Caring for your ThinkPad computer  
Caring for your ThinkPad computer  
Though your computer is designed to function reliably in normal work  
environments, you need to use common sense in handling it. By following  
these important tips, you will get the most use and enjoyment out of your  
computer.  
Important tips:  
Be careful about where and how you work  
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 dissipates some heat during  
normal operation. This heat is a function of the level of system activity and  
battery charge level. Extended contact with your body, even through  
clothing, could cause discomfort or, eventually, a skin burn.  
v Place liquids away from your computer to avoid spills, and keep your  
computer away from water (to avoid the danger of electrical shock).  
v Store packing materials safely out of the reach of children to prevent the  
risk of suffocation from plastic bags.  
v Keep your computer away from magnets, activated cellular phones,  
electrical appliances, or speakers (within 13cm/ 5 in).  
v Avoid subjecting your computer to extreme temperatures (below 5°C/ 41°F  
or above 35°C/ 95°F).  
Be gentle with your computer  
v Avoid placing any objects (including paper) between the display and the  
keyboard or under the keyboard.  
v Do not drop, bump, scratch, twist, hit, vibrate, push or place heavy objects  
on your computer, display, or external devices.  
v Your computer display is designed to be opened and used at an angle  
slightly greater than 90 degrees. Do not open the display beyond 135  
degrees, as this might damage the computer hinge.  
Carry your computer properly  
v Before moving your computer, be sure to remove any media, turn off  
attached devices, and disconnect cords and cables.  
v Be sure your computer is in standby or hibernation mode, or turned off,  
before moving it. This will prevent damage to the hard disk drive and data  
loss.  
v When picking up your open computer, hold it by the bottom. Do not pick  
up or hold your computer by the display.

Caring for your ThinkPad computer  
v Use a quality carrying case that provides adequate cushion and protection.  
Do not pack your computer in a tightly packed suitcase or bag.  
Handle storage media and drives properly  
v If your computer comes with a diskette drive, avoid inserting diskettes at  
an angle and attaching multiple or loose diskette labels, as these can lodge  
in the drive.  
v If your computer comes with a CD-ROM or DVD-ROM drive, do not touch  
the surface of a CD or the lens on the CD-ROM or DVD-ROM tray.  
v Wait until you hear the CD- or DVD-ROM click into the center pivot of the  
CD- or DVD-ROM drive before closing the CD- or DVD-ROM tray  
v When installing your hard disk, diskette, CD-ROM, or DVD-ROM drive,  
follow the instructions shipped with your hardware, and apply pressure  
only where needed on the device. See Access ThinkPad, your on-board help  
system, for information on replacing your hard disk drive (open Access  
ThinkPad by pressing the ThinkPad button).  
Take care in setting passwords  
v Remember your passwords. If you forget a supervisor or hard disk  
password, IBM will not reset it, and you may have to replace your hard  
disk drive.  
v If you are an administrator, remember that setting a supervisor password  
can prevent unauthorized initialization or changing of hard disk drive  
passwords.  
Other important tips  
v Your computer modem may use only an analog telephone network, or  
public-switched telephone network (PSTN). Do not connect the modem to a  
PBX (private branch exchange) or any other digital telephone extension line  
because this could damage your modem. Analog phone lines are often used  
in homes, while digital phone lines are often used in hotels or office  
buildings. If you are not sure which kind of phone line you are using,  
contact your telephone company.  
v Your computer might have both an Ethernet connector and a modem  
connector. If so, be sure to connect your communication cable to the correct  
one, so your connector is not damaged. See Access ThinkPad, your  
on-board help system, for information on the location of these connectors  
(press the ThinkPad button to open Access ThinkPad).  
v Register your ThinkPad products with IBM (refer to the Web page:  
www.pc.ibm.com/register). This can help authorities return your computer  
to you if it is lost or stolen. Registering your computer also enables IBM to  
notify you about possible technical information and upgrades.

Caring for your ThinkPad computer  
v Only an authorized IBM ThinkPad repair technician should disassemble  
and repair your computer.  
v Do not modify or tape the latches to keep the display open or closed.  
v Take care not to turn your computer over while the ac adapter is plugged  
in. This could break the adapter plug.  
v Turn off your computer if you are replacing a device in a device bay, or else  
verify that the device is warm- or hot-swappable.  
v If you exchange drives in your computer, reinstall the plastic bezel faces (if  
supplied).  
v Store your external and removable hard disk, diskette, CD-ROM, and  
DVD-ROM drives in the appropriate containers or packaging when they are  
not being used.  
Cleaning your computer  
Occasionally clean your computer as follows:  
v Use a soft cloth moistened with nonalkaline detergent to wipe the exterior  
of the computer.  
v Avoid spraying cleaner directly on the display or the keyboard.  
v Gently wipe the display with a dry, soft cloth.

Solving computer problems  
Diagnosing problems  
If you have a problem with your computer, you can test it by using  
PC-Doctor for Windows. To run PC-Doctor for Windows, do as follows:  
1. Click Start.  
2. Move the cursor to Programs and then to PC-Doctor for Windows.  
3. Click PC-Doctor for Windows.  
4. Choose either the Quick Test or the Standard Test.  
Attention  
Running the Quick Test set can take 10 minutes or longer. Make sure  
you have time to run the entire test; do not interrupt the test while it is  
running.  
The Quick Test set runs many tests of critical hardware components, but it  
does not run all of the diagnostic test in PC-Doctor for Windows. If PC-Doctor  
for Windows reports that all of the tests in the Quick Test set have been run  
and that it has found no problems, consider running addi-tional tests.  
If you are preparing to contact IBM for support, be sure to print the test log  
so that you can rapidly provide information to the help technician.

computer queries the Ethernet until the timeout timer stops the query. If you  
want to access an Ethernet, connect the network cable. If you are not using  
the network, disable the Ethernet port as follows:

The generic CD-ROM or DVD-ROM driver for Windows 98 accesses the  
internal CD-ROM drive or DVD-ROM drive every 3 seconds to see if a  
CD-ROM is inserted in the CD-ROM drive or DVD-ROM drive. This prevents  
your computer from entering standby mode even after a timeout. To prevent  
this from occurring, do the following:  
1. Click Start.  
2. Move the cursor to Settings and Control Panel.  
3. Click Control Panel, and then double-click System.  
4. Click the Device Manager tab.  
5. Click the + mark of CD-ROM.  
6. Double-click the name of the CD-ROM or DVD-ROM.  
7. Click the Setting tab.

Federal Communications Commission (FCC) and Telephone Company  
Requirements (Part 68 of the FCC Rules)  
1. The Telephone Consumer Protection Act of 1991 makes it unlawful for any  
person to use a computer or other electronic device to send any message  
via a telephone fax machine unless such message clearly contains in a  
margin at the top or bottom of each transmitted page or on the first page  
of the transmission, the date and time it is sent, and an identification of  
the business or other entity, or other individual sending the message and  
the telephone number of the sending machine or such business, other  
entity, or individual.  
In order to program this information into your computer, you should be  
sure to follow the installation instructions for your fax software package.  
2. The built-in modem is built into the ThinkPad computer. It complies with

3. The REN is useful to determine the quantity of devices you may connect  
to your telephone line and still have those devices ring when your number  
is called. In most, but not all, areas, the sum of the RENs of all devices  
should not exceed five (5.0). To be certain of the number of devices you  
may connect to your line, as determined by the REN (REN:0.7), you  
should call your local telephone company to determine the maximum REN  
for your calling area.  
4. If the built-in modem causes harm to the telephone network, the telephone  
company may discontinue your service temporarily. If possible, they will  
notify you in advance. But, if advance notice isnt practical, you will be  
notified as soon as possible. You will be advised of your right to file a  
complaint with the FCC.  
5. Your telephone company may make changes in its facilities, equipment,  
operations, or procedures that could affect the proper operation of your  
equipment. If they do, you will be given advance notice so as to give you  
an opportunity to maintain uninterrupted service.  
6. If you experience trouble with this built-in modem, contact your IBM  
Authorized Seller, or the IBM Corporation, 500 Columbus Avenue,  
Thornwood, NY 10594, 1-800-772-2227, for repair/ warranty information.  
The telephone company may ask you to disconnect this equipment from  
the network until the problem has been corrected, or until you are sure the  
equipment is not malfunctioning.  
7. No customer repairs are possible to the modem. If you experience trouble  
with this equipment, contact your Authorized Seller or the IBM  
Corporation for information.  
8. The modem may not be used on coin service provided by the telephone  
company. Connection to party lines is subject to state tariffs. Contact your  
state public utility commission or corporation commission for information.

Industry Canada requirements  
Notice  
The Industry Canada label identifies certified equipment. This certification  
means that the equipment meets certain telecommunications networks  
protective, operational, and safety requirements. The Department does not  
guarantee the equipment will operate to the users satisfaction.  
Before installing this equipment, users should ensure that it is permissible to  
be connected to the facilities of the local telecommunications company. The  
equipment must also be installed using an acceptable method of  
communication. In some cases, the companys inside wiring associated with a  
single line individual service may be extended by means of a certified  
connector assembly (telephone extension cord). The customer should be aware  
that compliance with the above conditions may not prevent degradation of  
service in some situations.  
Repairs to certified equipment should be made by an authorized Canadian  
maintenance facility designated by the supplier. Any repairs of alterations  
made by the user to this equipment, or equipment malfunctions, may give the  
telecommunications company cause to request the user to disconnect the  
equipment.  
Users should ensure for their own protection that the electrical ground  
connections of the power utility, telephone lines and internal metallic water  
pipe system, if present, are connected together. This precaution may be  
particularly important in rural areas.  
Caution  
Users should not attempt to make such connections themselves, but should  
contact the appropriate electric inspection authority, or electrician, as  
appropriate.  
The Ringer Equivalent Number (REN:0.3) assigned to each terminal device  
provides an indication of the maximum number of terminals allowed to be  
connected to a telephone interface. The termination on an interface may  
consist of any combination of devices subject only to the requirement that the  
sum of the Ringer Equivalence Number of all the devices does not exceed 5.

raccorder aux installations de lentreprise locale de télécommunication. Le  
matériel doit également être installé en suivant une méthode acceptée de  
raccordement. Dans certains cas, les fils intérieurs de lentreprise utilisés pour  
un service individuel à ligne unique peuvent être prolongés au moyen dun  
dispositif homologué de raccordement (cordon prolongateur téléphonique  
interne). Labonné ne doit pas oublier quil est possible que la conformité aux  
conditions énoncées ci-dessus nempechent pas la dégradation du service dans  
certaines situations. Actuellement, les entreprises de télécommunication ne  
permettent pas que lon raccorde leur matériel à des jacks dabonné, sauf dans  
les cas précis prévus par les tarifs paticuliers de ces entreprises.  
Les réparations de matériel homologué doivent être effectuées par un centre  
dentretien canadien autorisé désigné par le fournisseur. La compagnie de  
télécommunications peut demander à lutilisateur de débrancher un appareil à  
la suite de réparations ou de modifications effectuées par lutilisateur ou à  
cause de mauvais fonctionnement.  
Pour sa propre protection, lutilisateur doit sassurer que tous les fils de mise  
à la terre de la source d’énergie électrique, des lignes téléphoniques et des  
canalisations deau métalliques, sil y en a, sont raccordés ensemble. Cette  
précaution est particulièrement importante dans les régions rurales.  
Avertissement
