Laptop Static When Plugged In

[aldernon]

My laptop makes an annoying static noise when it is plugged in to the power cord. If i remove the power cord, the static noise goes away.

I noticed this in my old desktop when i ran off the built in sound. I added a sound card and the static disappeared.

It's just gotta be some kind of interference im thinking.

Im just curious if there's anything i can really do to fix this problem. Aside from buying an external sound card setup for the laptop, does anyone have any solutions for this problem?

Thanks

Random static or AC "hum"? You might try an AC Line Interference Filter.
