Power Problems
If the power light is off — The computer is either turned off or is not receiving power.
•Reseat the power cable into both the power connector on the computer and the electrical outlet.
•If the computer is plugged into a power strip, ensure that the power strip is plugged into an electrical outlet and that the power strip is turned on. Also bypass power protection devices, power strips, and power extension cables to verify that the computer turns on properly.
