Solving Problems
Network Problems
If the network connection is lost —
• Check the cable to ensure it is plugged in
and not damaged.
• Check the status of the link integrity light (top
left light on the network connector).
The link integrity light on the integrated network
connector lets you verify that your connection is
working and provides information on the status:
• Yellow light — A good connection exists
between a 10/100-Mbps network and the
computer.
• Off (no light) — The computer is not
detecting a physical connection to the
network. For assistance, contact your
network administrator or ISP.
Power Problems
If the power light is off — The computer is
either in hibernate mode, turned off, or is not
receiving power.
• Press the power button to resume normal
operation.
• 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.
