Putting Your MacBook Air to Sleep or Shutting It Down
When you finish working with your MacBook Air, you can put it to sleep or shut it
down.
Putting Your MacBook Air to Sleep
If you’ll be away from your MacBook Air for only a short time, put it to sleep. When the
computer is in sleep, you can quickly wake it and bypass the startup process.
To put your MacBook Air to sleep, do one of the following:
Â
Close the display.
 Choose Apple () > Sleep from the menu bar.
 Press the power (®) button and click Sleep in the dialog that appears.
 Choose Apple () > System Preferences, click Energy Saver, and set a sleep timer.
To wake your MacBook Air:
 If the display is closed, simply open it to wake your MacBook Air.
 If the display is already open, press the power (®) button or any key on the keyboard.
When your MacBook Air wakes from sleep, your applications, documents, and
computer settings are exactly as you left them.
NOTICE: If your MacBook Air has a hard drive, wait a few seconds until the sleep
indicator light on the front of your MacBook Air starts pulsing (indicating that the
computer is in sleep and the hard disk has stopped spinning) before you move your
MacBook Air. Moving your computer while the hard disk is spinning can damage it,
causing loss of data or the inability to start up from the hard disk.
