dell 5150 power brick

[d franko]

I've been having this problem where I end up with this nasty noise in my audio, mainly from my internal sound card on both of my computers. I've narrowed it down to only being a problem when my laptop is connected to the power supply. The effect is lessened when it's put on a different circuit, but not completely fixed. Anyone else have this same problem or know if it would be solved by using a power conditioner of some sorts? Thank you.
