Automatic sleep
If you don’t use the computer for several minutes, it goes to sleep
automatically. This conserves battery power.
To wake the computer, press any key on the keyboard (except Caps Lock).
The screen will reappear as it was before the computer went to sleep.
You can control the automatic sleep feature. For more information on sleep
and automatic sleep, see the “Batteries & Power” topic of Macintosh Guide,
available in the Guide (h) menu. (You can learn about using Macintosh
Guide in Chapter 2 of this manual.)
Restarting a computer that’s already on

software file, or start up the computer using a different disk.

screen (indicating a temporary software problem). In this case, use the
trackpad to click the Restart button that appears.
Follow these instructions to restart your computer:
1 Press and hold the Power key for about two seconds.
2 Click the Restart button.
