Power and the batteries
Your computer receives its power through the AC adapter and
power cord/cable or from the system batteries (battery,
optional high-capacity battery and real-time clock (RTC)
battery). Power problems are interrelated. For example, a
faulty AC adapter or power cord/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 cord/cable.
Make sure the AC adapter and power cord/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 cord/cable work correctly,
but the battery will not charge.
The battery does not charge while the computer is consuming
full power. Try turning off the computer.
The battery may not be inserted correctly in the computer.
Turn off the computer, remove the battery, clean the contacts
with a soft dry cloth (if necessary) and replace the battery.
See
“Removing the battery from the computer” on page 118
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.
If the battery has completely discharged, it will not begin
charging immediately. Leave the AC adapter and power cord/
cable connected, wait 20 minutes and see if the battery is
charging.
If the battery light is glowing after 20 minutes, let the
computer continue charging the battery for at least another 20
minutes before you turn on the computer.
