Power and the battery
The computer battery may not be accessible by the user.
Your computer receives its power through the AC adaptor
and power cord/cable or from the system battery. Power
problems are interrelated. For example, a faulty AC adaptor
or power cord/cable will neither power the computer nor
recharge the battery.
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.
