I just dripped some coffee on my keyboard. The humidity screwed up the
functionality of the right caps-lock key, the right CTRL key, the up arrow as
well as the middle row (4, 5, 6, +) of the numeric keypad. At first I thought
it was a software problem, but a reboot didn’t cure, so the coffee must have
burnt out some electronics. The left volume control key doesn’t work either.
