Just recently I discovered that a keyboard doesn't do anything when I
hit one of these keys (german qwertz layout): qwer uiop 789+
They are all on the same row and I believe something broke inside the
keyboard (I remember vaguely it having let fall down off the desk).
Haven't investigated yet.

Maybe test with another external keyboard?!
