Strange keyboard problem on thinkpad edge e531

The problem is a wrong keymapping on the internal keyboard of this laptop i first noticed about a week ago. The keymapping in general seems to be OK, working german umlauts, but some keys not working properly, e.g the "r"-key giving an "l", etc. . I also checked with xev that the FN-Key, which in combination with ESC is used as FNLK to toggle between F-Keys and special keys for mute, volume, brightness, etc. doesn't produce any code anymore. I've looked through /var/log/pacman.log but found nothing at that time i would concern being responsible for the change. An attached USB-keyboard works without any problems, all keys are recognised. I'm not quiet sure if it is a hard- or a software problem, i can't check with windows because i don't have any.

Things i already tried, beside an external keyboard:

- Boot to emergency.target gives a normal german keymap with all keys working as expected, but can't ckeck F-keys there
- Blacklisting thinkpad_acpi also gives me a full working keymap, but can't toggle F-Keys because of no functional FN-key

It worked without any problems the last four years and from the points i explained above, i suppose it's more in the direction of software, but i'm really not shure about that.

Any idea or help is really appreciated, if you need more information, just ask

To get an idea about the thing i'm talking about:
