P52 - ELAN touchpad malfuction (beta firmware) - any plan for releasing new touchpad firmware?

2019-06-21, 7:53 AM

This time ELAN touchpad doesn't perform left click action after a single tapping. (suddenly)

Other function is just fine. 

I am running my work so I can't reboot system right now, therefore I'm not sure reboot would fix the problem.

Disable and enable touchpad in windows 10 setting, disable and enable ELAN driver in device manager doesn't work for me.

My touchpad firmware is beta version now. 

I am wondering when the official new version released?

Installed beta firmware is even newer than the latest firmware on the site. 

It was released unofficially by lenovo staff in this community.

So weird it's still version 02 in my country (korea).

But when I change the language to "English", and set country to "US", I can see the version 03.

Thanks~
