P2419H, buzzing when turned off

Question

Is it normal that to hear a constant buzzing from the P2419H power supply when its turned off? As soon as I turn it on the buzzing stops. It's not too loud but still annoying at night. So I must unplug it from the electrical outlet.

Please reply to the DELL-Cares virtual assistant private message with the P2419H service tag number.The P2419H only ships with a power cable, not an external AC power adapter. So when you say, 'P2419H power supply', you must be referring to the P2419H itself? That when plugged into wall power outlet, but turned off via its power button, you hear a buzz originating from where (side, bottom, back) on the P2419H? Can you record a video and post it so Dell can hear this buzz?
