Power and the Batteries

Your computer receives its power through the AC adapter or from
the system batteries (main battery, real-time clock (RTC) battery
and backup battery). Power problems are interrelated. For exam-
ple, a faulty AC adapter will neither power the computer nor
recharge the batteries.
Here are some typical problems and how to solve them:
The power light doesn't come on when you plug in the AC
adapter.
Make sure the AC adapter is firmly plugged into both the wall out-
let and the computer.
If the power light still does not come on, check that the wall outlet
is working properly by plugging in an electrical device such as a
lamp.
The AC adapter works correctly, but the battery won't charge.
The main battery may not be inserted correctly in the computer.
Turn off the computer, remove the battery, clean the battery con-
tacts with a soft cloth dipped in alcohol and replace the battery.
The battery may be too hot or too cold to charge properly. Its tem-
perature needs to be in the range of 50°-88°F (10°-30°C). If you
think this is the probable cause, let the battery reach room temper-
ature 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.
