I once saw a study of EM radiation given off by common household appliances, including computers. The astounding thing was, it was impossible to predict which item would give off a lot of radiation and which very little - you could have two computers that were more or less equivalent in size, and you'd have dramatically different EM emissions, due to a multitude of factors, shielding etc. Same for every category of appliance - and f.ex. they found that AC clock radios give off a huge amount of EM, and they recommended that people not sleep with their heads too close to the clock radio - but the radiation profile was different for different brands etc. So, I guess what I'm saying is that how much EM radiation is given off by your laptop depends uniquely upon your particular model. Anyhow, I believe there are some regulations on some emissions to prevent interference, and that is probably listed somewhere on your user manual or label on the computer. You may then check w/ the manual on your watch (if you still have it!), and see whether there is some kind of threshold, and if the laptop meets/exceeds it. I don't think there's any way of knowing without some concrete investigation of the items in question.
