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)

Let's block ads! (Why?)
