    Hello Everyone,

    I have a late 2011 macbook pro 15 inch. I upgraded the ram to 8 gigs, and I have a samsung 840 ssd installed. I have noticed that I get roughly a 20% battery drain overnight when the computer is in sleep mode. Now the computer is set to sleep, not hibernate. I had read somewhere that doing this prevent the ram from being written to the hard drive, and thus increased the life of your ssd. My computer doesn't hibernate unless I close the lid when the battery is really low (configured that way).

    Is this powerless normal when the computer is just sleeping and not hibernating?

    Switch off all networking, remove the mouse and any network adapters
    and measure again.
