Saving Energy

When you're not using your computer, you can save energy by putting it to sleep. When you put your computer to sleep, the power mode is set to low and the screen goes black to save energy. Your computer is still running, so it takes less time for it to wake up. You can use the Sleep command on the Apple menu to put your computer right to sleep, or you can put your computer and display to sleep automatically when it has been idle for a specific amount of time or when you schedule it at a regular time interval. You can also set the hard disk to sleep whenever possible to save more energy. If you have an iBook or PowerBook, it automatically goes to sleep when you close the lid. You move your mouse or press a key to wake it up. If a security option is set in the Security pane in System Preferences, your computer requires a password when it wakes from a sleep. You can also schedule a computer restart or shutdown, at a regular time interval, or a restart after a power failure.

Set Sleep Options

Click the System Preferences icon in the Dock, and then click the Energy Saver icon.

Click the Sleep tab, and then click Details, if necessary.

Drag the slider to set a time interval before sleep mode starts.

IMPORTANT To prevent your computer from sleeping, drag to Never to turn off sleep mode, and then clear the Put The Display To Sleep When The Computer Is Inactive For check box.

Select or clear the Put The Display To Sleep When The Computer Is Inactive For check box. If so, drag the slider to set a time interval.

TROUBLE? If the sleep time is less than the screen saver time, then increase the sleep time or click Screen Saver to change it's time.

To conserve energy, select the Put The Hard Disk(s) To Sleep When Possible check box.

Click the Close button.
