen driver then restart the PC & go back to device manager & scan for hardware changes again to reinstall the driver.

Is the KB4480116 update installed as this can affect touchscreen devices? If yes then try uninstalling it.

More suggestions:
Search the device for Calibrate the screen for pen and touch input, once on the settings choose setup & then touch input & retest the touchscreen.
If that doesn’t work then Click Start>Run & enter regedit, find HKEY_CURRENT_USER\Software\Microsoft\Wisp\Touch & change the Touchgate value to 1 then restart the PC & test the touchscreen.

Also check under Mice & Other pointing devices for a USB touchscreen controller.
If it’s listed then try updating the driver or reinstalling the current one.

UPDATE: The touchscreen and tablet mode are back!! :giggle: (but now I'm having HDMI external display issues. :confused:)

After doing another reset and buying and trying Driver Easy to see if it would fix the driver, I was ready to give up and just use this laptop with reduced capabilities until I could buy a new one, however, my laptop developed HDMI external display issues and in my search to repair that, I actually fixed the touchscreen and tablet mode issue.

I was messing around with display settings to get the external display to work...the laptop starts to send the display over to the external monitor, but then goes white. When nothing seemed to work, I went into Device Manager and noticed that there was an "unknown device" listed. I did not see this before... I don't know if I just missed it, or if popped back up after another reset and using Driver Easy.

Anyway, I vaguely remembered something about drivers showing up as unknown in the past and to fix it, I just needed to uninstall the driver and restart the laptop.

So I did that and it turns out, it was the touchscreen driver! The driver is back where it needs to be.

However, this did not solve the external display issue so if anyone has an idea on how to fix that, I would appreciate the help!

You can see that the laptop recognizes that there is a display hooked up, and the tv shows the HDMI2 icon, but the screen is all white. When I restart the laptop and plug it back in, it'll show the screen for a moment or two, but goes back to white quickly. I have also tried different orientations and modes (duplicate and extend.)

Also, I have tried other HDMI cords - same issue. I have also hooked up my work laptop and it does not have this issue so it is definitely an issue with my acer.

Glad to hear the touchscreen is back working.
Are you choosing project to second screen? (Love the wallpaper btw - a big 9th Doctor fan here).

I tried project as well both with both duplicate and extend and same issue.

Thanks, I found this beautiful fanart somewhere (can't remember where) and had to set it to my wallpaper. I love every reiteration of The Doctor... but 11 is my favorite. I just love him... he's a baby corgi. :giggle:

Is your other laptop a touchscreen also?
As the problem remains when you connect via HDMI then ensure the graphics card driver is up to date.

My love of Doctor Who began with the 4th Doctor.

Yes, my work laptop is another touchscreen - but that one is a chromebook.

The connection via HDMI was working today for my Acer...however, the touchscreen is back down. So it looks like there might be some hardware degrading going on. :(
