    Very strange questions I know but...

    1) What colour is the Powor LED on the front of the Mini?

    2) When in Standby should it Pulse or does it just stay off?

    Thanks in Advance :)

    Mini Mac 2012 LED

    On my 2012 Mini Mac the front LED is pulsing when it is entering in Sleep Mode/Standby but after like 1h30 or 2h00 the LED is going off as if the computer was shut down, which is not the case because it wakes up immediately with Share screen... This is a little bit strange.

    I have not find any answer about that.

    After 4 hours, the sleeping Mac Mini will shutdown into hibernate mode (writes memory to disk). This is a new behaviour.

    Try terminal command: pmset -g

    Thanks for the comment.
    So basically by looking at it you have no idea if you Mac Mini is shut down or in hibernate mode ? For me it is about 2 hours before the Led is going off. Can you control the time after which it is going into hibernate mode ?
    I do not see any difference in term of time by waking up the Mini Mac from sleeping mode or hibernate mode.

    No pulsing LED in hibernate mode will be bring some confusion...

    The pulsing LED is how it used to be: RAM has power, processor sleeps.

    LED off: processor sleeps, RAM is written to disk and has no power too. In this case, the wake-up takes marginally longer.

    You can control this behaviour with the pmset command.

    Check man page: man pmset

    Thanks again for your time.
    Did you manage to completely remove the hibernate mode ? It means that your led is pulsing in sleep mode but never going off unless you shut down your mini mac ?
    When the computer change from sleep mode to hibernate mode what is exactly going on ? I have the impression my Time machine is running during at this moment....
    All very strange this new feature...

    Yes, everything you can configure: immediate hibernate, or sleep only. If you have a wake-up time configured, it will not hibernate at all, just sleep.

    Actually I like the new mode, delayed hibernate after some time.
