Emergency, need help (AW 17 R3 coil whine)

Today i noticed that my laptop is making an odd whizzing sound when a hardware component is doing something, like a hard drive readin/writing, a game running, browsing the internet...just about any activity, this sound reminds me of the copying machines at hospitals (that burn in the text onto this red paper).

It is highest in pitch during HDD reads/writes, and when moving the mouse or using the touchpad, but when playing games it's nonexistent (becomes more like faint white noise).

This sound is not normal afaik, i never noticed it before, but today as i was about to shut down the laptop i heard it from my chair and that got me concerned.

Here are a couple of samples

The pitch and volume vary depending on what's the laptop doing, in these particular samples i was simply moving my mouse with no programs running.

It's worth noting that when i turn on power saving profile, there is no such sound.

I still got about 5 days on my warranty, please advise.

Note: i recently bought a razer mechanical keyboard, idk if that's relevant but it's the only hardware component that i've recently added.

Edit: also, when idle there are often repeating ticking noise, like 1 tick per second for a minute or two, the sound also seems to be coming from somewhere in the front of the laptop (not the end with the fans)

 

If you're worried about the noise, call Dell and get them to replace your motherboard. You may as well use that warranty while you've still got it.

 

Its just coil noise and a lot of pc's have this. Luck of the draw but i wouldnt be worried. The reason why it doesnt happen when you are in power saving mode is because the pc never reaches full load. It often happens when the coils are under load and vibrate in a frequency that is audible. They always vibrate a bit by the way.

 

fan coil sound / HDD spin noise. obvious.. coil noise is just normal... anyways just get the fans/HDD replaced.. don't forget to backup.. and Wipe completely with multiple pass..

 

Emergency? Not hardly...

 

Exactly coil whine is a costmetic thing and just is annoying. It is by no means any indication of anything faulty or failing.
Also, fun fact. Some people are more sensitive to certain frequencies of coil whine then others.
For example I have had customers in the past that had gaming laptops where they could not hear the coil whine but their kids and wife could.
The only solution would be swapping parts under warranty in attempts to fix the issue.
Given you only have 5 days (at the time of the OP) I would be spending my time talking to Dell getting parts replaced.
Good luck!
