That doesn't look like a touch screen. (I don't know how windows figures out that it has touch capability. On the touch models, the T440s designation is lower down and the bezel looks different

There is a model of T440s that support touch screen, the bezel is integrated with the screen and it is glassy not like the one I have in my model it is a separate bezel. But windows still shows the compatibility of the tactile.

Touch is an option on T440 and T440s. Most don't have it. On all the screens, touch and not-touch, the frame around the screen is bonded to the panel. On the non-touch models, this frame extends all the way to the bottom. The designation (T440s) is printed on the screen frame. On touch models, the bezel is a narrow, gray strip across the full width of the screen and the designation is printed on the bezel. The glass surface on the touch models contains a matrix of thin wires making up the static discharge digitizer. Regardless of what windows says, if you don't have the glass digitizer, you don't have touch.

I have a T440s 20AQ that should support touch. After upgrading to Windows 10 I lost touch functionality. I've tried manually updating drivers and deleting/auto refreshing installing drivers in device manager and no success.
Do you know is there a firmware update for these lcds similar to the Yoga Models?
