I disabled the Touchscreen of my Lenovo X220 (core i7) tablet due to over-sensitivity (it registers some non-existing 'touches' itself) in the Device Manager according to this previous post:

How do I disable the touch screen on Windows 8.1 for a Lenovo X220?

It works right after I have disabled it. However, as soon as it has entered a sleep mode or a hibernation mode or has been rebooted, then the touchscreen is automatically enabled again. It wasn't like this before, and now it is quite annoying because my X220 is set to sleep with a 5-10 minutes idle time.

Has anyone experienced this? Or is it just some kind of Lenovo driver update / plug-and-play issue?

Thanks in advance.

P.s. I am running Windows 10 x64 with all the latest windows updates and Lenovo updates.

  • run devcon to disable the device when windows resumes again. this can be done by attaching a command to the event that gets raised when windows resumes. Feb 7, 2017 at 17:16
  • What do you mean by "devcon"? Is that a Windows command in windows paths?

  • So I have to install DevCon in Windows 10 first. (keepthetech.com/2016/07/install-devcon-tool-in-windows-10.html) My question is also that why this (the device automatically re-enabled) was not the case a few months ago / before some Windows updates.

  • ms released several updates, so one of them broke this. use event 1 of "Power-Troubleshooter" Source and run the command here superuser.com/a/276095/174557 Feb 8, 2017 at 16:25
  • So I tried to find out how to install DevCon and I am quite surprised that I need 12+ Gb disk space just to have a command line tool that helps me to re-disable a device driver every time when my laptop wakes up. Reason to need 12+ Gb space is that DevCon (Devcon.exe) is included when you install the WDK, Visual Studio, and the Windows SDK for desktop apps. And the first step, when I chose the smallest express version is already 12+ Gb ...
