Apple Macintosh LC 575 - Manual (Page 30)

Saving energy
Your Macintosh comes with software that reduces the amount of
energy consumed when you are not using your computer. The
software allows you to set the screen to turn off after a period of
inactivity, the length of which you specify. The image on the
screen reappears when you move the mouse or press any letter or
number key on the keyboard. Because the screen needs to warm
up, it will take up to 15 seconds for the picture to reappear.
Turning off the screen conserves energy. It also protects the
screen from “burning in” images, which can occur if you leave an
unchanging image on the screen for many hours or days.
S
Important: When the screen is off, the computer is still on.
The green light on the front of the computer indicates that
the computer is still on.

To set the screen to turn off:
1. Choose Control Panels from the Apple (
K) menu.
2. Open the Screen control panel.
3. Click the box labeled “Turn off built-in screen when
idle.”
4. Drag the slider to choose the number of minutes until
the screen turns off.
For example, if you choose 15 minutes, your screen will
darken after your computer has been inactive for 15 minutes.
The image will appear once again, exactly as you left it, if you
move the mouse or press any letter or number on the
keyboard.
Because the screen needs to warm up, it will take up to 15
seconds for the picture to reappear. During this warmup
period, you will hear a beep.
