I will be interested in the answer to this. I've noticed the same thing playing movies and the noises peg with CPU usage. When I removed the power supply the noise goes away.

Subject: [PCBUILD] Noisy Laptop Power Supply

A friend of mine just purchased a new HP laptop for the express purpose of 
playing music at square dances. We discovered that the power supply is 
generating noise when he tries to play the music and also when he tries to 
copy music from his record collection (old 45's). What can be done other 
than running the laptop from its batteries (which won't last long enough for 
and evening's music)? There is no ferrite bead on the power supply lead. 
Would that help? Any other ideas?
