Power and the batteries

Your computer receives its power through the AC adapter and
power cable or from the system batteries (main battery and
optional secondary battery). Power problems are interrelated.
For example, a faulty AC adapter or 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 does not come on when you plug in
the AC adapter and power cable.
Make sure the AC adapter and power cable are firmly
plugged into both the wall outlet and the computer.
If the AC power light still does not come on, check that the
wall outlet is working properly by plugging in a lamp or other
appliance.
The AC adapter and power cable work correctly, but the
battery will not charge.
The battery doesn't charge while the computer is consuming
full power. Try turning off the computer.
The main battery may not be inserted correctly in the
computer. Turn off the computer, remove and replace the
battery.
The battery may be too hot or too cold to charge properly. If
you think this is the probable cause, let the battery reach
room temperature and try again.
