®
Limited Warranty. For more information, refer to
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
Center for further guidance. For a list of Service and Support phone
numbers, see Chapter 6, “Worldwide telephone list,” on page 51.
© Copyright Lenovo 2009 1
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

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.
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
2 Safety and Warranty Guide
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.
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.
Chapter 1. Important safety information 3
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.
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.
4 Safety and Warranty Guide
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.
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.
Chapter 1. Important safety information 5
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.
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.
6 Safety and Warranty Guide
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.
Heat and product ventilation
Computers, power adapters, and many accessories can generate heat when
turned on and when batteries are charging. Always follow these basic
precautions:
v Do not leave your computer, power adapter, or accessories in contact with
your lap or any part of your body for an extended period when the
products are functioning or when the battery is charging. Your computer,
power adapter, and many accessories produce some heat during normal
operation. Extended contact with the body could cause discomfort or,
potentially, a skin burn.
v Do not charge the battery or operate your computer, power adapter, or
accessories near flammable materials or in explosive environments.
v Ventilation slots, fans, and 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.
Inspect your desktop computer for dust accumulation at least once every three
months. Before inspecting your computer, turn off the power and unplug the
computer’s power cord from the electrical outlet; then remove any dust from
vents and perforations in the bezel. If you notice external dust accumulation,
then examine and remove dust from the inside of the computer including heat
sink inlet fins, power supply vents, and fans. Always turn off and unplug the
computer before opening the cover. If possible, avoid operating your computer
within two feet of high-traffic areas. If you must operate your computer in or
near a high-traffic area, inspect and, if necessary, clean your computer more
frequently.
For your safety and to maintain optimum computer performance, always
follow these basic precautions with your desktop computer:

work.
Be aware that accessing network resources can leave your computer vulnerable
to computer viruses, hackers, spyware, and other malicious activities that
might damage your computer, software, or data. It is your responsibility to
ensure that you have adequate protection in the form of firewalls, antivirus
software, and anti-spyware software and keep this software up to date.
Chapter 1. Important safety information 13
Cleaning and maintenance
Keep your computer and workspace clean. Shut down the computer and then
disconnect the power cord before cleaning the computer. Do not spray any
liquid detergent directly on the computer or use any detergent containing
flammable material to clean the computer. Spray the detergent on a soft cloth
and then wipe the computer surfaces.
Using headphones or earphones
If your computer has both a headphone connector and an audio line-out
connector, always use the headphone connector for headphones (also called a
headset) or earphones.
CAUTION:
Excessive sound pressure from earphones and headphones can cause hearing
loss. Adjustment of the equalizer to maximum increases the earphones and
headphones output voltage and therefore the sound pressure level.
Excessive use of headphones or earphones for a long period of time at high
volume can be dangerous if the output of the headphone or earphone
connectors do not comply with specifications of EN 50332-2. The headphone
output connector of your computer complies with EN 50332-2 Sub clause 7.
This specification limits the computer’s maximum wide band true RMS output
voltage to 150 mV. To help protect against hearing loss, ensure that the
headphones or earphones you use also comply with EN 50332-2 (Clause 7
Limits) for a wide band characteristic voltage of 75 mV. Using headphones that
do not comply with EN 50332-2 can be dangerous due to excessive sound
pressure levels.
If your Lenovo computer came with headphones or earphones in the package,
as a set, the combination of the headphones or earphones and the computer
already complies with the specifications of EN 50332-1. If different headphones
or earphones are used, ensure that they comply with EN 50332-1 (Clause 6.5
Limitation Values). Using headphones that do not comply with EN 50332-1 can
be dangerous due to excessive sound pressure levels.
Additional safety information
CAUTION:
Plastic bags can be dangerous. Keep plastic bags away from babies and
children to avoid danger of suffocation.

Chapter 2. Arranging your workspace
To get the most from your computer, arrange both the equipment you use and
your work area to suit your needs and the kind of work you do. Your comfort
is of foremost importance, but light sources, air circulation, and the location of
electrical outlets can also affect the way you arrange your workspace.
Comfort
Although no single working position is ideal for everyone, here are a few
guidelines to help you find a position that suits you best.
Sitting in the same position for a long time can cause fatigue. The backrest and
seat of your chair should adjust independently and provide good support. The
seat should have a curved front to relieve pressure on the thighs. Adjust the
seat so that your thighs are parallel to the floor and your feet are either flat on
the floor or on a footrest.
When using the keyboard, keep your forearms parallel to the floor and your
wrists in a comfortable position. Use a light touch on the keyboard and your
hands and fingers relaxed. Change the angle of the keyboard for maximum
comfort by adjusting the position of the keyboard feet.
Viewing Distance
Lower
Back
Support
Seat
Height
Adjust the monitor so the top of the screen is at, or slightly below, eye level.
Place the monitor at a comfortable viewing distance, usually 51 to 61 cm (20 to
24 inch), and position it so you can view it without having to twist your body.
Also, position other equipment you use regularly, such as the telephone or a
mouse, within easy reach.

Glare and lighting
Position the monitor to minimize glare and reflections from overhead lights,
windows, and other light sources. Reflected light from shiny surfaces can cause
annoying reflections on your monitor screen. Place the monitor at right angles
to windows and other light sources, when possible. Reduce overhead lighting,
if necessary, by turning off lights or using lower wattage bulbs. If you install
the monitor near a window, use curtains or blinds to block the sunlight. You
can adjust the brightness and contrast controls on the monitor as the room
lighting changes throughout the day.
Where it is impossible to avoid reflections or to adjust the lighting, an antiglare
filter placed over the screen might be helpful. However, these filters might
affect the clarity of the image on the screen; try them only after you have
exhausted other methods of reducing glare.
Dust buildup compounds problems associated with glare. Remember to clean
your monitor screen periodically using a soft cloth as directed in your monitor
documentation.
Air circulation
Your computer and monitor produce heat. The computer has a fan that pulls in
fresh air and forces out hot air. The monitor lets hot air escape through vents.
Blocking the air vents can cause overheating, which might result in a
malfunction or damage. Place the computer and monitor so that nothing blocks
the air vents; usually, 51 mm (2 inches) of air space is sufficient. Also, make
sure the vented air is not blowing on people.
Electrical outlets and cable lengths
The location of electrical outlets, the length of power cords and cables that
connect to the monitor, printer, and other devices might determine the final
placement of your computer.
When arranging your workspace:
v Avoid the use of extension cords. When possible, plug the computer power
cord directly into an electrical outlet.
v Keep power cords and cables neatly routed away from walkways and other
areas where they might get kicked accidentally.
For more information about power cords, see Chapter 1, “Important safety
information,” on page 1.
16 Safety and Warranty Guide
Chapter 3. Setting up your computer
Before you begin, make sure you set up your computer in the best possible
work area that suits your needs and the kind of work you do. For more
information, see Chapter 2, “Arranging your workspace,” on page 15 or go to:
http://www.lenovo.com/healthycomputing
Note: Be sure to read and understand Chapter 1, “Important safety
information,” on page 1 before you set up your computer. The precautions and
guidelines will help you work safely.
Installing the vertical stand
Depending on your computer model, a vertical stand can be used to place
your computer in the vertical position. If your computer comes with a vertical
stand, do the following to install the stand:
1. Position your computer in the vertical position.
2. Align the tab on the vertical stand with the notch on the computer as
shown.
3. Pivot the vertical stand towards the front of the computer until it snaps
into position.
4. Carefully position the computer upside down so that the computer sits on
the vertical stand.

Connecting your computer
Use the following information when connecting your computer.
v Look for the small connector icons on the back of your computer. Match the
connectors to the icons.
v If your computer cables and connector panel have color-coded connectors,
match the color of the cable end with the color of the connector. For
example, match a blue cable end with a blue connector or a red cable end
with a red connector.
Note: Depending on your model, your computer might not have all the
connectors that are described in this section.
1. Check the position of the voltage-selection switch on the rear of the
computer. Use a ballpoint pen to slide the switch, if necessary.
Note: Some computers do not have a voltage-selection switch. These
computers automatically adjust to the voltage at the electrical outlet
regardless of the country or region where the computer is being
connected.
v If the voltage supply range is 100–127 V AC, set the switch to 115 V.
v If the voltage supply range is 200–240 V AC, set the switch to 230 V.
