    You know when we have weird things like this happen on desktop pc first thing we check is the PSU. Could is be the Charger itself? I did notice once it does get hot and i thought i saw a made in china sticker on it or was that the usb dongle. Do you have another charger you can check with? I won't be able to test this till tomorrow.

    I use a Google 45w charger at work, not sure I witnessed any different behaviour. One thing I'm sure is the Google charger is a lot better since it charges my Note 8 without a problem. The Dell one also charges but would freeze the screen often so I had to unplug immediately so not to fry my phone.

    Can any of the new XPS 9370 owners please confirm that their laptop is absolutely coil whine free when plugged into AC? I am just trying to find out if all units are affected on one level or another.

    If there is a chance to get a 100% coil whine free unit, I'll just keep exchanging them :)

    ok its not the charger or the battery.
    i'm going to buy a new Samsung ssd today and re-install windows. I'm thinking its a driver conflict. Also when i saw my toshiba ssd half the pcb looked new and clean and half looked old and used, weird?

    Also i think i found a way to reduce coil whine, will do more test today.

    ps when you open up the laptop be careful the metal is very sharp around the edges. i cut one of my fingers real good. Thanks dell
    thanks dell for all the extra work and wasting the one day i have off

    Can anyone confirm that 9370 Silver/Back 1080p (FHD version) has glossy Edge-to-edge Corning® Gorilla® Glass 4 screen instead of that matte bezel that was on 9360?

    Ok, from what I am reading here, you can only hear the coil whine when you have your ear to the keyboard. How often do you use your computer like that?:bigconfused:

    That's totally how I use all of my computers. Makes it harder to see the screen, but I think it makes me look cool.

    Haha, try reading the rest of the sentence next time :)

    "Without the cable plugged in and with battery settings set at "Battery saver" or "Recommended" I can barely hear it even with my ear pressed to the laptop and I believe that should be the "acceptable level", but the second I plug it in it starts and never stops. Touching the screen, downloading files (this especially), watching videos, even scrolling web pages - I can hear the coil whine from 5 feet away. "

    Did "5 feet" confuse you? It's 1.5 meters in proper measurements :)

    Ok guys quick update.
    I tried different charger, Same problem.
    I tried without the batter just charger plugged in. Same Problem.
    I bought new SSD and reinstalled windows still same problem.
    I turned off all the options in bios. Still over heating and fan problems but helped with the coil whine but all those options are important so thats a no go.

    I'm sending my Laptop to Dell's Lab for further testing.

    I have the 4K version, currently running a dual boot windows/ubuntu and I can't hear any coil whine when plugged into AC, even when I stick my ears close to the left side of the keyboard.

    I do however get the fan issue (fan starts running when plugged in AC), much more pronounced on Windows than Ubuntu.
