Safety and warranty guide

Note

Please read important safety information ﬁrst.

This information can help you safely use your desktop or notebook personal

computer. Follow and retain all information included with your computer. The

information in this document does not alter the terms of your purchase agreement

or the Lenovo™ Limited Warranty. For more information, refer to “Lenovo Limited

Warranty.”

Customer safety is important. Our products are developed to be safe and effective.

However, personal computers are electronic devices. Power cords, power

adapters, and other features can create potential safety risks that can result in

physical injury or property damage, especially if misused. To reduce these risks,

follow the instructions included with your product, observe all warnings on the

product and in the operating instructions, and review the information included in

this document carefully. By carefully following the information contained in this

document and provided with your product, you can help protect yourself from

hazards and create a safer computer work environment.

Note: This information includes references to power adapters and batteries. In

addition to notebook computers, some products (such as speakers and monitors)

ship with external power adapters. If you have such a product, this information

applies to your product. In addition, computer products contain a coin-sized

internal battery that provides power to the system clock even when the computer

is unplugged, so the battery safety information applies to all computer products.

Conditions that require immediate action

Products can become damaged due to misuse or neglect. Some product

damage is serious enough that the product should not be used again until it

has been inspected and, if necessary, repaired by an authorized servicer.

Important safety information

Chapter

2Safety and warranty guide

As with any electronic device, pay close attention to the product when it is

turned on. On very rare occasions, you might notice an odor or see a puff

of smoke or sparks vent from your product. Or you might hear sounds like

popping, cracking, or hissing. These conditions might merely mean that an

internal electronic component has failed in a safe and controlled manner. Or,

they might indicate a potential safety issue. However, do not take risks or

attempt to diagnose the situation yourself. Contact the Customer Support

Center for further guidance.

Frequently inspect your computer and its components for damage, wear,

or signs of danger. If you have any question about the condition of a

component, do not use the product. Contact the Customer Support Center

or the product manufacturer for instructions on how to inspect the product

and have it repaired, if necessary.

In the unlikely event that you notice any of the following conditions, or if you

have any safety concerns with your product, stop using the product and

unplug it from the power source and telecommunication lines until you can

speak to the Customer Support Center for further guidance.

Note: If you notice these conditions with a product (such as an extension cord)

that is not manufactured for or by Lenovo, stop using that product until you can

contact the product manufacturer for further instructions, or until you get a suitable

replacement.

Safety and warranty guide

General safety guidelines

Always observe the following precautions to reduce the risk of injury and property

damage.

Service and upgrades

Do not attempt to service a product yourself unless instructed to do so by the

Customer Support Center or your documentation. Only use a service provider who

is approved to repair your particular product.

Note: Some computer parts can be upgraded or replaced by the customer.

Upgrades typically are referred to as options. Replacement parts approved

for customer installation are referred to as Customer Replaceable Units, or

CRUs. Lenovo provides documentation with instructions when it is appropriate

for customers to install options or replace CRUs. You must closely follow all

instructions when installing or replacing parts. The Off state of a power indicator

does not necessarily mean that voltage levels inside a product are zero. Before you

remove the covers from a product equipped with an ac power cord, always make

sure that the power is turned off and that the product is unplugged from any power

source. If you have any questions or concerns, contact the Customer Support

Center.

Although there are no moving parts in your computer after the power cord has

been disconnected, the following warnings are required for your safety.

Caution

Hazardous moving parts. Keep ﬁngers and other body parts away.

Attention

Before replacing any CRUs, turn off the computer and wait three to ﬁve

minutes to let the computer cool before opening the cover.

4Safety and warranty guide

Static electricity prevention

Static electricity, although harmless to you, can seriously damage computer

components and options. Improper handling of static-sensitive parts can cause

damage to the part. When you unpack an option or CRU, do not open the static-

protective package containing the part until the instructions direct you to install it.

When you handle options or CRUs, or perform any work inside the computer, take

the following precautions to avoid static-electricity damage:

• Limityourmovement.Movementcancausestaticelectricitytobuilduparound

you.

• Alwayshandlecomponentscarefully.Handleadapters,memorymodules,and

other circuit boards by the edges. Never touch exposed circuitry.

• Preventothersfromtouchingcomponents.

• Whenyouinstallastatic-sensitiveoptionorCRU,touchthestatic-protective

package containing the part to a metal expansion-slot cover or other unpainted

metal surface on the computer for at least two seconds. This reduces static

electricity in the package and your body.

• Whenpossible,removethestatic-sensitivepartfromthestatic-protective

packaging and install the part without setting it down. When this is not possible,

place the static-protective packaging on a smooth, level surface and place the

part on it.

• Donotplacethepartonthecomputercoverorothermetalsurface.

Power cords and power adapters

Use only the power cords and power adapters supplied by the product

manufacturer.

The power cords shall be safety approved. For Germany, it shall be H05VV-F,

3G, 0.75 mm2, or better. For other countries, the suitable types shall be used

accordingly.

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.

Safety and warranty guide

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.
