    I have the 9350 and I have the coil whine too. i5 processor with intel graphics only.
    The last laptop that had this whine was a really old Vostro from like 2009 or 2010. My other laptops never had it. Really annoying but I'm learning to ignore it. It's not as high pitched as the Vostro lol.

    I had a look at my second PSU, which is the newer unit without the buzzing. This does not help with the coil whine of my XPS. Today a technician will come and swap the mainboard again. I will report if that helped and if I actually got the second revision.

    Any luck with the "newer revision"? For some reason I have trouble believing this. Dell has proclaimed they have "fixed the issue" several times in the last few years on their XPS line, but it seems 50%ish of units still have it, including the new Kaby Lake model.

    I feel like most, if not all XPS units have it. My 9350 has it. It was annoying at first but I got used to it

    Edit wow I didn't realize that I already replied here lol!!

    Sorry for the late reply! I was busy with life.
    I actually got a newer revision of the board, at least regarding the serial number. The high pitched whine is gone with the second replacement board, but some muffled whine is still audible. Considering the two boards I had before is the third one a major improvement for me. Even muffled coil whine is sometime audible, thus I am still not sure if I should be happy with it or not. In the last few week I was at least not annoyed by my XPS as with the board before the current one ^^

    You will never get rid of coil whine, quit while you are ahead. Every silent laptop will have some form in a silent room with these chips.

    This guy claims that coil whine issue was resolved when he upgraded the SSD on his 9350...

    I am not 100% sure but the coil whine seems to come from two places.
    One is the upper left corner of the keyboard (even when the laptop runs on battery).
    The other is from under around the touchpad. It is super noticeable when I compile my Android app, which involves reading/writing a huge amount of small files.

    So I guess changing SSD will address the later source.
