Dell Inspiron Touch screen not working

[JoeTech]

I have a Dell Inspiron 7348 where they said the touchscreen stopped working after an update. I looked in the device manager and the touchscreen isn't even showing up. I looked under I ran the dell diagnostic test and support assist app and both don't have recognize the touchscreen either.

I looked under Human Interface devices, Usb controllers, Mouse and other pointing devices and also set it to show hidden devices and still nothing. I took the laptop apart and made sure everything was connected securely. I even put in a different hard drive reloaded windows 10 using both 1709 and 1803 builds. It was already on the most current bios. I downgraded the bios to an earlier version and reinstalled build 1709 and still the touchscreen is not working.

There are lots of articles like this one that says that the touchscreen drivers just disappeared after the update similar to my problem where they can't uninstall the touchscreen driver because it is not there.

The only thing I haven't tried yet is ordering a new touchscreen to test but figured I would ask if anyone else would know what the problem is before doing that.

Does it work in Linux?

Don't order anything yet. First did you "show hidden devices" under Device Manager? Does it work under Linux? Also 1803 has been cratering a lot of drivers. We have an Asus X52U laptop that 1803 has removed the DVD function.

If you have masochistic tendencies you could call 1800-MICROSOFT and have them TRY to fix it since they broke it. They will help you.

I tried it in linux mint 17 and windows 10 pe from USB and didn't work. I even tried this from a different thread by another tech here.

"Open the System applet in the control panel, click advanced system settings to get the system properties window, go to the Advanced Tab, click the Environment Variables button at the bottom. Create a new system environment variable named DEVMGR_SHOW_NONPRESENT_DEVICES and set it to a value of 1.

Then launch Device Manager, go to the view menu, and enable show hidden devices. Windows will now list each and ever stupid driver installed but not actually being used at the time. You can go through all those hives and cleanly uninstall every ghosted icon. This includes busted shadow copies by the way, which can pile up if you're using any sort of real backup."

I'm not fully sure it is the screen though and it will be hard explaining to them how that could happen after an update. I could call Microsoft but I'm sure I could get a new screen in and tested faster and with less frustration then dealing with them.

I tried it in linux mint 17

Mint 17 may be older that the laptop, so may not have a driver for the touch screen. Try it with a current version Linux.

When I get weird Windows things happening (rare for me), I pull out a spare small SSD and do a clean install to that and see if it is a Windows issue or not.

I downloaded linux mint 18.3 and was not able to get it to work either. I guess I could try the latest ubuntu release

I did do a clean install with a spare hd using both 1709 and 1803 builds and also different bios versions. I don't know what else to try at this point.

I'm going to go ahead let them know they need a new screen. Thanks everyone for your help.

I always believe a non working touchscreen is a bonus. I hate and always encourage clients not to get them.

After all this diagnosing, I mentioned the cost of a new touchscreen and she said "No thanks it's not that important to fix" and is just going to pick it up. I agree that touchscreens are just one more headache to deal with.

You know that even Windows Updates can't break your hardware, right?

Would you put money on that?

Rare, but can happen.
I've never had it personally but have heard of others having it happen to them.
