First, just so I understand correctly, it sounds like all is fine with the laptop on batteries so the problem is with the external power-supply/adapter, right?

Dave blames the fact that it's a switching supply. Sounds logical.

This may be a little un-conventional but to avoid all that "off-line" battery charging, do you all think using an old fashioned linear power-supply (probably have to DIY it) would solve the problem? Or might better decoupling, isolation or grounding do it. IDK but seems there should be a solution other than having to use batteries.

Just a few ideas, I don't have the computer instruments going yet but that's the way I'm headed.

Cheers,
Rock
