My experience is very dated, but I bought a used windows Asus laptop in 2013 and put Ubuntu on it and experienced no problems. I had been using Linux for a long time, so maybe I remember this with rose glasses, but it was very straight forward. Also an integrated GPU, but of the 2013 era. I think the laptop was a 2012 model.
Config isn’t hard, it just takes time 🙂
I don’t think I am the target audience for these products, and have no answers for you, but am curious what these would do above what turning the device off. Is a device that is powered off still reachable? Or is this not about that?
Anyway, on to the non answers, when i worked around wiring that needed to not be affected by interference from adjacent wiring, it would we shielded by aluminum. It was thicker than household foil, and had braiding. The wires could be run with other, non shielded wires, most of which were dramatically different voltages.
I am not a scientist 😅
