Reseat the AC adapter 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.
Ensure that the electrical outlet is working •
by testing it with another device, such as
a lamp.
