Important safety information
This information can help you safely use your 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.
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 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.

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.
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. For a list of Service and Support phone
numbers, go to the following Web site:
http://www.lenovo.com/support/phone
Frequently inspect your computer and its components for damage or 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.

User Guide

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.
• Power cords, plugs, power adapters, extension cords, surge protectors, or power supplies that are
cracked, broken, or damaged.
• Signs of overheating, smoke, sparks, or fire.
• Damage to a battery (such as cracks, dents, or creases), discharge from a battery, or a buildup of foreign

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 a 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.
CAUTION:

Before replacing any CRUs, turn off the computer and wait three to five minutes to let the computer
cool before opening the cover.

vii

Power cords and power adapters
DANGER
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.
Protect power cords 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.
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 pins 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.
To prevent possible overheating, do not cover the power adapter with clothing or other objects
when the power adapter is plugged into an electrical outlet.

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
DANGER
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.
Do not share an electrical outlet with other home or commercial appliances that draw large amounts
of electricity; otherwise, unstable voltage might damage your computer, data, or attached devices.
Some products are equipped with a three-pronged plug. This plug fits only into a grounded
electrical outlet. This is a safety feature. Do not defeat this safety feature by trying to insert it into
a non-grounded outlet. If you cannot insert the plug into the outlet, contact an electrician for an
approved outlet adapter or to replace the outlet with one that enables this safety feature. Never
viii

cable while the computer power is on; otherwise, you might damage your computer. To avoid possible
damage to attached devices, wait at least five seconds after the computer is shut down to disconnect
external devices.

General battery notice
DANGER
Personal computers manufactured by Lenovo contain a coin cell battery to provide power to
the system clock. In addition, many mobile products, such as notebook computers, utilize a
rechargeable battery pack to provide system power when in portable mode. Batteries supplied by
Lenovo for use with your product have been tested for compatibility and should only be replaced
with approved parts.
Never attempt to open or service any battery. Do not crush, puncture, or incinerate batteries or
short circuit the metal contacts. Do not expose the battery to water or other liquids. Only recharge
the battery pack strictly according to instructions included in the product documentation.
Battery abuse or mishandling can cause the battery to overheat, which can cause gasses or flame
to “vent” from the battery pack or coin cell. If your battery is damaged, or if you notice any
discharge from your battery or the buildup of foreign materials on the battery leads, stop using the
battery and obtain a replacement from the battery manufacturer.

Batteries can degrade when they are left unused for long periods of time. For some rechargeable
batteries (particularly Lithium Ion batteries), leaving a battery unused in a discharged state could
increase the risk of a battery short circuit, which could shorten the life of the battery and also can
pose a safety hazard. Do not let rechargeable Lithium-Ion batteries completely discharge or store
these batteries in a discharged state.

Rechargeable battery notice
DANGER
Do not attempt to disassemble or modify the battery pack. Attempting to do so can cause an
explosion, or liquid leakage from the battery pack. A battery pack other than the one specified by
Lenovo, or a disassembled or modified battery pack is not covered by the warranty.
If the rechargeable battery pack is incorrectly replaced, there is danger of an explosion. The battery
pack contains a small amount of harmful substances. To avoid possible injury:
• Replace only with a battery of the type recommended by Lenovo.
• Keep the battery pack away from fire.
• Do not expose it to water or rain.
• Do not attempt to disassemble it.
• Do not short-circuit it.
• Keep it away from children.
• Do not drop the battery pack.
Do not put the battery pack in trash that is disposed of in landfills. When disposing of the battery,
comply with local ordinances or regulations.
The battery pack should be stored at room temperature, charged to approximately 30 to 50%
of capacity. We recommend that battery pack be charged about once per year to prevent
overdischarge.

Lithium coin cell battery notice
DANGER
Danger of explosion if battery is incorrectly replaced.
When replacing the lithium coin cell battery, use only the same or an equivalent type that is
recommended by the manufacturer. The battery contains lithium and can explode if not properly
used, handled, or disposed of.
Do not:
• Throw or immerse into water
• Heat to more than 100°C (212°F)
• Repair or disassemble
Dispose of the battery as required by local ordinances or regulations.

Usage environment and your health
Integrated wireless cards emit radio frequency electromagnetic energy like other radio devices. However, the
level of energy emitted is far much less than the electromagnetic energy emitted by wireless devices like
for example mobile phones.
Due to the fact that integrated wireless cards operate within the guidelines found in radio frequency safety
standards and recommendations, Lenovo believes they are safe for use by consumers. These standards and
recommendations reflect the consensus of the scientific community and result from deliberations of panels
and committees of scientists who continually review and interpret the extensive research literature.
In some situation or environment, the use of integrated wireless cards may be restricted by the proprietor
of the building or responsible representatives of the organization. These situations and areas may for
example include:
• Using the integrated wireless cards on board of airplanes, in hospitals or near petrol stations, blasting
areas (with electro-explosive devices), medical implants or body-worn electronic medical devices, such
as pace makers.
• In any other environment where the risk of interference to other devices or services is perceived or
identified as harmful.
If you are uncertain of the policy that applies to the use of wireless devices in a specific organization (such as
airport or hospital), you are encouraged to ask for authorization to use integrated wireless cards prior to
turning on the computer.
