my 64gb surface pro has a static noise that is very quiet, can only be heard in a quiet room. its high pitched and constant when powered on. though its very minimal but the noise like this really starts to annoy me. its not the fan noise and is not affected by what I do on my surface. sounds like electric current noise.

did anyone notice the same issue?

I was using my RT earlier today and it is absolutely silent while running! then I turned on my pro, there it is. that not very loud but definitely audible electric current noise!

its a hissing sound, not from fan, but sounds like from motherboard.

Strange, I don't recall making this post...

Disregard. Thanks.

Mine has the same high pitch noise you're talking about
I'm guessing it's emitted by the fan
I wouldn't worry too much about it

thanks for confirming this!

Hi there. I have this problem too. Any luck in reducing this sound? It is quite disturbing to me, when using it to study ):

Its like living next to an airport. One would think you'd eventually get use to it to a point you don't hear it anymore.

Does it go away when you turn off the Bluetooth? I had a laptop that was doing the same thing and it went away when turning Bluetooth off.

Mine also has the problem. Disabling bluetooth does not solve it
The hiss is very clear on the back of the unit

Mine has it too, got it exchanged at first... the new one has it aswell. I can't ignore it. :( This saddens me. Alot! Don't know what to say to MS.

Nothing on a 128Gb version, the only time I hear noise is if it's doing a lot of processing and the fans kick in other than that nothing.
