This sounds relatively simple to test. Get a laptop, write a script to randomly enable/disable wi-fi every $timeinterval (and log whether or not it was enabled). (Also need to block the taskbar icon, somehow... can probably just hide it.) If 10 minutes of Wi-Fi being on is enough to cause noticeable symptoms, it should be quite easy to prove that - if you can successfully determine whether or not Wi-Fi is on, better than chance, you have one heck of a significant result! You could save lots of people, most likely, from nasty symptoms And if not... well, you have options there too. (Of course, you have to make sure you get enough trials- and fix it ahead of time, can't just stop when you see a significant result!)

For myself, it's the electronics in the base of a laptop that bothers me most that I must shield from - and I use a wireless keyboard to keep my hands off of the keyboard of the laptop, otherwise my hands start to hurt very quickly. I don't appear to be sensitive enough to sense interference or sensitivity to wi-fi etc, or it's too subtle compared to stronger electrical pollution, so I just can't perceive it.

  That sounds far more ergonomic than electromagnetic or possibly temperature sensitivity. If that was the case then the wireless keyboard should be even worse. I found at times switching to a non flat keyboard helped when they were starting to bother me.

    No, this isn't an ergonomic issue - though yes, my shoulders are relaxed with the keyboard on my lap. Also, wifi would be far less of a strength of EMF than whatever is being emitted from the laptop base - so I'm not sure how you came to the conclusion that wifi would be worse. Edit: For anyone wondering how I know this, I can rest my hands where I have my laptop, however if I have the EMF shield/cover over the base, then my hands don't start to hurt when resting them.

What are the typical radiated power levels from a modern laptop over 20kHz-5.8GHz, excluding Wi-fi and other radios? Does anyone have any references to share, such as E/H spectrums of a typical modern laptop, which has gone through EM compliance testing?

  I was able to find one stumbling around google, if anyone else is interested. Lenovo X1 G3 from Sporton[1]. And a less comprehensive report from Intek, for 2016 random brand convertible [2].
