Default Compaq laptop problem

I have an issue with my 'Compaq Evo N600c'. When I plug it in via AC adapter, once in a while I can hear my laptop emiting a high frequency sound, and its not coming from the speakers, but when I unplug from it from the AC, the sound completly stops.

This concerns me very much, I use this laptop for college and 3D animation. Please any help would be GREAT!

thank you!
