Description
Mac OS X Lion was designed to save time with its Mission Control view, iOS-like Launchpad and ability to run several apps at full screen. Apple put a lot of thought into how the hardware and software work together to maximize user productivity and minimize extra work. With these battery-saving tips, you won’t have to worry as much about your Mac running out of juice when you need it most.
1. Turn Off Bluetooth and Wi-Fi.
Disabling your notebook’s wireless radios is one surefire way to eke out more juice. While turning off Wi-Fi may not be practical in every situation—especially if you need to access the Internet often—it will give you more endurance if you’re using your laptop to watch a movie on an airplane.
To turn Bluetooth off:
Click the Bluetooth icon in the upper right-hand corner of the desktop.
Select Turn Bluetooth Off. The icon should now be grayed out.
Alternatively:
Select System Preferences > Bluetooth.
Uncheck the box marked On.
To turn Wi-Fi off:
Click on the Wi-Fi icon in the upper right-hand corner of the desktop.
Select Turn Wi-Fi Off. The icon should change from a number of concentric arcs to an outline that looks like a baseball diamond.
Alternatively:
Open System Preferences > Network.
Uncheck the box marked Turn Wi-Fi Off.
