    Hi, I'm very curious.

    According from this guide:
    http://guides.macrumors.com/Your_Mac_and_Sleep_Mode

    There are 3 diff. sleep modes. I know the normal one. But I don't quite get about the other 2.
    Is 'Save sleep mode' still powers your RAM? and if it does.
    Is Suspend mode dissemble the power from he RAM?
    And wouldn't it be more energy sufficient if we use suspend mode?
    What's the pros and cons between these 2 modes?

    Safe Sleep mode uses slightly more power than Suspend mode, but it is negligible. The benefit of Safe Sleep mode over Suspend mode is that the RAM is still powered and still has data. With Suspend mode, on the other hand, the system must transfer the data from the hard drive to the RAM before starting up, which will take a little extra time.

    In summary, battery life is marginally better with Suspend Mode, but start up times are faster with Safe Sleep.

    Incidentally, if all power is lost during Safe Sleep mode, the computer reverts to Suspend mode.
