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.
Check the AC adapter cable connections.

If the AC adapter has a light, ensure that the
