Solving Problems

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.
Ensure that the power supply light on the

back of the system is on. If the light is off

there may be a possible problem with the

power supply or the power cable.

If the power light is solid white and the
computer is not responding
— The display may

not be connected or powered on. Ensure that

the display is properly connected and then turn

it off, then back on.

If the power light is blinking white — The

computer is in sleep state. Press a key on the

keyboard, move the pointer on the trackpad or a

connected mouse, or press the power button to

resume normal operation.
If you encounter interference that hinders
reception on your computer
— An unwanted

signal is creating interference by interrupting or

blocking other signals. Some possible causes of

interference are:

Power, keyboard, and mouse extension

cables.
Too many devices connected to a power

strip.
Multiple power strips connected to the same

electrical outlet.
