Multiple Lenovo laptops exhibit this issue and the company doesn't seem to care one bit. They could have fixed the issue themselves. Please just don't buy or recommend their products to anyone who cares about Linux. I've no idea who to ping or what to do.

I've heard that some modern laptops have some sort of I2C (?) multiplexors which need to be set up properly in order to enable keyboard input but how it all works, again I've no clue.

I'm CC'ing Mario Limonciello because I remember he knows something about that. Maybe he could chime in and give the instructions how to debug the issue and fix it all the affected people.
