Whats the better low EMF setup? Laptop or Computer?

@Purp1eOne I agree .
It's very hard to predict.
Currently i use a Chromebook. I ordered one right before that but it had such a high EMF reading on my meter that I had to return it. It also gave me symptoms IIRC. Then I bought my current Chromebook and it had like 10 times less EMF radiation for whatever reason... they're the same size.So I ordered a new Lenovo laptop today since I read that EMF sensitive people often do well with newer models of Lenovo. But if the EMF values are too high I'll simply return it and get another one.
Experimentation ...
Dare to think.

@Purp1eOne Have you tried those?
Does it make sense to use them if you never use your laptop on your lap ? Im not sure- It seems to shield the radiation going downwards into the ground.
But Im using my laptop on a desk so im more concerned about the radiation that comes towards me and I dont see how this is helping there. Maybe Im missing something.Dare to think.

I have purchased two new laptops.
1. Lenovo Laptop | 17,3" | Intel 8505 | 5 x 4.40 GHz
Radiation: 1-6 uT, mostly between 1.5-2.5 uT2. HP 17,3" Full-HD IPS Notebook AMD Ryzen 3 5300U @3,8GHz
Radiation: 0,2-1,5 uT, mostly between 0,2-0.7 uTSo you can see the Lenovo one emits at least 3-4 times more radiation, for no obvious reason.
I will return the first one.Radidation seems to vary a lot from model to model. Only one way to find out: to buy it.
Acutally its surprising that I could not find a comprehensive list of laptop models and their radiation levels anywhere on the internet. So im posting this here to help others.The HP one is still higher than my chromebook, but it is a lot larger and has more power.
With my chromebook I had a similar situation, I bought two and the first one had a radiation several times higher than my current one- Go figure... -

Mauritio you can keep this thing and use it as a kind of mobile thin client, to remote control anything that's more powerful. RDP's very good these days, clever codecs. As the antennas in the lid, your orientation to it and its orientation to a router would have something to do with the additional traffic negating a benefit.
This is what I do a lot of the time, with a crappy tablet, a "netbook" or any other low power device in reach. I can't really get away from EMF.
-
@Mauritio I have not tried that shield. From the little research I have done it seems hard to avoid EMF without avoiding the devices. Looked at grounding but that can actually make you more attractive to the EMF.
What you are doing by looking at the radiation from each device is probably the best you can do at this point.
-
@Purp1eOne but do you think this device would help if you use the laptop on a desk? I don't see how, but maybe im missing something...
Dare to think.
-
@ThinPicking you mean use the chromebook as a remote of some sort ? That's a good idea. Or maybe I'll just get a simple, wireless keyboard (they're pretty low EMF) and use it with my laptop.
What's RDP?
Dare to think.

Exactly that. But your other idea seems fine too. Anything to put some distance between the I/O and the (most performant) compute will do really.
I don't have an EMF meter (yet) but I'm sure my serious equipment would be disgustingly noisy if I measured it. I don't like to be anywhere near it.

What's RDP?
Just one widely available screen and input remoting protocol. Used to be Microsoft specific but now very widely available. Commonly called xrdp in Linux.
-
@Mauritio again that depends on the device since the EMF patterns are not equal in all directions. You would have to take your meter and see if its sensitive enough to determine where the strongest signal is emanating from.
-
@Purp1eOne thanks for the suggestions. i measured below the laptop and i got values of up to 100uT !!! So i think some action is warranted on my side. Ill check if they ship to europe as well. and see if that thing helps.
I checked below my chromebook as well and the radiation doesnt go over 1uT. Insane difference.
-
I returned both of the above laptops and settled for a 16" Lenovo Chromebook.
It has higher EMF readings than my 14" Lenovo Chromebook, but it's stil ok .Next step is to buy a e ink tablet and a protection device for the laptop .
-
Does anybody know if these shielding devices actually work?
I read that they might also reflect the EMF back upwards which is bad as well.https://defendershield.com/defenderpad-laptop-radiation-heat-shield?ref=emfa

@Mauritio
Your laptop's external power supply will be one of the main EMF offenders.
Whenever possible, try to use a (third party) power supply with 3 wires going into it (phase, neutral, GROUND).
The ground takes away a lot of the EMF which would otherwise be emitted from the power supply and also passed on to the laptop.
You could try an interim solution or workaround by placing the power supply in a grounded metal cage.
Or placing a grounded mat underneath your laptop or underneath your desk where you usually place your laptop. With the latter, though, make sure to ground electronics surrounding your desk as well because those EMFs could be channelled into the same ground (for oversimplified illustration, imagine the grounding mat as a lightning rod for the environmental EMFs around you. I wouldn't be great to sit in between).
You can also buy or solder up a shielded (one-sided ground) USB cable to plug into your laptop and connect the USB-ground=Laptop-ground with a ground connector to plug into a wall socket at the other end.I'd expect that you'll notice huge differences in measuring the EMFs of your laptops plugged-in or running purely on internal battery power.

Use a desktop and attach about 6' extension adapter cables to your mouse, keyboard and monitor. Keep away from the tower itself. Although as Maurito pointed out, and I can confirm this with my own meter measuring, Laptops will generally emit more radiation. The towers are pretty well insulted and I suspect it is the metal encasing. Laptops have more plastic and not to mention we are generally closer to them. But with about 6 to 10 feet distance from a tower, you should be good.
-
Desktop is preferable because the laptop has a cord that has an inline transformer that puts out an electrical field.
