power cord or power adapter has been stressed by misuse. Liquids also can
cause gradual corrosion of power cord terminals and/or the connector terminals
on a power adapter, which can eventually result in overheating.
Always connect power cords and signal cables in the correct order and ensure that
all power cord connectors are securely and completely plugged into receptacles.
Do not use any power adapter that shows corrosion at the ac input pins or shows
signs of overheating (such as deformed plastic) at the ac input or anywhere on the
power adapter.
Do not use any power cords where the electrical contacts on either end show
signs of corrosion or overheating or where the power cord appears to have been
damaged in any way.

Voltage-selection switch

Some computers are equipped with a voltage-selection switch located near the
power-cord connection point on the computer. If your computer has a voltage-
selection switch, ensure that you set the switch to match the voltage available at
your electrical outlet. Setting the voltage-selection switch incorrectly can cause
permanent damage to the computer.
If your computer does not have a voltage-selection switch, your computer is
designed to operate only at the voltage provided in the country or region where the
computer was originally purchased.
If you relocate your computer to another country, be aware of the following:
• If your computer does not have a voltage-selection switch, do not connect the
computer to an electrical outlet until you have verified that the voltage provided
is the same as it was in the country or region where the computer was originally
purchased.
• If your computer has a voltage selection switch, do not connect the computer
to an electrical outlet until you have verified that the voltage-selection switch is
set to match the voltage provided in that country or region.
If you are not sure of the voltage provided at your electrical outlet, contact your
local electric company or refer to official Web sites or other literature for travelers to
the country or region where you are located.

Extension cords and related devices
