Hi!

I just recently got a new laptop (Acer Swift 3). In quiet environment i can hear this weird almost radio-like but higher pitch noise, usually under some load, but not necessarily.

This is the audio clip (disregard the first 10 seconds, I accidentally bumped my phone into laptop)

You'll probably need to raise the volume to hear it though

I'm interested what is that sound (not the fan noise). HDD is also excluded. (SSD laptop)


Thank you for your help in advance

Well about the only thing you can do is return it and see if the new machine has the same issue. Personally I wouldn't want to rip a laptop apart to figure it out but that's just me.

That sounds like coil whine or a fan. Are the speakers turned all the way down? Do you have anything plugged in at the time it's happening or are you completely wireless?

The speakers are off and nothing is plugged in.

If you have to hold the microphone close enough to the laptop that you accidentally bump the laptop with it then the noise is not very loud. In all likelihood that sound is just normal fan noise.

Well, i recorded the sound near the screen, fans are on the bottom of the computer on the lower side (nearer to me). And its very distinct sound, like this high-tech sound if you understand me, not some fan spinning.
