Important:
If only one flashing 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 page 54).
If the battery icon in the Finder menu bar is set to show the percentage of charge, you
might sometimes notice that the battery does not attain a full 100 percent charge
when the power adapter is attached. This is normal behavior; battery life is saved when
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 to 100 percent.
