8.12. Energy Saver

The Energy Saver program helps you and your Mac in a number of ways. By blackening the screen after a period of inactivity, it prolongs the life of your monitor. By putting the Mac to sleep half an hour after you've stopped using it, Energy Saver cuts down on electricity costs and pollution. On a laptop, Energy Saver extends the length of the battery charge by controlling the activity of the hard drive and screen.

Figure 8-8. Top: Here's what Energy Saver looks like in its expanded condition on a laptop. (On a desktop machine, it's far simpler.) If you turn on the "Put the display to sleep" option, you can specify an independent sleep time for the screen.

Bottom: Here's the relevant slice of the Schedule tab—a welcome return of the Mac's self-scheduling abilities.
