Register your computer with Lenovo

To register your computer, go to http://www.lenovo.com/register. Then, follow the instructions on the screen
to complete the registration. This can help authorities return your computer to you if it is lost or stolen.
Registering your computer also enables Lenovo to notify you about possible technical information and
upgrades.
When you register your computer, information is entered into a database, which enables Lenovo to contact
you in case of a recall or other severe problem. In addition, some locations offer extended privileges and
services to registered users.

Moving your computer to another country or region

When you move your computer to another country or region, you must take local electrical standards into
consideration. This section provides information on the following:
• "Voltage-selection switch" on page 23
• "Replacement power cords" on page 23

Voltage-selection switch

Some computers are equipped with a voltage-selection switch located near the power-cord connection
point on the computer and some computers do not have a voltage-selection switch. Before you install
your computer or relocate your computer to another country or region, you must be certain that you have
matched your computer to the voltage available at your electrical outlet.
CAUTION:
You must know the voltage of the electrical connection (outlet) where your computer will be
connected. If you do not know the voltage, 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.
If your computer has a voltage-selection switch, you must set the switch to match the voltage available at
your electrical outlet. Setting the voltage-selection switch incorrectly will cause the computer to malfunction
and might cause permanent damage to the computer. Do not connect the computer to an electrical
outlet until you have verified that the voltage-selection switch setting matches the voltage available at the
electrical outlets.
If your computer does not have a voltage-selection switch, inspect the voltage-rating label on the bottom of
the computer and note the following:
• If the voltage-rating label shows a range of either "100-127 V" or "200-240 V," you must ensure that the
voltage provided at the electrical outlet matches the voltage rating on the computer label. If it does
not match, do not attempt to connect the computer to the electrical outlet, unless an external device
such as a voltage-converting transformer is used.
• If the voltage-rating label shows a dual range of "100-127 V" and "200-240 V," this signifies that the
computer is suitable for worldwide operation and the computer will automatically adjust to the voltage at
the electrical outlet regardless of the country or region where the computer is being connected.

Replacement power cords

If you relocate your computer to a country or region that uses an electrical outlet style different from the
type you are currently using, you will have to purchase either electrical plug adapters or new power cords.
You can order power cords directly from Lenovo.
