I recorded the sound of the DELL AC Adapter that make a very high pitched noise (3000 Hz) each time it is plugged to the computer.
The sound is audible in a quiet place, but for this video I have to approach the adapter to the computer microphone (located at the webcam), record this hisss sound with Audacity and play it again.
The computer is a DELL LATITUDE 5401.
The AC adapter is maybe 3 years old. Reference, as indicated on the sticker : HA130PM160 ; DP/N 0P7KJ5.
