Dell XPS 13 (9380) - Buzzing noise when AC power connected

I bought a Dell XPS 13(9380) a month ago and recently I noticed a buzzing noise when my AC power is connected. I try to connect it to another socket but the problem still exists. I do not think that this has affected the functionality of my xps, but it is pretty much annoying, especially when I am in a quite place. Can this problem be solved?

Yes. My XPS9360 also has the same problem when plugged in AC, even sometimes buzz noise comes with no reason. Also, I don't have any clue for it...

I'm also have very noisy adapter. I solved this with changing to smaller Apple 30W USB PD charger. Now is total silence. BTW 9380 supported USB PD output, so you can charge your USB PD iPhone (like X or Xs) from your XPS as fast as from wall charger.
