Touchpad makes an "electric" sound when plugged in

Options

This sound is not loud but I can still hear it and it is annoying

I definitely sounds just when the lap top is plugged in the A/C charger and touchpad is on

Any easy way to fix it?

I have an Acer ConceptD, still under warranty

    What is the exact model? Example AN515-55-58VH. Can you record a video of the problem? Are all your electrical outlets grounded?
