Windows 10: Rotation Lock Grayed out or loss of Touchscreen Functionality on Lenovo Yoga Windows 10 laptops

Hi everyone

I noticed a lot of locked threads, regarding users of Windows 10 with Lenovo Laptops, who are suffering the grayed out screen rotation setting, and/or touchscreen loss;

the issue is because of a process called ymc.exe Yoga Mode Control, found in process manager

just open process manager to deactivate the process and not allow it to activate automatically switch off , byright clicking on the process itself in the process list. It is responsible for both grayed out lock screen, and loss of capacitive touchscreen functionality. To ungray the screen lock, simply deactivate YMC.EXE

But the touchscreen loss may or may not come back when a Windows update happens. If you delete ymc.exe. the laptop works fine, but Lenovo Updates will replace it again.

rotation lock grayed out on Lenovo Yoga laptops solved

Hi i wanted to share my discovery of why all Windows 10 lenovo Yoga touchscreen laptops have the rotation lock grayed out sometimes and cannot reactivate;

if your rotation lock button in action center is grayed out like this





Go to Task Manager (press ctrl + alt + delete), and click on the services tab, and look for
ymc process (ymc.exe = Yoga Mode Control, which is the culprit, and it happens when you rotate your screen to portrait mode)





Right click on ymc, and stop the process. Leave it that way. Your Rotation Lock will remain unlocked now. It was a mid-late 2018 update from Lenovo which made this ymc cause the grayed out screen rotation lock. The computer works fine without this process,
and in fact, it is precisely this process, intended to sense when to change to tablet mode and back to laptop mode when folding the screen, which causes the issue. There will be no adverse effects from deactivating this process. If you deletre it, Lenovo will
put it in your next update and it will reappear, so best to just 'stop' the process.
