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
