Grounding Issue with Laptop AC adapter

[witzendoz]

I know how "I" fix laptop earth loops (personal use only) but it would be irresponsible of me to post it on a public forum.

Probably the same way I do it LOL.

The only other ways to do it is as I said earlier, usb isolator or audio isolators between the apogee and everything else (I have used audio isolators when recording live location stuff to the laptop and it has fixed ground problems). Also think about trying an aftermarket isolated power supply that won't have a mains earth due to the double insulation.
