Power and the batteries
Your computer receives its power through the AC adapter and 
power cable or from the system batteries (main battery, real-time 
clock (RTC) battery and backup battery). Power problems are 
interrelated. For example, a faulty 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 doesn’t come on when you plug in the 
AC adapter.
Make sure the AC adapter is firmly connected to both the power 
cable and the computer, and that the power cable is plugged into 
the electrical outlet.
If the AC power light still doesn’t come on, check that the 
electrical outlet is working properly by plugging in a lamp or other 
appliance.
