    Why would the i7 choose to shutdown rather than hibernate or sleep?

    Smart sleep was set to 5% and it should have hibernated since the battery charge fell below 5%

    What causes the machine to choose to shutdown instead of hibernate or sleep?

    pmset -g

    I've also noticed this on my 15" i5. Not changed any of the power settings or anything like that.

    why don't you open a terminal window and post your pmset settings

    pmset -g

    I had sleep mode so I guess with a flat battery I can expect it to shutdown.

    Anyway, now i'm running version 2.6 of smartsleep and I've set it to hibernate only
    because I'm using an SSD.

    My i5 did the same...shut down instead of sleep. I had read that unlike the earlier models that keep a small amount of battery charge in "reserve" to keep things in memory (which allows it to sleep), the newer models actually write the data to the HD and then completely shut down. When you begin to charge the battery again, the data is accessed from the HD and the computer is back where it was before it shut down...does this make sense? :confused:
