you guys are not alone. We did some testing on the laptop and found this to be a ground loop in what appers to be the laptop power supply. The only way to get rid of this is to lift the earth ground by using a 3 plug to 2 adapter.
BEWARE BEWARE BEWARE!!!! WHEN YOU DO THIS YOU MUST PLUG EVERYTHING IN THE SAME POWER STRIP. DO NOT PLUG THE COMPUTER IN ONE PLUG IN THE WALL AND THE REST OF YOUR EQUIPMENT IN ANOTHER.
ALSO MAKE SURE YOU DO NOT LIFT ANY OTHER GROUND. I AM NOT TELLING YOU TO DO THIS. DO THIS AT YOUR OWN RISK. AS OF RIGHT NOW THIS IS THE ONLY WAY TO GET RID OF THE NOISE.
THIS NOISE HAS NOTHING TO DO WITH YOUR DISC OR HOSTER ITS COMMING FROM THE LAPTOP IF YOU WANT TO CHECK THIS UNPLUG THE LAPTOP FROM THE WALL AND USE JUST THE BATTERY. THE NOISE WILL GO AWAY.
HAVE A GOOD ONE MIKE.
