Putting the computer to sleep
Sleep is a power conservation feature of PowerBook computers, reducing the amount of power the computer draws when it’s not being used. When the PowerBook is in sleep, it has a darkened screen and appears to be off. If you have a PowerBook Duo 280c, a green light flashes on the top of the display case when your computer is in sleep.
To put the computer to sleep:
mChoose the Sleep command from the Special menu. (The computer must be on in order for you to put it to sleep.)
For information on other ways of putting the computer to 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.)
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.)
