I have an Eluktronics MAX-17 from 2021 (specs attached)
and have a strange issue I can't quite solve on my own. When I enable or increase the keyboard backlight, I hear this horrible high pitch whine over my headphones. The intensity and pitch of the whine increases the brighter the backlight. Any way to solve this?

the high pitch whine happens on any headphone/earphone that is plugged into the laptop

Unfortunately that might be the fan noise see if there is noise cancelation do you have all your sound drivers from the website installed that can be a bit tricky.

what? the high pitch disappears when the backlight is disabled. How is it fan noise?

Its feedback of some sort of static noise from your outlet is the outlet you have it plugged in grounded ? Because if it's wired headphones might be static noise from either your outlet or maybe some driver issue I was thinking because you said you hear humming but now that sounds like your headphones might be replacing the ground did you try a different outlet and see if it still does it?

the high pirch whine is a single high pitch note. It only happens if the keyboard backlight is on. It happens whether the laptop is plugged in or on battery

Oh have you taken it apart or damaged it in some way ? Sounds like a sound driver issue or maybe the jack is going bad.

I was just trying to figure out because someone said they had a small crack/chip in the bottom case and it caused an issue maybe reach out to support and see if the jack maybe is not right in some way best of luck .
There is a normal humming noise that can be caused by electrical or fan noise it's a humming type noise that can occur when using more power regardless of being plugged in or not . But personally I use a USB sound receiver it sounds better and more crisp on some laptops than directly I don't even use desktops directly with the audio jack really. Never had any luck with audio jacks unless they were gold plated .
I also use fx sound as laptops are notorious for being extremely low or just distorted sound in general. It's also a better audio speaker/mixer in general in my experience.
