    i was using this to test out some basic html:

    when i listened closely, when i type in that box, especially in between the "put the body..." tags, i notice there is a type of squeaking sound with each keystroke i make (coming from inside the computer).

    does this happen to anyone else?

    My older 800 MHz titanium PowerBook is pretty quiet, but my PowerBook 2400c used to make all kinds of "squeaky" sounds, as does my G5 PowerMac, and to a lesser extent my old 400 MHz G4 PowerMac. I believe it's some kind of interference between the CPU and GPU, as I notice it most when dropping down menus with the mouse, and scrolling (mouse movement affecting onscreen UI items seems to be a primary trigger for the noise). Anyway, I think a lot of computers (especially Macs) suffer from this phenomenon, and AFAIK there's nothing you can do about it.

    I have a 17" PowerBook and I notice this issue sometimes when typing on the computer... I thought I was hearing things, but if someone else hears some squeaking noises too, maybe I'm not alone. :p
