Charge the battery
The battery in your MacBook Air recharges whenever the MacBook Air is connected to power.
Charge the battery. Connect your MacBook Air to a power outlet using the included cable
and 45W MagSafe 2 Power Adapter. The indicator light glows amber to indicate the battery is
charging. The battery recharges more quickly when the computer is o or in sleep.
Check the battery’s charge. Look at the battery status icon at the right of the menu bar to see
the battery level or charging status. Click the icon to show how much power you have left if you
keep using the apps, peripheral devices, and system settings you’re now using.

Conserve battery power. To extend battery life on a given charge, you can reduce the display
brightness, close apps, and disconnect peripheral devices you’re not using. You can change your
power settings in Energy Saver preferences (click the System Preferences icon in the Dock,
then click Energy Saver). If your MacBook Air is in sleep when a device is connected to it, the
device’s battery may drain.
