Voltage-Selection Switch; Extension Cords And Related Devices - Lenovo K100 Warranty Manual

Never wrap a power cord around a power adapter or other object. Doing so can stress the cord in ways that
can cause the cord to fray, crack, or crimp. This can present a safety hazard.
Always route power cords so that they will not be walked on, tripped over, or pinched by objects.
Protect power cord and power adapters from liquids. For instance, do not leave your power cord or power
adapter near sinks, tubs, toilets, or on floors that are cleaned with liquid cleansers. Liquids can cause a short
circuit, particularly if the 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

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.
