Using Your MacBook

Important:

If only one indicator light is on, very little charge is left. If no lights are

visible, the battery is completely drained and the computer will not start up unless the

power adapter is connected. Plug in the power adapter to let the battery recharge, or

replace the drained battery with a fully charged battery (see “Removing the Battery” on

If the battery icon in the Finder menu bar is set to show the percentage of charge,

sometimes the battery won’t show a full 100 percent charge when the power adapter

is attached. This is normal behavior; battery life is maximized if charging is not

continuously cycled on and off when the battery’s charge capacity is between 95 and

100 percent. When the battery level eventually drops below 95 percent, it will charge

all the way up to 100 percent.
