High pitch buzzing when screen is on

[aaron98]

Hi,

My HP Envy x360 producing a high pitch buzzing noise, as soon as the screen comes on to when it goes off it is continuous.

I think I have narrowed it down to the screen making the noise because if I mute the speakers it still makes the buzzing, the only two ways I can get the noise to stop is by either turning the brightness down to about 8 (out of 100), the other way is if I press the keyboard shortcut to activate privacy screen mode, the noise stops very briefly while the screen is black then continues again when the screen comes back on.

The noise isn't recent, it has happened since the day I bought the laptop, but at first, I didn't notice it and once I did, I presumed it was only tempory. It has now been 12 months later and still no fix.

This obviously isn't ideal because the noise is incredibly annoying. Looking to see if anyone is having a similar issue or knows of a solution.

Thanks.

Aaron
