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.
