Chapter 12. Computing on the Move with P... > Managing Your Mobile Mac's Power

Managing Your Mobile Mac's Power

The factor that makes a mobile Mac mobile is the capability to run using battery power. This is obviously an advantage, but it also adds another task for you, which is managing that power so you maximize your battery life and thus your working time while on the move.

Using the Power Management Menu

When you run Mac OS X on a mobile Mac, by default you see the power management icon (see Figure 12.1). If you click this icon, the power management menu appears. At the top of this menu is an icon that keeps you informed about the power state of your Mac. When the battery is fully charged and you are running on the AC adapter, you see the plug icon. When the battery is charging, you see the lightning bolt icon and an estimate of either the time or the percent until the battery is fully charged. If you open the menu, you will see information about the state of the battery, such as whether it is charging, is fully charged, or how much running time it has; the Show command that you can use to change the displayed value; the current source of power for your mobile Mac (Power Adapter or Batter); power setting options from which you can choose; and the Open Energy Saver command to open the Energy Saver pane of the System Preferences application.
