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:
v 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.
v 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
Ensure that extension cords, surge protectors, uninterruptible power supplies,
and power strips that you use are rated to handle the electrical requirements of
the product. Never overload these devices. If power strips are used, the load
should not exceed the power strip input rating. Consult an electrician for more
information if you have questions about power loads, power requirements, and
input ratings.
Plugs and outlets
If a receptacle (power outlet) that you intend to use with your computer
equipment appears to be damaged or corroded, do not use the outlet until it is
replaced by a qualified electrician.
