Dell XPS 13 coil whine, can it be fixed?

I'm just curious before buying something like the 9360, in case it has coil whine, can be "fixed" by the user, or it's some serious motherboard issue?

 

It's a result of the coil resonating at an audible frequency - it's a byproduct of the machine working essentially. Only way to fix it is either glue the coils or turn it off.

 

For 9350, all I need to do is to let it sleep and wake up, the coil whine would be completely gone.

 

Looks like the same issue with the iPhone 7/7 Plus, which had a hissing sound.

In some computers, when the processor is under load, you can hear a hissing sound on the headphones. I think it happened on the Dell XPS 9550.

where are the coils?

on the motherboard?

 

I was going to say stop putting your head on the keyboard. But I have a desktop in my motorcycle shop and get his through the speakers in between songs etc. But as soon as their is content coming through them, it either stops, or I can't hear it so it does not bother me.

 

I have a 9360 and it whines loudly. I have not found a way to fix it. The coil whine doesn't bother me all that much except if I'm using headphones.... Or, if I'm running linux. Much worse in linux. My theory is that the coil whine is directly related to how the linux kernal regulates power.

The 9360 does have this weird audio distortion issue. It goes haywire every once and a while. Best way to describe it, it sounds like it's trying to connect to a vintage dial up modem and then recovers. I'm assuming it's some kind of hardware or driver issue.

If you run the machine in Windows 10 at max power, it will throttle. If you run her conservatively, she will last for a long time and run cool.

Aside from those issues, it's the nicest laptop I've ever used. Super slim and light. Slim bezel.

 

Has anyone tried opening the computer and applying some kind of glue or silicone over the part that is vibrating? The issue can be caused by a physically moving component which vibrates for example, like a capacitor. You could theoretically prevent it from vibrating applying a substance over it.
