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.
In some extreme cases, choosing the wrong voltage range could potentially cause
explosion or fire.
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
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.
