“Fejl 40” (Error 40) is a Danish/Swedish expression normally used among computer technicians or helpdesk workers. It was originally used by technicians who came to inspect a system and then called home to report that the error had been identified as an “Error 40”. It means that the error is positioned 40 centimeters from the console. In this way, the technician could tell headquarters that it was a “User Error” without angering the “stupid user”.
Today, almost everyone in Denmark and Sweden will know that it means the same as the English expression PEBCAC (Problem Exists Between Chair And Computer). I suspect this error is responsible for at least 90% of all “computer errors”. 😉
