Apple Macintosh PowerBook 145 - Manual (Page 33)

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
m attach other equipment to it
m replace its battery
m conserve power when you won’t be using it for several hours
To turn the PowerBook off
m If the computer is on, choose the Shut Down command from
the Special menu. (The
Macintosh Basics tour teaches how to
choose a menu command.)
m If the computer is in sleep, wake it by pressing any key on the
keyboard (except Caps Lock), and then choose Shut Down.
s
Important: 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.
