High pitched noise when scrolling

Interesting problem here. Whenever I scroll, either with the scroll bar or using the scroll feature on the touchpad, there seems to be a high pitched noise coming from my screen. I haven't been able to pin-point it, but anytime that screen scrolls, I can hear it.

Anyone else encountering this? By the way, I'm using a 15" hires Powerbook.

15" hi-res PB, 1.67GHz, 1.5G RAM, 80G, DL, Mac OS X (10.4.4), no more lines

Yes, I have also noticed it, but have figured out that it is normal. When I am plugged into the power adapter and using the trackpad, I hear the sound. When I am using the battery, there is no sound and it is fine. It seems normal to me because it isn't random and only happens when you input a command (moving your fingers over the trackpad). I am not too worried, but after a while it is kind of annoying to me.
