Important safety information
Note
Please read important safety information first.
This information can help you safely use your ThinkCentre
® or ThinkPad ®
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
™ Statement of 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 asafer computer work environment.
Note: This information includes references to power adapters and batteries. In
addition to mobile personal 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, your
computer product may contain acoin-sized internal battery that provides
power to your system clock even when the machine is unplugged, so the
battery safety information applies to all computers.
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 apuff of
smoke or sparks vent from your machine. Or you might hear sounds like
popping, cracking or hissing. These conditions might merely mean that an
internal electronic component has failed in asafe and controlled manner. Or,
they might indicate apotential safety issue. However, do not take risks or
attempt to diagnose the situation yourself.
Frequently inspect your computer and its components for damage or wear or
signs of danger. If you have any question about the condition of acomponent,
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 conditions listed below, or if
you have any safety concerns with your product, stop using the product and
©Copyright IBM Corp. 2006 v

unplug it from the power source and telecommunication lines until you can
speak to the Customer Support Center for further guidance. See “Information
resources” on page xiii.
vPower cords, plugs, power adapters, extension cords, surge protectors, or power
supplies that are cracked, broken or damaged.
vSigns of overheating, smoke, sparks or fire.
vDamage to abattery (such as cracks, dents, creases), discharge from abattery, or
abuildup of foreign substances on the battery.
vAcracking, hissing or popping sound, or strong odor that comes from the
product.
vSigns that liquid has been spilled or an object has fallen onto the computer
product, the power cord or power adapter.
vThe computer product, the power cord or power adapter has been exposed to
water.
vThe product has been dropped or damaged in any way.
vThe product does not operate normally when you follow the operating
instructions.
Note: If you notice these conditions with aproduct (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 asuitable replacement.
General safety guidelines
Always observe the following precautions to reduce the risk of injury and property
damage.
Service
Do not attempt to service aproduct yourself unless instructed to do so by the
Customer Support Center. Use only aservice provider who is approved to repair
your particular product.
Note: Some parts can be upgraded or replaced by the customer. These parts are
referred to as Customer Replaceable Units, or CRUs. Lenovo expressly
identifies CRUs as such, and provides documentation with instructions
when it is appropriate for customers to replace those parts. You must closely
follow all instructions when performing such replacements. Always make
sure that the power is turned off and that the product is unplugged from
any power source before you attempt the replacement. 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 proper UL certification.
vi User Guide

Danger
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.
Power cords and power adapters
Use only the power cords and power adapters supplied by the product
manufacturer.
Never wrap apower cord around the 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 asafety hazard.
Always route power cords so that they will not be walked on, tripped over, or
pinched by objects.
Protect the cord and power adapters from liquids. For instance, do not leave your
cord or power adapter near sinks, tubs, toilets, or on floors that are cleaned with
liquid cleansers. Liquids can cause ashort circuit, particularly if the cord or power
adapter has been stressed by misuse. Liquids can also cause gradual corrosion of
the power cord terminals and/or the connector terminals on the 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 and/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
Important safety information vii

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 areceptacle (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 aqualified electrician.
Do not bend or modify the plug. If the plug is damaged, contact the manufacturer
to obtain areplacement.
Some products are equipped with athree-pronged plug. This plug fits only into a
grounded electrical outlet. This is asafety feature. Do not defeat this safety feature
by trying to insert it into anon-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 away that
will stress the cords.
Carefully connect and disconnect the equipment from the electrical outlet.
Batteries
All personal computers manufactured by Lenovo contain anon-rechargeable coin
cell battery to provide power to the system clock. In addition many mobile
products such as ThinkPad notebook PCs utilize arechargeable 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 abattery unused
in adischarged state could increase the risk of abattery short circuit, which could
shorten the life of the battery and can also pose asafety hazard. Do not let
rechargeable Lithium-Ion batteries completely discharge or store these batteries in a
discharged state.
