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.
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
light on the AC adapter is on.
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 and then back on.
If the power light is blinking white — The
computer is in standby mode. Press a key on
the keyboard, move the pointer using the touch
pad 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.
