Dell xps 13 kaby lake mother board noise

I have a dell xps 13 9360 and for the most part ever since I have owned it the mother board has made a fuzzy noise when there is any movement on the screen, the noise is even louder when plugged in. I sent it back to get fixed and the issue was not resolved. I heard that maybe dell is trying to fix the problem. anyway I was wondering if a return of the laptop would be the best option since dell couldn't seem to fix it the first time.
