Reply for tomtom01:
1st and 2nd did not work in my case, but the 3rd seems Interesting! Is the prinsiple the same as disable and enable the touch driver? Are you using Windwos 8.1 cause in the folder "c:\Program Files (x86)\Windows Kits\8.1" I dont have "Tools".... (Im using windows 10?), so the .bat file is not work. I was unable to corect the location since i could not find "devcon.exe" in any other folders, so was not able to try it myself.

Ok. Seems like u theire are different touchscreen bugs.

 

The 2 code lines should disable and reenable the touchscreen device.

I forgot to  write that u will need to install the Windows 8.1 SDK. (Sorry)

It should be this download here: https://msdn.microsoft.com/de-de/windows/desktop/bg162891.aspx

Hello, 

 

Same problem. touch screen not working - no reaction to any touch by hand, but pen digitizer works fine. Tried all solutions described above by Tomtom1, no change. Also tried to start-up from USB with Win7 on the USB stick, no help as well.

 

Noticed the malfunction after upgrade to Windows 10. 

 

Any ideas what to do next? Any advise from Lenovo here?

 

looks like it is not a software related issue, but still hope it is.

 

BR

Dear All,

Its about 5 days that my touchscreen is working without any problem (after several restarting and shutdown and sleep ...)

I reseted my lenovo to its factory setting (windows 8) (the full reset that takes some time to remove and complete format everything) and after that I updated the windows 8.1 and then Windows 10. (about 1 month ago I reset it from windows 8.1 to 8 but with quick format not complete format and the problem was still there)

(P.S. Before that I tried eveything like bios update, any update that I could find for drivers, Holding power button for 20 seconds, ... but sometimes the touchscreen was responding and after a restart it wasn't responding at all - My pen always worked without any problem)

Hope your problem will go away too ;)

Thanks for the advice. Taken the amount of the re-install of different programs after full reset, as of now I better stay as it is, without touch working properly, maybe an easier solution will be found later.

Tried the solution "reza_e13" suggested and did the complete reset to factory setting with a total formatting of the SSD and everything, unfortunately this not fix my touch problems :( Will call lenovo tomorrow, and probably send in.

Hi, I got the following reply:

I see the thread you reference and know that the symptoms go back several years. We had escalated the case and worked it through engineering and the result was a firmware update https://support.lenovo.com/us/en/documents/ht079584

I realize there have been people posting and saying this didn't work for them, and there may be other causes including hardware faults.

In your case, since this happened during the Windows 10 update and others seem to be ok running Windows 10, I'm not sure how to debug this.

I would like to think it is just software, but without reloading back to a known good working configuration, that is difficult to rule out.

We may need a sample system and put another drive in it and reload it to test.

So i had the same problem after updating to windows 10, where the pen worked but no touch. Updating and reinstalling drivers, turning computer back to factory condition (full formatting) did not fix the problems. So i called lenovo and because my helix was still within warranty DHL picked it up at my door, and 4 days later (and thousands of km of travel) I received it again, with a brand new screen :-D! why didn't i just call lenovo a little earlier :P ?
