Surface Laptop 3 Faint Buzzing Sound

Hello,

I’ve got the i5 8GB Surface Laptop 3 (13.5-inch), and today, while browsing the internet, I noticed a fairly faint  buzzing sound coming from under the keyboard. It was faint enough you couldn’t hear it from a couple metres away, and sometimes buzzed continuously, other times buzzed in short repetitive bursts.

It didn’t sound like the fan to me, so I opened up the task manager to see if browsing was straining the computer in some way.

I have updated the computer completely, but the buzzing persisted.

Is this a normal electronics problem? Is it actually just the fan? Or is it possibly a defective unit?

Edit/Update:

I took the device into the MS Store today to see if there was something wrong. The staff took it into the back and tested it. They found increasing the computer's workload caused the sound to increase and described it as a popping static-y sound. They replaced the device and I have a new one now. Unfortunately, I've found through usage that this one is also making the sound. I am waiting to see if a firmware update reduces the noise since it seems pervasive across the devices.

    Ditto here - mine is now technically out of warranty although this is clearly a manufacturer's defect affecting this entire lineup.  

    It's (unfortunately) incredibly agitating......this little "buzz" has me completely re-organizing my home office setup just to get the laptop OUT OF EARSHOT.

    I booted into Win10 Safe mode where the processor frequency is fixed to 1.5Ghz and voila, no buzzing sound at all!

    So it is definitely the speed stepping of the processor causing this buzzing issue.

    At least this let me hope that it can be fixed with an driver update.

    Yes, maybe they can fix the issue with a driver update. But for me, it looks more like a hardware issue...

    just noticed that when you go into the BIOS the Buzzing sound is completly gone. 

    Means to me that it has something to do with CPU/ Power Mgmt, Speed step drivers

    while chaging the pitch of the realtek speaker, it stops buzzing....
