Title:
Touchpad not recognized in laptop Lenovo Thinkbook 15-ILL
I also have a problem with my trackpad.
I put various BIOS updates and tried to fix this bug according to descriptions

appear in /proc/bus/input/devices
I found in Bug-Report #1853277 that Kai-Heng Feng stated "We are

I tried v5.7.1 kernel and it looks the same as with mainline v5.8.0 and
my initial 5.4.0-39.
The part described in comment #13 still looks the same in logs.

Bug 1885573 (https://bugs.launchpad.net/bugs/1885573) marks this one as
duplicate, but installing kernel 5.7.1 or 5.7.7 didn't work (though I

evaluated. The _REG methods initialize some variables to make touchpad
work.
Please test latest mainline kernel:
