Power and the batteries
Your computer receives its power through the AC adapter and
power cable or from the system batteries (main battery, real-time
clock (RTC) battery and backup battery). Power problems are
interrelated. For example, a faulty power cable will neither power
the computer nor recharge the batteries.
Here are some typical problems and how to solve them:
The AC power light doesn’t come on when you plug in the
AC adapter.
Make sure the AC adapter is firmly plugged into both the power
cable and the computer, and that the power cable is plugged into
the wall outlet.
If the AC power light still doesn’t come on, check that the wall
outlet is working properly by plugging in a lamp or other
appliance.
The power cable and AC adapter work correctly, but the
battery won’t charge.
The main battery may not be making a good electrical connection.
Turn off the computer, remove the battery and confirm that its
contacts are clean. If they are dirty, clean the contacts with a soft,
dry cloth and replace the battery.
The battery may be too hot or too cold to charge properly. Its
temperature needs to be in the range 50°-88° F (10°-30 °C). If you
think this is the probable cause, let the battery reach room
temperature and try again.
If the battery has completely discharged, it will not begin charging
immediately. Leave the AC adapter connected, wait 20 minutes
and see whether the battery is charging.
If the battery icon is glowing after 20 minutes, let the computer
continue charging the battery for at least another 20 minutes
before you turn on the computer.
