    Hy

    I recently noted that when I activated PowerNap on battery, it would (after a small amount of time 5 min -> 1 hour -> a day, at random), disable itself (at least, the checkmark for it would be unchecked).

    Does anyone know a "fix" or reason for that?

    Also, when I unmount my HDD, but leave it plugged in into my rMBP, close the lid, so my rMBP would sleep, it would (when using PowerNap on AC power) "wake" (to do stuff like checking e-mail etc), it also mounts my HDD and backs up to it, but then, when PowerNap has done it's thing, it would go back to sleep, but it won't unmount my HDD and it would when I wake it up, give the following error message:

    (does anyone knows of a program that will unmount all HDD's when the sleep command is triggered? even in PowerNap?)

    Well just eject the drive by moving it to the trash. The trash can will turn in to a eject icon.


    There is no way that I know of to eject drives at sleep or see a need.


    also power nap only works while pluged in

    there probably is a program for that, somewhere,
    I'm gonna search for it later.

    ps: no, you can use it on battery power:
