Laptop causes my 817 to have a noise level of S8 when on

Hello

I am running a Fujitsu Laptop connecting to my Signalink and 817 to run WSPR

When I turn on my laptop my noise level on my 817, be it 20m, 40m or 80m is S8. If I turn off my Laptop those bands are about S1 - S2, even if the power supply is still connected. So all good.

Even pulling out the power supply and running on batteries it is still S8. If I take my laptop to the other side of the room the noise is still S8.

I can only stop this noise by turning OFF my laptop. As you can imagine, this is rather frustrating if I want to use WSPR.
Maybe I need a new laptop or maybe a tablet?

Any advice will be greatly welcomed.....
