Important safety information

Note

Please read 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

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.

™

Statement of Limited Warranty.

Note: This information includes references to power adapters and batteries. In

addition to notebook 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 contains 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 contact the Customer Support Center.

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.

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

© Lenovo 2006. Portions © IBM Corp. 2005. v

speak to the Customer Support Center for further guidance. See “Information
resources” on page xiii for more information.

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.

If you notice these conditions with a product (such as an extension cord)

Note:

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

Do not attempt to service a product yourself unless instructed to do so by the
Customer Support Center or your documentation. Use only a 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. 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.

The power cords shall be safety approved. For Germany, it shall be H05VV-F, 3G,

0.75 mm2, or better. For other countries, the suitable types shall be used
accordingly.

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.

Important safety information vii

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.

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.

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.

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.

viii User Guide

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 notebook 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.

Note: An optional floor stand should be used when placing your computer in the

vertical position.

Tools required

To install some options in your computer, you might need a flat-blade or Phillips
screwdriver. Additional tools might be needed for certain options. See the
instructions that come with the option.

Handling static-sensitive devices

Static electricity, although harmless to you, can seriously damage computer
components and options.

When you add an option, do not open the static-protective package containing the
option until you are instructed to do so.

When you handle options and other computer components, take these precautions
to avoid static electricity damage:

v Limit your movement. Movement can cause static electricity to build up around

you.

6 User Guide

v Always handle components carefully. Handle adapters and memory modules by

the edges. Never touch any exposed circuitry.

v Prevent others from touching components.

v When you install a new option, touch the static-protective package containing

the option 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 option and install it directly in the computer without

setting the option down. When this is not possible, place the static-protective
package that the option came in on a smooth, level surface and place the option
on it.

v Do not place the option on the computer cover or other metal surface.

Installing external options

This section shows the various external connectors on your computer to which you
can attach external options, such as external speakers, a printer, or a scanner. For
some external options, you must install additional software in addition to making

Appendix A. Updating system programs

This appendix contains information about updating POST/BIOS and how to
recover from a POST/BIOS update failure.

System program

System programs are the basic layer of software that is built into your computer.
They include the power-on self-test (POST), the basic input/output system (BIOS)
code, and the Setup Utility program. POST is a set of tests and procedures that is
performed each time you turn on your computer. BIOS is a layer of software that
translates instructions from other layers of software into electrical signals that the
computer hardware can understand. You can use the Setup Utility program to
view and change the configuration and setup of your computer.

Your computer system board has a module called electrically erasable programmable
read-only memory (EEPROM, also referred to as flash memory). You can easily update
POST, BIOS, and the Setup Utility program by starting your computer using a
flash update diskette or by running a special update program from your operating
system.

Lenovo might make changes and enhancements to the POST/BIOS. When updates
are released, they are available as downloadable files on the World Wide Web (see
the Quick Reference). Instructions for using the POST/BIOS updates are available in
a .txt file that is included with the update files. For most models, you can
download either an update program to create a system-program-update (flash)
diskette or an update program that can be run from the operating system.

Note: You can download a self starting bootable CD image (known as an .iso

image) of the diagnostics program from http://www.lenovo.com/support to
support systems without a diskette drive.

Updating (flashing) BIOS from a diskette

To update (flash) the BIOS from a diskette, do the following:

1. Insert a system program update (flash) diskette into the diskette drive. System

program updates are available at http://www.lenovo.com/support on the
World Wide Web.

2. Turn on the computer. If it is on already, you must turn it off and back on

again. The update begins.
