About "Sleep" and "Deep Sleep"

"Sleep" and "deep sleep" are used to refer to low-power modes of the computer.

This article has been archived and is no longer updated by Apple.

When you select the Sleep command in Mac OS (or when the computer goes to sleep as a result of Energy Saver settings), as many components as possible will enter a low-power mode.

If all hardware components and connected peripherals are in a low-power mode, your computer is in "deep sleep". However, not all hardware components and peripherals are capable of running in a low-power mode.

If one or more hardware components or peripherals does not enter a low-power mode, your computer may simply sleep.
