Electrical noise coming from the center of the laptop

I’m hearing an electrical noise coming from the center of my laptop. It sounds like voltage jumping over a small gap.

It’s not related to the fans.

this is the noise. Ignore the birds chirping in the background:

The noise is coming from this area of the laptop:

Is this normal behavior, or should i have this looked at?

Could this be resolved by unplugging and replugging certain connectors?

Either way it needs a thorough clean. Download the service manual PDF www.dell.com/support/home/en-uk/product-support/product/xps-15-9570-laptop/docs carefully clean it. May be some short circuit is happening, Clean it well..

Not sure I heard exactly the sound you’re getting at. I had a problem back in the day which had to do with speed-step. Disabling that in the bios helped. It was a sort of electric sound from the processor. Highly annoying. can’t say if it’s the same sound you’re experiencing.
