XPS 13 9380, AC adapter connected, buzzing noise
I bought a Dell XPS 13(9380) a month ago and recently I noticed a buzzing noise when my Delta 45W AC adapter 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 quiet place. Can this problem be solved?

Yes. My XPS 13 9360 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.

Read this first. I'm also have very noisy 45 W AC adapter. I solved this with changing to the smaller, lower wattage (non-tested/non-validated by Dell) Apple 30 W USB PD charger. Now is total silence. By the way, XPS 13 9380 supports USB Type-C PD (power delivery) output. So you can charge your USB Type-C PD iPhone (like X or Xs) from your XPS as fast as from wall charger.
