Chapter 1. Important safety information
Note: Be sure to read and understand the 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
Chapter 3, “Lenovo Limited Warranty,” on page 19.
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) are shipped 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 Service
Provider.
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
© Copyright Lenovo 2009 1
Center for further guidance. For a list of Service and Support phone
numbers, see Chapter 4, “Worldwide Lenovo Support telephone list,” on
page 29.
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.
v Power cords, plugs, power adapters, extension cords, surge protectors, or
power supplies that are cracked, broken, or damaged.
v Signs of overheating, smoke, sparks, or fire.
v Damage to a battery (such as cracks, dents, or creases), discharge from a
battery, or a buildup of foreign substances on the battery.
v A cracking, hissing, or popping sound, or strong odor that comes from the
product.
v Signs that liquid has been spilled or an object has fallen onto the computer
product, the power cord, or power adapter.
v The computer product, power cord, or power adapter has been exposed to
water.
v The product has been dropped or damaged in any way.
v The product does not operate normally when you follow the operating
instructions.
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.
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.
2 Safety and Warranty Guide
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. For more information on CRUs, refer to the
ThinkCentre User Guide for this product. 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.
DANGER
Hazardous moving parts. Keep fingers and other body parts away.
CAUTION:
Before replacing any CRUs, turn off the computer and wait three to five
minutes to let the computer cool before opening the cover.
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:
v Limit your movement. Movement can cause static electricity to build up
around you.
Chapter 1. Important safety information 3
v Always handle components carefully. Handle adapters, memory modules,
and other circuit boards by the edges. Never touch exposed circuitry.
v Prevent others from touching components.
v 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.
v 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.
v 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 mm
2
, 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 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.
4 Safety and Warranty Guide
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 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:
v 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.
v 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.
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.
Chapter 1. Important safety information 5
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.
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 overall system load should not exceed 80
percent of the branch circuit rating. Consult an electrician for more information
if you have questions about power loads and branch circuit ratings.
Be sure that the power outlet you are using is properly wired, easily accessible,
and located close to the equipment. Do not fully extend power cords in a way
that will stress the cords.
Be sure that the power outlet provides the correct voltage and current for the
product you are installing.
Carefully connect and disconnect the equipment from the electrical outlet.
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.
Batteries
All personal computers manufactured by Lenovo contain a non-rechargeable
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.
