Power off memory during standy
hibernatemode supports values of 0, 3, or 25. Whether or not a hiberna-
tion image gets written is also dependent on the values of standby and
autopoweroff

For example, on desktops that support standby a hibernation image will be
written after the specified standbydelay time. To disable hibernation
images completely, ensure hibernatemode standby and autopoweroff are all
set to 0.

hibernatemode = 0 by default on desktops. The system will not back memory
up to persistent storage. The system must wake from the contents of mem-
ory; the system will lose context on power loss. This is, historically,
plain old sleep.

hibernatemode = 3 by default on portables. The system will store a copy
of memory to persistent storage (the disk), and will power memory during
sleep. The system will wake from memory, unless a power loss forces it to
restore from hibernate image.

hibernatemode = 25 is only settable via pmset. The system will store a
copy of memory to persistent storage (the disk), and will remove power to
memory. The system will restore from disk image. If you want “hiberna-
tion” – slower sleeps, slower wakes, and better battery life, you should
use this setting.

It is suggested to power off memory at stand-by with the following command:
