Hi, here's finally the pics:
This includes all sockets (2) to be found in by bedroom. The second pic contains the socket where I plug the whole thing. The third pic contains the socket where I plug the bed lamp. It looks like trash but works.
The interesting part is that as you can see on pic 2, the socket has a cable that goes directly into the box with the 3 sockets where i plug the air purifier, a speaker and the PSU. Not sure how this works or if relevant for this whole thing.
Also, both sockets are flat, they aren't wired to earth.
Another note is that as you can see, on top of my computer I have the headphone amp, the silver box, and it's unplugged, because like I said before, it gives me the buzz when I touch the volume knob.
I can't also touch the laptop other than the keyboard because it's made out of metal.
Any tips etc? I would like to be able to use my laptop on my desk.
