Swift 5 SF514-55T Coil Whine Issue

Hello everyone, I am facing constant coil whine issue on my new Acer Swift 5 SF514-55T ( i7-1165G/16gb ram/512 gb ssd version). A buzzing sound coming just under the processor and some high pitched whining noise somewhere around the middle of the laptop and these noises are constant (it is there even when idle). Plugging in something (for example a headphone) to the USB-C port makes coil whine disappear for some reason. Sound is not like screaming high, but high enough to annoy and distract me. I am not considering RMA because I don't think they will accept this as a problem and I need my laptop with me right now. Anyone else having this issue? As drivers can sometimes solve these kind of issues, will there be some driver update solving this issue?

Edit: I also noticed that:

When I move the cursor (by external mouse, by touchpad or by touchscreen), the crackling sound (which is there when idle) disappears.
Changing the power mode doesn't make that much of a difference.

I have found out that there is a newer VGA driver from Intel (version "27.20.100.9316"), but I am hesitated to update since this update is not present in Acer's driver website for Acer Swift 5 SF514-55T (there is "27.20.100.8783" version in Acer's website). Should I update? Can this driver update solve the problem which I am dealing with?

I have the exact same issue. And as you mentioned, it is fixed by touching the touchpad. I hope acer looks into this and fix it.

@AkshatKCan you record a video of the noise and post it on youtube?

Hi, I tried to record a video but the sound is too low, my mic does not pick it up

yes I can hear the noise. Is your laptop still under warranty?

Yes, I already made a service request. The service guy told me that it is just fan noise, he also opened the laptop and checked for any internal damage, there was none. He told not to worry about it at all.

Doesn't that sound like a noise coming from the fans? Did the technician replace the fan?

No, the technician did not change the fan. The noise is very very minimal, I cannot hear it from a normal sitting distance. If in future it does happen, I'll get it fixed

Okay, so yesterday I heard the sound again, it was really loud.https://youtu.be/FO9DWnQ8lWY, here the video, please have a look and help me out. I am not able to figure out what the noise is coming from, but it is definitely not the fans

I think it might be Coil's whine.

Bonjour.
J'ai également ce problème de coil whine sur mon swift3 SF314-511,le bruit disparait aussi quand on utilise le pavé tactile ou la souris,je pense qu'il doit y avoir une bobine de mauvaise qualité propre à ces ordinateurs...Ca me fait vraiment regretter Asus.
