@user1096901 see the manual page for pmset for the details on which timers transition into hibernation and or deep sleep.

If the screen is dark but the LED is lit and steady then only the display is sleeping. If the LED is fading between off and on (with a rate similar to that of a human breathing), then it is sleeping or hibernating. If the screen is dark and the LED is not lit, the machine is off. | |
