XPS 13 whistling hissing noise from motherboard

Jump to solution

Does anyone else with a Dell XPS 13 hear a whistling/hissing noise that changes in frequency randomly? It's very distracting for me. A Dell engineer has replaced the mobo and unplugged the screen, battery, keyboard backlight, speakers and disk, So the noise has to be coming from the mobo. He told me that probably all XPS 13s make this noise, but I can't believe that I'm the first person to be driven crazy by it. It's not very loud, and if the fan is running it masks it. But in the dead of night without the fan running it's very plain and annoying even from a few meters away.

So far Dell has told me: "Perform these steps should resolve your issue" and linked to a massive thread about ALSA on ubuntuforums, which says to try millions of different things. (I did, nothing fixed the problem). (it's a Sputnik, but the noise is there in the bios so it has nothing to do with linux.) Interestingly I do not hear the noise while the diagnostics are running.

They have also told me: "We are working on an issue that seems similar to what you have." But as yet not replied to my request for more details.

The engineer said he unplugged the keyboard backlight. And it was still making the noise. Also it seems to get slightly louder when I plug headphones in.

I'm considering removing my ear drums. That's how much I love this machine. I love everything except the <ADMIN NOTE: Substitute character removed as per TOU> whiny hissy noise it makes that is <ADMIN NOTE: Substitute character removed as per TOU> driving me crazy. And I'm not happy that Dell wasted my time by sending an engineer to replace the mobo when they knew it was gonna fix it. So what's the closet thing to it? Must run Linux good. Lenovo X1?

I have a Dell XPS 13 Haswell, and it also hisses. It's worse with the keyboard backlight is on. It's also triggered by some USB 3 products plugged in. 

I have a Anker 3.0 USB hub plugged in as kind of dock, so now the machine hisses constantly. It's very annoying. 

I suspect the issue is due to electromagnetic interference (EMI), which could possibly be solved by better shielding.

The potential for USB 3 to cause EMI is well known. Intel has a whitepaper about it:

http://www.intel.com/content/dam/www/public/us/en/documents/white-papers/usb3-frequency-interference...

Dell should know better. 

It particularly ruins sitting in a quiet room with the laptop, where all you can here is the focus-destroying laptop hiss. 

I expected better from a premium laptop and will reconsider purchasing another Dell in the future if this goes unresolved.

I have had my XPS since June 2014 and today is the first time I noticed the noise.  I am sure I would have noticed it earlier as I work all day in a fairly quiet area.  This post pointed out the USB 3.0 hub issue.  I had recently plugged in a Sabrent USB 3.0 4-port  hub just the other day for some quick USB access for a camera.  After reading this I  unplugged it and the annoying sound went away.

I have the Dell high speed docking station / port replicator that I normally have all my extra's plugged into - the Sabrent is a small portable one I take with me on the road.  I don't notice the noise at all with the dock.  It could be that the dock is far enough away???

I do use a wireless USB mouse and keyboard with a dongle plugged right into the laptop - that doesn't seem to be an issue and I have not experienced any degradation in performance with those devices (this was mentioned in the article).

I have really enjoyed this machine so I am glad I found a solution here!  Thanks for sharing!
