Important safety information

Note

Please read important safety information first.

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. 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

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 “Help and Service” section later in 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.

The telephone numbers for your IBM Support Center location are located in

the “Help and Service” section later in this guide.

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 authorized IBM service provider who is

approved to repair your particular product.

vi Quick Reference

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 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

Important safety information vii

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.

Connect and disconnect the equipment from the electrical outlet carefully

Batteries

All 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

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 Quick Reference

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
