    Anyone else notice a very soft clicking/whirring sound when the machine wakes from sleeping? It sounds like a harddrive head being moved.

    However, I was under the impression the drives were all solid state. I personally cannot imagine any moving parts in there..

    Any ideas where this is coming from?

    You sure? To be clear, its not happening 98% of the time the machine is on.

    Only happens when starting up from wake (and maybe from cold boot --not sure on that one though).

    I guess, since it didn't sound like a fan, I excluded it as a possibility....

    So yeah, now I'm thinking it's probably that.
