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:
• Ifyourcomputerdoesnothaveavoltageselectionswitch,donotconnectthe
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.
• Ifyourcomputerhasavoltageselectionswitch,donotconnectthecomputerto
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.
Do not bend or modify the plug. If the plug is damaged, contact the manufacturer to
obtain a replacement.
