Shortcurcuit?

[Kuhluh]

Hello,

so I bought a Pinebook Pro. It's nice, but I noticed that there is a very high whimpering (?).
You probably won't even here it if you are older than 25 (yep, that high).
Because it's a bit annoying I opened it up and noticed what you see on the picture.

Now, is this normal? And could that be the cause? If not, any ideas for the cause?

OK, because attachments didn't work (or at least I didn't find it), here a link: https://cloud.khanich.de/s/NnaLAwYbRDnqXRY

Likely it's coil whine. It shouldn't be anything to worry about, and is known.

OK, so then I will mark it as solved.
