Some laptop keys are not responding anymore

Some keys on my keyboard suddenly stopped working since the last boot. Yesterday everything was still working fine and I didn't change anything since then on my computer.

I used "xev" to check if arch receives any signal from a pressed keys. While most of them showed results, pressing a few buttons (e.g. 'b' or 'n' or some arrow keys) didn't show any results.

My system is up to date, and I use xorg as my display server.

journalctl -p 3 -b gives this result:

Re: Some laptop keys are not responding anymore

Boot into a live medium and see if they work there.

Arch + dwm   •   Mercurial repos  •   Surfraw

Re: Some laptop keys are not responding anymore

I tried it in a live medium, was not working neither. I guess the problem lies in the hardware...
