Hello! Tell me where to dig. The story is like this.

The Huawei Matebook D15 laptop (almost new) sometimes emits a quiet, thin creak (or maybe even a squeak). Something like wet rubber rubbing against something. It sounds very quiet, barely audible.

At first I thought it was a cooler. I changed it and bought a new one, but now it turned out that this sound did not disappear.
I now listened and realized that the sound comes from a completely different part of the laptop.

There are no other moving parts in the laptop. Tell me, what could it be?

as an option, the magnetic circuits of the power converters whistle.
magnetic circuits are made of two halves and glued around the windings. if the seam is bad or "loose", then due to magnetostriction, the parts begin to vibrate and produce sounds.

It is quite possible that the body creaks due to backlash (loose fitting of body parts to each other). Not scary.

Laptop on SSD? not HDD?
