Using Your Power Adapter Plugging in the power adapter provides AC power to the MacBook Pro and recharges the computer's battery. Important: For optimal performance, use only the power adapter that came with your computer, or purchase an additional 85W Apple Portable Power Adapter. When you first connect your power adapter to your computer, an indicator light on the power adapter plug turns on. If you don't see a light, your plug is probably not seated correctly. Check for any debris and remove it, if necessary. An amber light indicates that power is going to the battery. A green light indicates that no power is going to the battery, which can mean the battery is fully charged, is not installed, or has a problem. You can monitor the battery level using the Battery status menu in the menu bar or by checking the battery level indicator lights on the bottom of the battery (see page 77). Warning: The MacBook Pro power adapter port contains a magnet that can erase data on a credit card, iPod, or other device. To preserve your data, keep these and other magnetic media away from the power adapter port. To extend the reach of your power adapter, first pull the AC plug up to remove it from the adapter. Attach the included AC power cord to the adapter, making sure it is seated firmly. Plug the other end into a power outlet. The AC power cord provides a grounded connection. 30 Chapter 2 Getting to Know Your MacBook Pro
