CategoriesTechnology & Computing

PEBKAC stands for Problem exists between keyboard and chair, a computer abbreviation.

Help-desk joke meaning the fault lies with the user rather than the computer. IT staff use it among themselves for issues such as unplugged cables, a monitor switched off or Caps Lock left on.

Example: Ticket closed: the monitor was switched off at the wall. Classic PEBKAC.

Usage notes

Variants include PEBCAK (problem exists between chair and keyboard), PICNIC and "ID10T error", written so it looks like a technical code. The joke is condescending, and professional support teams avoid it in front of customers. Network engineers have an equivalent, the "layer 8 problem", referring to a nonexistent layer above the seven in the OSI model.
