Turning the PowerBook on and off
Your Macintosh PowerBook can be in one of three power states:
off, sleep, or on.

Off

When the PowerBook is off, the computer is not using any power
or doing any work. The terms shut down and off both refer to this
state.
You should turn the computer off to
mattach other equipment to it
mreplace its battery
mconserve power when you won’t be using it for several hours

To turn the PowerBook off

mIf the computer is on, choose the Shut Down command from
the Special menu. (The Macintosh Basics tour teaches how to
choose a menu command.)
mIf the computer is in sleep, wake it by pressing any key on the
keyboard (except Caps Lock), and then choose Shut Down.
SImportant: Don’t shut down with the power button on
the back panel of the computer unless a problem prevents
you from choosing Shut Down. You will lose any work you
did not save, and you may experience problems with your
hard disk. S
