Once I remove the usb dongle the noise disappears as others seem to have mentioned
Screen brightness didn't seem to affect the noise at all in my case
I'm running manjaro i3 (20.06)
OMG you're right as soon as I plug my mouse I hear this annoying whistle noise coming from the power jack (doesn't change if the charger is plugged or not).
I even noticed the noise is much lower for few seconds when I lift my mouse up the desk but then the mouse's LED is going into a power saving mode (I believe) and the noise is coming back
I switched from the original Debian + Mate to Manjaro + KDE and I never noticed this noise before. Only now...
This is quite annoying because the trackpad is really hard to use so a mouse is basically required, especially for coding (sorry I don't know the magic VIM key tricks yet).
Is someone experiencing this issue with Debian + Mate?
I'll probably give it a try from the SD card when I've a moment.
Actually I just noticed something.
If I plug something else on the second USB port the noise stops.
I think from now on I'll always have something plugged on both ports then
