PEBTAC 

Term used by system administrators and help desk technicians when an internal customer has a problem that no amount of technical/technological "fixing" will resolve. Stands for "Problem Exists Between Terminal and Chair"

IT Manager: The VP of Marketing needs help with his mouse again.
Help Desk: Well, we already replaced it with a newer model and updated the driver. This is obviously a case of PEBTAC.

Customer: I just got it and it's not turning on! : (
