High-frequency noise problem when turn on keyboard ligths on my HP Victus 16

[Mazila]

When lights on keyboard is on it's have high-frequency noise. The noise is gone if lights is off. Connecting USB devices reduce noise but do not remove it completely. Is there a way to remove it without connecting USB? I quite need those ligths but this sound is really annoying. Notebook HP Victus 16-e0078ur (4E1L0EA).

@Mazila,

Interesting problem -looking in various blogs, you're certainly not alone, apparently.

One suggestion to try: choose the white light option if you can with brightness down.

You may want to read this related HP Forum discussion thread: https://h30434.www3.hp.com/t5/Notebook-Hardware-and-Upgrade-Questions/high-frequency-noise-problem-w..., where the keyboard noise is described as, and I quote:

"Unfortunately, the "high-frequency noise problem" you are referring to is coil whine - a PC user's biggest nightmare.

This is a result of a lack of quality control of the motherboards in the HP Spectre x360. I have already witnessed and experienced several motherboard failures. The coil whine may be related to the PSU - however we can't be sure."

The response goes on advising the user to contact HP support.

Kind Regards,

Thanks for answer. Sadly i only have off/on fucntion for ligths. Maybe there is programmatic way to lower brightness? Other treads that you mention is not helping too.
