Customer safety is important to Lenovo. 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

Note: This informationincludesreferencestopoweradaptersandbatteries.In
addition to mobile personal computers, Lenovo ships some products (such as
speakers or monitors) with external power adapters. If you have such a
product, this information applies to your product. In addition, your computer
product may contain a coin-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 a puff 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 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.
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. For a list of Service and Support phone
numbers, see “Worldwide telephone list” on page 63.
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 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,poweradapters,extensioncords,surgeprotectors,or

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
Do not attempt to service a product yourself unless instructed to do so by the
Customer Support Center. Use only a service provider who is approved to
repair your particular product.

R51e Series Service and Troubleshooting Guide
Note: Some partscanbeupgradedorreplacedbythecustomer.Theseparts
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.
Danger
Hazardous moving parts. Keep fingers and other body parts away.
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.
Never wrap a power 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 a safety 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 a short 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.
Important safety information vii
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 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.
Batteries
viii ThinkPad
Do not bend or modify the plug. If the plug is damaged, contact the
manufacturer to obtain a replacement.
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.
Carefully connect and disconnect the equipment from the electrical outlet.
All personal computers manufactured by Lenovo contain a non-rechargeable
coin cell battery to provide power to the system clock. In addition many
®
R51e Series Service and Troubleshooting Guide
mobile products such as ThinkPad notebook PCs 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.
Heat and product ventilation
Computers generate heat when turned on and when batteries are charging.
Notebook PCs can generate a significant amount of heat due to their compact
size. Always follow these basic precautions:
v Do notleavethebaseofyourcomputerincontactwithyourlaporany
part of your body for an extended period when the computer is functioning
or when the battery is charging. Your computer produces some heat during
normal operation. Extended contact with the body could cause discomfort
or, potentially, a skin burn.
v Do notoperateyourcomputerorchargethebatterynearflammable
materials or in explosive environments.
v Ventilation slots,fansand/orheatsinksareprovidedwiththeproductfor
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.

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, you should also examine and remove dust from the inside of
the computer including heat sink inlet fins, power supply vents, and fans.
Important safety information ix
Always turn off and unplug the computer before opening the cover. If
possible, avoid operating your computer within 2 feet of high-traffic areas. If
you must operate your computer in or near a high-traffic area, you should
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:
v Keep the cover closed whenever the computer is plugged in.
v Regularly inspect the outside of the computer for dust accumulation.
v Remove dust from vents and any perforations in the bezel. More frequent
cleanings might be required for computers in dusty or high-traffic areas.
v Do not block or restrict airflow into the front of the computer.
v Do not block the airflow vents on the back of the computer.
v Do not store or operate your computer inside furniture, as this might
increase the risk of overheating.
v Airflow temperatures into the computer should not exceed 35° C (95° F).
v Do not use non-ThinkCentre air filtration devices.
CD and DVD drive safety
CD and DVD drives spin discs at a high speed. If a CD or DVD is cracked or
otherwise physically damaged, it is possible for the disc to break apart or
even shatter when the CD drive is in use. To protect against possible injury
due to this situation, and to reduce the risk of damage to your machine, do
the following:
v Always store CD/DVD discs in their original packaging
v Always store CD/DVD discs out of direct sunlight and away from direct
heat sources
v Remove CD/DVD discs from the computer when not in use
