Newbie needs help wie keyboard

I am quite new to Ubuntu.

I am running Ubunutu 22.04.4 LTS on a Lenovo Yoga Pro 9 16IRP8.

Install and everything is fine but I am hav ing troubles with the keyboard hereand then. Specially when I just close the lid and open it again it does not work.

I have tried blacklisting Intel specific drivers which enable sort of a "tablet mode"but still. Here and then it does not work at all.

Any permanent solutions?

Best
