netbook RF interference

I've got one of those little ASUS IEEE netbooks. It works fine for my purpose but since I use it to control my SSB (ICOM M710-RT) I noticed that when I plug it in either to AC or DC then my SSB starts picking up quite some noise (even in the case the netbook is not wired to the radio at all).

I even tried to power it with a DC plug using a totally separate battery bank but I keep picking up the same noise which is not there when I run it on its internall battery only.

It must be the AC transformer (when I charge it from AC) or the DC converter when I plug it into the lighter socket. When the power cord is not connected to the netbook the radio picks up no RF noise but I would think it stands to reason since neither transformer/converter have any load connected.
As soon as I plug it in into the netbook then there it is!

Any idea? Also the stereo is picking up some of the noise.
How can I try to reduce it?

Thanks
Scud
