 Two-finger rotating lets you rotate photos, pages, and more.  Three-finger swiping lets you rapidly page through documents, move to the previous or next photo, and more. Running Your MacBook Air on Battery Power When the 45W MagSafe Power Adapter is not connected, your MacBook Air draws power from its built-in rechargeable battery. The length of time that you can run your MacBook Air varies, depending on the applications you use and the external devices connected to your MacBook Air. Turning off features such as AirPort Extreme or Bluetooth® wireless technology can help conserve battery charge. If the battery runs low while you are working, attach the power adapter that came with your MacBook Air and let the battery recharge. When the power adapter is connected, the battery recharges whether the computer is on, off, or in sleep. The battery recharges more quickly, however, when the computer is off or in sleep. You can determine whether the battery needs charging by looking at the indicator light on the MagSafe connector. If the light is glowing amber, the battery needs to be charged. If the light is glowing green, the battery is fully charged. 34 Chapter 2 Life with Your MacBook Air

When the 45W MagSafe Power Adapter is not connected, your MacBook Air draws
power from its built-in rechargeable battery. The length of time that you can run your
MacBook Air varies, depending on the applications you use and the external devices
connected to your MacBook Air. Turning off features such as AirPort Extreme or
Bluetooth
®
wireless technology can help conserve battery charge.
If the battery runs low while you are working, attach the power adapter that came with
your MacBook Air and let the battery recharge. When the power adapter is connected,
the battery recharges whether the computer is on, off, or in sleep. The battery
recharges more quickly, however, when the computer is off or in sleep.
You can determine whether the battery needs charging by looking at the indicator
light on the MagSafe connector. If the light is glowing amber, the battery needs to be
charged. If the light is glowing green, the battery is fully charged.
