Important safety information
This information can help you safely use your IBM
®
personal computer.
Follow and retain all information included with your IBM computer. The
information in this document does not alter the terms of your purchase
agreement or the IBM Statement of Limited Warranty.
Customer safety is important to IBM. 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 mobile personal computers, IBM 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 IBM Support Center or the
© Copyright IBM Corp. 2004 iii

product manufacturer for instructions on how to inspect the product and
have it repaired, if necessary. The telephone numbers for your IBM Support
Center location are located in the Telephone numbers section of this guide.
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 IBM 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, 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, the 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 non-IBM product (such as an
extension cord), 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
Do not attempt to service a product yourself unless instructed to do so by the
IBM Support Center. Use only an IBM authorized service 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. IBM 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
iv ThinkPad

G40 Series Service and Troubleshooting Guide

source before you attempt the replacement. If you have any questions or
concerns, contact the IBM Support Center.
Power cords and power adapters
Use only the power cords and power adapters supplied by the product
manufacturer.
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.
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.
Important safety information v

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.
Connect and disconnect the equipment from the electrical outlet carefully
Batteries
Many IBM personal computers contain a non-rechargeable coin cell battery to
provide power to the system clock. In addition many mobile products such as
Thinkpad notebook PCs utilize a rechargeable battery pack to provide system
power when in portable mode. Batteries supplied by IBM for use with your
product have been tested for compatibility and should only be replaced with
IBM 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 not leave the base of your computer in contact with your lap or any
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 not operate your computer or charge the battery near flammable
materials or in explosive environments.
v 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.
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
v Do not bend or flex CD/DVD discs, or force them into the computer or
their packaging
v Check CD/DVD discs for cracks before each use. Do not use cracked or
damaged discs

Information about hard disk capacity
Instead of providing a recovery CD or a Windows
®
CD with your computer,
IBM provides simpler methods of accomplishing the tasks typically associated
with these CDs. The files and programs for these alternative methods are on
your hard disk, which eliminates having to locate misplaced CDs and
problems associated with using an incorrect CD version.
The complete backup of all the files and programs that IBM preinstalled on
your computer resides in a hidden section, or partition, of the hard disk.
Although hidden, the backups in the partition consume hard disk space.
Therefore, when checking the capacity of your hard disk according to
Windows you might note that the total capacity of the disk appears to be
smaller than anticipated. This discrepancy is explained by the contents of the
hidden partition. (See “Recovering pre-installed software” on page 32.)
For more information about recovering your hard disk to the original
preinstalled contents refer to your on-system help source, Access IBM. Press
the blue Access IBM button or click the Access IBM icon on your desktop, and
then browse the Learn section for various topics that cover backing up and
recovering.
