[code] hibernatemode = 0 by default on desktops. The system will not back memory up to persistent storage. The system must wake from the contents of memory; 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 "hibernation" - slower sleeps, slower wakes, and better battery life, you should use this setting.

Con 0 non va in ibernazione.
