I've sometimes noticed something similar on my PowerBook G4 when working 
on the battery only and few times right after the power supply has been 
attached.

And as you say - 4 clicks/sounds or whatever one should call it... To me 
it sounds like a very low 'sssh-sssh'. I think it may be a sort of a 
relay that is switching on and off. I've located the sound to come 
somewhere between the inner end of the battery and the back end of the 
DVD drive.

Cheers, Erik Richard
