I just noticed this last night but, whenever my powerbook is plugged into it's P-P-P-POWERBRICK, I hear a very faint buzzing sound. It immediately stops once it's running on battery power. Is this thing going bad? Is this a known issue? If this thing is dying I think I'm going to need someone to kick in the teeth.
 
It's all the electrons running from the wall into your PowerBook. I wouldn't worry about it too much. Have you just noticed it or has it suddenly got worse?
 
What happens if you take out the battery (while it's plugged in, obviously) ?

When I take it out, I still hear it.

Also, and I remember a thread on this a while back, it just started sounding like a lightsaber when I move it.
 
My 17" PowerBook has been buzzing ever since I got it back in August of 2005. It only does it with the AC Adapter plugged in. I think its access noise coming through the speakers. Its not a big deal to me and my PowerBook works fine and has been ever since I got it. So I wouldn't worry about the noise.
 
My 15" makes a bit of a high pitched buzz when the cpu performance is set to high in the preferences. Check that, perhaps its going to a lower performance setting when its on batteries. I would plug it in and try change the setting to see if you still hear it.

Of course I could be refering to a totally different sound all together but its worth a try.
