Lenovo Ideapad Flex 15 touch screen stopped working

I noticed my touch screen stopped working yesterday May 14, 2018. I have looked under Human Interface Devices and the HID-Compliant touch screen Properties window says "The device is working properly." I have also tried to update the driver, but the system says there are no updates available and that the only driver in existence is the original (June 21, 2006). I have also tried disabling and enabling the device and several restarts with no luck.

 

Any advice?

Hello Lenovocara

Thanks for using the Lenovo forums.


You could try to uninstall the driver, and then restart the unit and let Windows detect the driver for you.

See if this is able to help you out

Thank you for the reply, but yes, I have tried the uninstalling of drivers route several times without success. I'm still very much open to suggestions.

Re: Lenovo Ideapad Flex 15 touch screen stopped working

You'll find the HID-Compliant touch screen under Human Interface Devices now in Device Manager. I think they must have moved the device from its original position in the mouse section.

I'm having the same issue with losing the touch screen.  I deleted  the HID-Compliant touch screen, shut down and rebooted.  It worked for awhile then stopped working.  I read thru these posts and found one one paging down to the Universal Serial Bus Controllers and went thryu each entry in their, clicking on each one (I have 4 entries),  and seeing if there is a Power Management tab.  If so, click on it and uncheck the "Allow the computer to turn off this device to save power" option.

I unchecked the two I sound and the touch screen instantly came back.  Whether it solved the issue or not is yet to be determined.  I called support yesterday and they got it working by getting rid of the HID-Compliant touch screen and rebooting.  However, soon after I got off the phone it stopped.  I had some MS updates that failed so I did all the updates first, removed the screen driver, rebooted and it came back.

However, this morning it wasn't working again.  When it did as I said above in the Universal Serial Bus Controllers section, the touch screen came instantly back to life so you be the judge.  My issue has a three day window to get back to them if I'm still having problems so I'm hoping this latest change resolves my, and your issue.

Well, that worked briefly.  I left the computer on while I was out today and when I returned it was no longer working.

This is really hosed.  I tried again to delete the driver and reboot, still not working.  I'm calling support again tomorrow.

Re: Lenovo Ideapad Flex 15 touch screen stopped working

Yeah, I've done all the typical installing, reinstalling, removing of drivers and in the end nothing. I noticed the sceen did temporarily work a few weeks after I posted this, but then it went right back to not working. I've resigned myself to not having a touchscreen, which sucks, since I specifically sought a computer that would allow me to enjoy the benefits of a touchscreen. Good thing your computer is still under warranty. Mine isn't, unfortunately. Good luck and thank you for keeping me posted. Hopefully something works for us eventually.

I'll let you know what result I end up with, one way or the other.  Usually when electronics break theystay broke so I'm really thinking it's software.  That being said, I also have the larger Flex here and that one is fine so far.  I'm going to check if the MS updates have all been performed on that one. I'm guessing not since my gf uses it and I'm sure she hasn't checked.

Re: Lenovo Ideapad Flex 15 touch screen stopped working

The last thing I did last night was again go in and remove the checkmarks on both the power management options on the drivers within Universal Serial Bus Controllers.  I tried the touchscreen and nothing.  Closed the machine up last night, I normally don't turn it off, and when I got up it was working again.  This is the darnest thing I've ever experienced.

As I suspected, (and I was wrong, her machine is a Flex 2 15"), the Win 10 updates were not up to date.  I took the leap of faith and did the updates.  Her touch screen works fine.  So I'm a bit stumped.  I'm still planning to call support while the issue is still open.

Re: Lenovo Ideapad Flex 15 touch screen stopped working

Okay, I didn't call support since it worked all of yesterday, then it wasn't working when I woke up.  I was watching some youtube videos and someone mentioned ghosting connected to the touch screen issue and I recalled I had that problem intermittenly before this complete loss of the touchscreen.  Ghosting is where, for no reason, the screen bounces around on you like you are touching it but you're not.  It wasn't bad because it didn't occur all the time and it stopped so I really duidim't think much of it.  Anyone else experience this?

Anyway, this morning, I went back into the USB Conrollers section and put the check back on the two device settings that indicated power management.  I then disabled the screen driver, then uninstalled it and powered down.  When I powered up the touch screen was not working, went back into the device manager and took the check marks off the two device settings in the USB Controller driver.  I tstill wasn't working so I did a restart and it's back up running again.

After this fiasco, I decided to do one more thing.  I aw a Win 8 youtube where he went into the battery settings.  Right clicked on battery icon, right clicked on power options, left clicked on change power settings, left clicked on change advanced power settings.  Left clicked on USB Settings, left clicked on Suspend USB selective suspend settings and disabled on battery and plugged in settings.  Will see how this holds up today.

Re: Lenovo Ideapad Flex 15 touch screen stopped working

As I suspected after trying everything, it's a hardware issue and it's going back.  Either the  screen or the cable is the issue.  Somehow i suspect they may have had issues with this model.  I never used my machine as anything but a laptop. Never twisted it into those "flex" positions they market so that wasn't an issue.  It should be like cars that when a design flaw hits a certain number they have a recall or at least extend the warranty.  Another couple of months and I would have had to bite the bullet on repair costs since the machine was unusable without the touch screen.  I woul have had to use Edge rather than Chrome or Firefox since nether has a horizontal scroll bar.

I'm working on a Flex 2 that I bought for the gf after I liked mine much.  This one still works fine, just slower than he 5.
