    No, Power Nap only works on 2011 MacBook Airs and the MacBook Pro Retina.

    If your computer came with a solid state memory system, then, yes, you should be able to use it. If you have a HD, then, no, the option is not available. See the Mountain Lion features page about Power Nap - http://www.apple.com/osx/whats-new/features.html#powernap - and note the footnote.

     

    I can't use it either as I have a third-party SSD.

    "If your computer came with a solid state memory system, then, yes, you should be able to use it. "

     

    That is not true, my MacBook Pro came with an SSD from Apple.

     

    Only the 2011 Macbook Airs and the MacBook Pro Retina have Power Nap. As I already stated.

    Don't mind me, should have been paying less attention to the Olympics and Rangers game and more to my answers.

     

    Thanks for the valuable assist.

     

    And I never mind you.

    Congrats on the win, are you going to try to top our 2 out of 3 against Bobby V?

     

    There will be a test after the March so pay attention.

    It's not just an SSD (which is basically a Hard Drive that uses solid state circuitry instead of optical or magnetic media - it still connects via SATA, which requires a separate power connection) that makes PowerNap work on the New Airs and Pros, it's the fact that the New Airs and Retina Pros use Flash Memory, which is technically the same type of storage that iPads and iPhones use...  it is connected directly to the motherboard.  It does not depend on a SATA connection, and also does not require a separate power connection - if the computer is on (even in sleep mode), the memory is on.  This is what makes PowerNap possible.

    No, they don't use the same Flash Memory as the iPads and iPhones. They use SSDs with newer controllers on the chipset. It is the controller combined with the SSD that makes Power Nap possible.

    The inside of a Retina MacBook Pro:

    The flash memory module from a MacBook Air:

    Note the lack of resemblence of either flash memory module to a typical SATA Solid State Disk:

    Your first two pictures are of the RAM modules, not the SSD storage. There is no 768 GB Flash Storage.
