I then spent the full 100 bucks for a dc 
dc converter for my laptop  and still got hash.  I wrapped that converter up 
in tin foil and a  copper braid to ground and the NB took it out.

I've used a DC-DC car adapter for my laptop in my HF mobile operations, and  
it is dead quiet. For convenience I always have run it from a separate 20  AH 
battery.
 
A friend tried a DC-DC converter and had a lot of noise while running  it 
from the car's electrical system.  He then went the separate battery  route, and 
the noise disappeared. 
 
The separate battery trick still does not cure the AC-DC inverter  noise.  
But for the computer, you might give it a try.
