YOGA 720 15IKB Touch Screen Problem [VIDEO]

2020-09-17, 18:13 PM

Pen works fine, but touch screen stopped working. 

 

I checked the device manager, it says "HID compliant touch screen" is working. Tried to remove and reinstall the device, but nothing changed. Also tried to update the driver, but it says I have most up to date driver.

 

What else should I try?

 

 

EDIT:  I saw this video and tried to draw on the middle right part of the screen, and I've found out that I have the exact same problem.

I have the same problem as you do, and I've tried all kinds of ways to deal with it...

reinstall, updates the driver, delete the win10 updates, flash the bios...

still not working...

U get it solved?

I couldn't find a solution although it looks like it's a very common problem because I found lots of similar complaints dating back to 2017-2018, but there's still no confirmed solution anywhere. So I think it's a hardware problem :(

Threre should no reason that cause hardware faliure... 

I noticed that the surface pro also have touchscreen problems after win10 updates, someone even have their screen replaced and the problem still exists.

BTW, I found a solution to thinkpad yoga from the thinkpad forum, a micro-code updates...but I'm not sure whether it works on yoga720 or not.
