Important safety information

This information can help you safely use your IBM personal computer. Followand retain all information included with your IBM computer. The information in

this document does not alter the terms ofyour purchase agreement or the IBMStatement ofLimited Warranty.

Customer safety is important to IBM. Our products are developed tobe safe andeffective. However, personal computers are electronic devices. Power cords, poweradapters, and other features can create potential safety risks that can result inphysical injury or property damage, especially ifmisused. To reduce these risks,follow the instructions included with your product, observe all warnings on theproduct and in the operating instructions, and review the information included inthis document carefully. By carefully following the information contained in thisdocument and provided with your product, you can help protect yourselffromhazards and create a safer computer work environment.

Note: This information includes references to power adapters andbatteries. Inaddition to mobile personal computers, IBM ships some products (such as speakersor monitors) with external power adapters. Ifyou have such a product, thisinformation applies to your product. In addition, your computer product maycontain a coin-sized internalbattery that provides power to your system clock evenwhen the machine is unplugged, so thebattery safety information applies to allcomputers.

Conditions that require immediate action

Products can become damaged due to misuse or neglect. Some product damageis 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 isturned on. On very rare occasions, you might notice an odor or see a puff ofsmoke or sparks vent from your machine. Or you might hear sounds likepopping, cracking or hissing. These conditions might merely mean that aninternal electronic component has failed in a safe and controlled manner. Or,they might indicate a potential safety issue. However, do not take risks orattempt to diagnose the situation yourself.

Frequently inspect your computer and its components for damage or wear orsigns 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 itrepaired, if necessary.

In the unlikely event that you notice any of the conditions listed below, or ifyou have any safety concerns with your product, stop using the product andunplug it from the power source and telecommunication lines until you canspeak to the IBM Support Center for further guidance.

v Power cords, plugs, power adapters, extension cords, surge protectors, or powersupplies that are cracked,broken or damaged.

v Signs ofoverheating, smoke, sparks or fire.

Copyright IBM Corp. 2004 v


8/62

v Damage to abattery (such as cracks, dents, creases), discharge from abattery, orabuildup offoreign substances on thebattery.

v A cracking, hissing or popping sound, or strong odor that comes from theproduct.

v Signs that liquid hasbeen spilled or an object has fallen onto the computerproduct, the power cord or power adapter.

v

The computer product, the power cord or power adapter hasbeen exposed towater.

v The product hasbeen dropped or damaged in any way.

v The product does not operate normally when you follow the operatinginstructions.

Note: Ifyou notice these conditions with a non-IBM product (such as an extensioncord), stop using that product until you can contact the product manufacturer forfurther instructions, or until you get a suitable replacement.

General safety guidelines

Always observe the following precautions to reduce the risk ofinjury and propertydamage.

ServiceDo not attempt to service a product yourselfunless instructed to do soby the IBMSupport Center. Use only an IBM authorized service provider who is approved torepair your particular product.

Note: Some parts canbe upgraded or replacedby the customer. These parts arereferred to as Customer Replaceable Units, or CRUs. IBM expressly identifies CRUsas such, and provides documentation with instructions when it is appropriate forcustomers to replace those parts. You must closely follow all instructions whenperforming such replacements. Always make sure that the power is turned offandthat the product is unplugged from any power sourcebefore you attempt thereplacement. Ifyou have any questions or concerns, contact the IBM SupportCenter.

Power cords and power adaptersUse only the power cords and power adapters suppliedby the productmanufacturer.

Never wrap a power cord around the power adapter or other object. Doing so canstress the cord in ways that can cause the cord to fray, crack or crimp. This canpresent a safety hazard.

Always route power cords so that they will notbe walked on, tripped over, orpinchedby objects.

Protect the cord and power adapters from liquids. For instance, do not leave yourcord or power adapter near sinks, tubs, toilets, or on floors that are cleaned withliquid cleansers. Liquids can cause a short circuit, particularly ifthe cord or poweradapter hasbeen stressedby misuse. Liquids can also cause gradual corrosion ofthe power cord terminals and/or the connector terminals on the adapter which caneventually result in overheating.

vi User Guide


9/62

Always connect power cords and signal cables in the correct order and ensure thatall 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/orshows signs ofoverheating (such as deformed plastic) at the ac input or anywhereon the power adapter.

Do not use any power cords where the electrical contacts on either end show signsofcorrosion or overheating or where the power cord appears to havebeendamaged in any way.

Extension cords and related devicesEnsure that extension cords, surge protectors, uninterruptible power supplies, andpower strips that you use are rated to handle the electrical requirements oftheproduct. Never overload these devices. Ifpower strips are used, the load shouldnot exceed the power strip input rating. Consult an electrician for moreinformation ifyou have questions about power loads, power requirements, andinput ratings.

Plugs and outletsIfa receptacle (power outlet) that you intend to use with your computerequipment appears tobe damaged or corroded, do not use the outlet until it isreplacedby a qualified electrician.

Do notbend or modify the plug. Ifthe plug is damaged, contact the manufacturerto obtain a replacement.

Some products are equipped with a three-pronged plug. This plug fits only into agrounded electrical outlet. This is a safety feature. Do not defeat this safety feature

by trying to insert it into a non-grounded outlet. Ifyou cannot insert the plug intothe 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 ofthebranch circuit rating.Consult an electrician for more information ifyou have questions about powerloads andbranch 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 thatwill stress the cords.

Connect and disconnect the equipment from the electrical outlet carefully

BatteriesAll IBM personal computers contain a non-rechargeable coin cell battery to provide

power to the system clock. In addition many mobile products such as Thinkpadnotebook PCs utilize a rechargeablebattery pack to provide system power when inportable mode. Batteries suppliedby IBM for use with your product havebeentested for compatibility and should onlybe replaced with IBM approved parts.

Never attempt to open or service anybattery. Do not crush, puncture, or incineratebatteries or short circuit the metal contacts. Do not expose thebattery to water orother liquids. Only recharge thebattery pack strictly according to instructionsincluded in the product documentation.

Important safety information vii


10/62

Battery abuse or mishandling can cause thebattery to overheat, which can causegasses or flame to vent from thebattery pack or coin cell. Ifyourbattery isdamaged, or ifyou notice any discharge from yourbattery or thebuildup offoreign materials on thebattery leads, stop using thebattery and obtain areplacement from thebattery manufacturer.

Batteries can degrade when they are left unused for long periods oftime. For some

rechargeablebatteries (particularly Lithium Ionbatteries), leaving abattery unusedin a discharged state could increase the risk ofabattery short circuit, which couldshorten the life ofthebattery and can also pose a safety hazard. Do not letrechargeable Lithium-Ionbatteries completely discharge or store thesebatteries in adischarged state.

Heat and product ventilationComputers generate heat when turned on and whenbatteries are charging.Notebook PCs can generate a significant amount ofheat due to their compact size.Always follow thesebasic precautions:v Do not leave thebase ofyour computer in contact with your lap or any part of

yourbody for an extended period when the computer is functioning or when

thebattery is charging. Your computer produces some heat during normaloperation. Extended contact with thebody could cause discomfort or, potentially,a skinburn.

Handling static-sensitive devices

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

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

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

v Limit your movement. Movement can cause static electricity tobuild up aroundyou.



22/62

v Always handle components carefully. Handle adapters and memory modulesbythe edges. Never touch any exposed circuitry.

v Prevent others from touching components.

v When you install a new option, touch the static-protective package containingthe option to a metal expansion-slot cover or other unpainted metal surface onthe computer for at least two seconds. This reduces static electricity in the

package and yourbody.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-protectivepackage that the option came in on a smooth, level surface and place the optionon 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 youcan attach external options, such as external speakers, a printer, or a scanner. Forsome external options, you must install additional software in addition to makingthe physical connection. When adding an external option, use the information inthis section to identify the required connector, and then use the instructions thatcome with the option to help you make the connection and install any software ordevice drivers that are required for the option.
