Narrative:

After arriving at the gate; just after [we completed] the parking checklist; the APU auto shutdown with a fault light. The ground power was hooked up at just about the same time. Ground power was selected and the APU switch turned off (the fault light remained). The first officer called maintenance and wrote it up on ACARS. There was no indication of fire bottle discharge at the time I left the airplane. I was called several hours later by the flight office to see if I had any info on the bottle discharge which was the first I learned of it.

Original NASA ASRS Text

Title: A B767-300 Captain was surprised to be advised several hours after his flight that maintenance had discovered the APU fire bottle was discharged. The APU had 'faulted' and automatically shut down after arrival at the gate but the flight crew was unaware of any bottle discharge.
