Solving Problems
Wired Connections
If the network connection is lost — The cable
is loose or damaged.
Check the cable to ensure it is plugged in •
and not damaged.
The link integrity light on the integrated network
connector lets you verify that your connection is
working and provides information on the status:
Green — A good connection exists between •
a 10-Mbps network and the computer.
Orange — A good connection exists between
•
a 100-Mbps network and the computer.
Off — The computer is not detecting a
•
physical connection to the network.
NOTE: The link integrity light on the network
connector is only for the wired cable
connection. The link integrity light does not
provide status for wireless connections.
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.
