laptops are hard to shield.
better keep maximum distance.
you can use a mouse and an external keyboard and shield the whole thing except for the screen, e.g. in aluminium foil or fine stainless steel gauze.
there are also panels that can be placed in front of screens and that may help, like :

https://www.norad4u.com/emf-exposure-reduction/using-pcs-and-laptops/the MOST important thing is to ground the laptop in case the charger is ungrounded, or only use it on the battery.
otherwise very strong and in some cases even enormous electrical fields will emit from the laptop.
you can plug an usb extension cable into the machine and ground the outer part of the plug at the other end of the cable.
this is the most easy option that will do the trick.
you can also replace the charger ( same voltage, no less power ) by one that is fed with a 3-prong cable.
the socket in which the electricity plug goes should of course be grounded as well.
