Update: Problem still exists. However I managed to get touch-pad back to
work after putting my Yoga laptop to suspend mode and back on. After the
power is restored the touch-pad works. After full power cycle (power off
and back on) it is again in non-working state.
I have also reproduced this several times. Suspend mode is applied with
System power settings -> Ac power -> Laptop lid closed -> Suspend and
then closing the laptop lid. Wake-up from suspend is managed by opening
the laptop lid. After wake-up the touch-pad is working.
This may be either something related to system boot-up after full power
cycle or then laptop lid sensor signal handling issue.
