Surface Pro 4, annoying noise from the back!

You can't.

Its mutter of being lucky I can say.

As I said i had 2 m3 version 1545 and 1549 and both had same level issue with that electrical noise.

Are you saying that for the two m3 versions, one of them was lot 1549? 

It could be that maybe at lot 1549 for the i5 version, something changed in the production

1.No fan at all, neither clicking.

As I said I m now having i5 not having that kind of issue.

Its kind a tiny mechanical noise that repeat over and over again.

Very annoying in quiet environment.

2.From the package will see 4 digit number near to the serial number for example lot 1549 meaning manufacturer date 49 week of 2015 ands so on. 

3.i5/4/128  I'm having now.

Take a look this review mention that they call it electrical noise

That is very interesting!  Thank you for that link, too - it is good to see a thorough online reviewer confirm this issue.

I found my lot number, which is 1546.  I wonder how we can confirm that this issue is resolved in lots after this one?  (for example, lot 1549)

Me too had that blizzard electrical noise with 2 m3 version.

One purchased from amazon lot number 1545 and the second one from MS store lot number 1549.

Returned both because was really annoying and not acceptable.

Never had similar issue with Pro 2/3 and Surface 3 2.5 years now I'm using surface tablet.

Now I'm using i5 version purchased from amazon lot 1549 and not having that kind of noise.

Thank you for your info, Alejandro1313!  A few questions:

1. Can I confirm that the sound you hear from the tablet is a high-pitched sound, and not a fan or clicking sound?
2. How do you determine which lot number you have?  I don't know how to do this.
3. Which i5 version are you using? (for example, 4GB/128GB or 8GB/256GB)
