Crackling sound... what is it? (not speakers)

    I've noticed lots of laptops make that noise. My Macbook never made that noise until recently (or maybe since it's so quiet I only notice it when I'm in a silent room). Anyway, does anyone know what it is? Is it the RAM, the hard drive, the graphics chip? Whenever there's some activity, like opening or closing an application, it'll crackle faintly.

    And, is that normal, or signs of early wear? If it's bad, I've only had it for like 2 weeks so it would suck if something was wrong. But like I said, I've heard it on other laptops.

    it's the hard drive "thinking" and it's completely normal. :p
