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
http://support.lenovo.com.
Frequently inspect your computer and its components for damages 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.

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.
Note: Some computer parts can be upgraded or replaced by the customer.
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.
Before replacing any CRUs, turn off the computer and wait three to five
minutes to let the computer cool before opening the cover.
■ Power cords and power adapters
Use only the power cords and power adapters supplied by the product
manufacturer. The power cord and power adapter are intended for use with
this product only. They should never be used with any other product.
The power cords shall be safety approved. For
2
3G, 0.75 mm
, 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 str
ess the cord in ways that can cause the cord to fray, crack, or crimp.
This can present a safety hazard.
Always route power cords or any other cables
on, tripped over, or pinched by objects.

Chapter 1. Important safety information
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.
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.
■ 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
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.

Chapter 1. Important safety information
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 overload an electrical outlet. The

■ Power supply statement
Never remove the cover on a power supply or any part that has the
following label attached.
Hazardous voltage, current, and energy levels are present inside any
component that has this label attached. There are no serviceable parts inside
these components. If you suspect a problem with one of these parts, contact a
service technician.
■ External devices
Do not connect or disconnect any external device cables other than USB and
1394 cables 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.

Chapter 1. Important safety information
■ Batteries
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 can also pose a safety
hazard. Do not let rechargeable Lithium-Ion batteries completely discharge
or store these batteries in a discharged state.
■ Rechargeable battery notice
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.
6
Chapter 1. Important safety information
• 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.
If the battery pack is to be stored separately, place it in a dry environment
of a temperature between 10-35 °C and keep it away from direct sunlight.
To extend battery life, we recommend you charge the battery to
approximately 30 to 50% capacity and recharge it every three months to
prevent the battery from over-discharging.
This system does not support batteries that are not genuine Lenovo-made
or authorized. The system will continue to boot, but may not charge
unauthorized batteries.
■ Lithium coin cell battery notice
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.
The following statement applies to users in the state of California, U.S.A.

Chapter 1. Important safety information
■ Heat and product ventilation
Computers, AC adapters, and many accessories can generate heat when
turned on and when batteries are charging. Notebook computers can
generate a significant amount of heat due to their compact size. Always
follow these basic precautions:
• When your computer is turned on or the battery is charging, the base, the
palm rest, and some other parts may become hot. Avoid keeping your
hands, your lap, or any other part of your body in contact with a hot
section of the computer for any extended length of time. When you use the
keyboard, avoid keeping your palms on the palm rest for a prolonged
period of time. Your computer generates some heat during normal
operation. The amount of heat depends on the amount of system activity
and the battery charge level. Extended contact with your body, even
through clothing, could cause discomfort or even a skin burn. Periodically
take breaks from using the keyboard by lifting your hands from the palm
rest; and be careful not to use the keyboard for any extended length of
time.
• Do not operate your computer or charge the battery near flammable
materials or in explosive environments.
• Ventilation slots, fans and/or heat sinks are provided with the product for
safety, comfort, and reliable operation. These features might inadvertently
become blocked by placing the product on a bed, sofa, carpet, or other
flexible surface. Never block, cover, or disable these features.
• When the AC adapter is connected to an electrical outlet and your
computer, it generates heat. Do not place the adapter in contact with any
part of your body while using it. Never use the AC adapter to warm your
body. Extended contact with your body, even through clothing, may cause
a skin burn.
For your safety, always follow these basic precautions with your computer:
• Keep the cover closed whenever the computer is plugged in.
• Regularly inspect the outside of the computer for dust accumulation.
• Remove dust from vents and any perforations in the bezel. More frequent
cleanings might be required for computers in dusty or high-traffic areas.
• Do not restrict or block any ventilation openings.
• Do not operate your computer inside furniture, as this might increase the
risk of overheating.
• Airflow temperatures into the computer should not exceed 35°C (95°F).
