Surface Pro 4, annoying noise from the back!

Anonymous

Can someone explain why the back of my surface pro 4 (only when the brightness isn't 0% or 100%) makes a noise?

For example, when it is on 25% of brightness it starts making a strange noise slight like a whistling...

Can someone help me?

I want to point out that I started a separate thread about the modem-like screeching noise which may be related to c-state but which is not related to brightness level like this thread is. Someone has since merged my thread into this one but they are not the same issue!!!! VERY CONFUSING AND WRONG

Yes you are right! My cousin has it too and he has the same "problem" that we all have.

I hope that Microsoft and Intel will update to delete this issue...
