Power and the batteries
Your computer receives its power through the AC adaptor and
power cord/cable or from the system batteries (battery and real-time
clock (RTC) battery). Power problems are interrelated. For
example, a faulty AC adaptor 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 adaptor and power cord/cable.
Make sure the AC adaptor 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 adaptor 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 system may be too hot or too cold to charge properly. If you
think this is the probable cause, let the system reach room
temperature and try again.
