Charging the Battery
When the power adapter that came with your MacBook Pro is connected, the battery
charges whether the computer is on, off, or in sleep. The battery charges more quickly,
however, if the computer is off or in sleep.
The battery in your MacBook Pro can be replaced only by an Apple Authorized Service
Provider or an Apple Retail Store.
