Handling the ThinkPad computer

By using common sense and by following these handling tips, you will get the most use and enjoyment out of your computer for a long time to come. This section provides tips for handling notebook computers in general. Some descriptions might not suit your situation. Check your shipping checklist to confirm the items you get with your computer. Notebook computers are precision machines that require careful handling. Though your computer is designed and tested to be a durable notebook computer that functions reliably in normal work environments, you need to use some common sense in handling it.

ThinkPad don'ts

Do not subject your computer to physical punishment, such as dropping or bumping. Do not place heavy objects on your computer. Do not spill or allow liquids into your computer. Do not use your computer in or near water (to avoid the danger of electrical shock). Do not pack your computer in a tightly packed suitcase or bag. Your LCD might be damaged. A scratchlike marking on your LCD might be a stain transferred from the keyboard (including from the TrackPoint stick) when the cover was pressed from the outside. Wipe such a stain gently with a dry soft cloth. If the stain remains, moisten the cloth with LCD cleaner and wipe the stain again. Be sure to dry the LCD before closing it. Do not disassemble your computer. Only an authorized IBM ThinkPad repair technician should disassemble and repair your computer. Do not scratch, twist, hit, or push the surface of your computer display. Do not place any objects between the display and the keyboard or under the keyboard. Do not pick up or hold your computer by the display. When picking up your open computer, hold it by the bottom (keyboard) half. Copyright IBM Corp. 2000 xi, Do not modify or tape the latches to keep the display open or closed. Do not turn your computer over while the ac adapter is plugged in. This could break the adapter plug. Do not move the computer when the hard disk drive is accessing data (when the indicator is blinking). Do not use or store your computer where the temperature is below 5° C or above 35° C (41° F and 95° F). Do not place your computer closer than 13 cm (5 in.) to any electrical appliance that generates a strong magnetic field, such as a motor, a magnet, a TV, a refrigerator, or large audio speakers. Do not put an operating cellular phone on the computer. The phone might cause a computer system malfunction. Do not hard-mount your computer in a vehicle or anywhere that it is subject to strong vibration. Do not crush, drop, or physically punish the external or removable hard disk, diskette, or CD-ROM drive when it is outside your computer. Do not press on the middle part of the diskette drive or the CD-ROM drive. Do not insert a diskette at an angle. Not inserting the diskette straight into the drive can damage the drive. Do not place more than one label on a diskette, and do not allow the label to be loose. Multiple or loose labels can detach or tear and then lodge in the drive. Do not touch the lens on the CD-ROM tray. Do not close the CD-ROM tray until you hear the CD-ROM click into the center pivot of the CD-ROM drive. Do not touch the surface of a compact disc; handle the compact disc only by its edges. Do not connect the modem to a PBX (private branch exchange) or other digital telephone extension line. Your computer can use only a public-switched telephone network (PSTN). Use of a phone line other than PSTN can damage your modem. If you are not sure which kind of phone line you are using, contact your telephone company. Many hotels or office buildings use digital telephone extension lines, so check before connecting the telephone cable in such places. 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 xii IBM ThinkPad A20 User's Reference, 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.

T hinkPad do's

Treat your computer like precision electronic machinery. When installing your hard disk, diskette, or CD-ROM drive, follow the instructions in this online book and apply pressure only where needed on the device. When installing the CD-ROM or diskette drive into the UltraslimBay, make sure the ac adapter is disconnected from your computer. If you exchange drives in your computer, reinstall the plastic bezel faces (if supplied). Store your external and removable hard disk, diskette, and CD-ROM drives in the appropriate container or packaging when they are not being used. Choose a quality carrying case that will protect your computer. Store packing materials safely out of reach of children to prevent the risk of suffocation from plastic bags. Register your ThinkPad products with IBM (refer to the Web pages: http://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 upgrades. Check the IBM Web pages (http://www.ibm.com/thinkpad) periodically to get current information about your computer.

Cleaning your computer

Occasionally clean your computer as follows: Use a soft cloth moistened with nonalkaline detergent to wipe the exterior of the computer. Don't spray cleaner directly on the display or keyboard. Gently wipe the LCD with a dry, soft cloth. Handling the ThinkPad computer xiii,

Carrying your computer

When carrying your computer, follow these instructions to prevent possible damage to your computer and data: 1. Remove any media from the CD-ROM drive or diskette drive. 2. Turn off all attached devices. 3. Power off the computer, or enter suspend or hibernation mode; then close the LCD. Make sure the suspend indicator is on when the computer is in suspend mode, or the power indicator is off when it is powered off or in hibernation mode. 4. Unplug all external cables and cords connected to your computer. 5. Make sure all computer doors and covers are closed. 6. Use a quality carrying case that provides adequate cushion and protection. Do not move the computer when the hard disk drive is accessing data—that is, when the indicator is blinking. Make sure the indicator is off before you carry the computer.

Extending the life of your computer's battery

The amount of battery power consumed by your computer depends on such conditions as the frequency of use, the operating temperature, and the period in storage (if unused). The following tips can help you to extend the life of your battery: Do not recharge the battery pack until all of its power is used. Recharging a battery pack that is not completely discharged can shorten battery life. Once you start charging the battery pack, do not use it until it is fully charged. Whenever possible, use the ThinkPad battery power-saving modes: – Screen blank – Standby – Hibernation For more information, refer to the online user's guide: Decrease the LCD brightness. Use power management. Each operating system comes with its own power management. xiv IBM ThinkPad A20 User's Reference, If the internal serial devices—the modem, the serial port, and the infrared port—are not in use, stop the supply of power to them. If you will not be using the computer for a long period, remove the battery pack and keep it in a cool place. Handling the ThinkPad computer xv, xvi IBM ThinkPad A20 User's Reference,

Using password

To make sure only authorized persons may work on your computer, you can set different kinds of passwords. Then prospective users will have to know the proper passwords in order to access your computer or data. You can set the following passwords in your computer: Power-on password Screen saver password Hard-disk passwords Windows password Supervisor password Network password

Power-on password

You can set a power-on password to help prevent unauthorized users from starting up your ThinkPad computer. If you set a power-on password, the password prompt appears on the screen whenever you turn on the computer. You must enter the correct password to start using the computer. Note: If you forget your power-on password, you cannot reset it. You must take the computer to an IBM reseller or IBM marketing representative to have the password canceled. To set a power-on password, refer to the online user's guide.

Screen saver password

You can set a screen saver password. Once the screen saver has started, only those who know the password can close the screen saver and resume operating the computer. Note: The screen saver password does not thoroughly protect your computer against unauthorized users. By turning your computer off and then on again, an unauthorized user could restart Windows without knowing your screen saver password—unless you have also set a power-on password. To set a screen saver password, refer to the online user's guide. 10 IBM ThinkPad A20 User's Reference, Using password

Hard-disk passwords

Two types of hard-disk passwords help protect the information on your hard disk. When either of the hard-disk passwords has been set, the information on your hard disk cannot be accessed without one of the passwords. These are the two types of hard-disk password: User hard-disk password Master hard-disk password—which requires a user password. When a user hard-disk password is set, no one can access files and applications on the hard disk without first typing the password. The master hard-disk password is for use by systems administrators. First set a master password that only the administrator knows. Then set a user password that can be told to the user. The user can change the user password. The master password, like a master key, enables the administrator to access the hard disk even if the user has changed the user password. Attention If you forget your hard-disk password, there is no way to reset your password or recover data from the hard disk. You must take your computer to an IBM reseller or marketing representative to replace the hard-disk drive. A fee will be charged for parts and service. To set a hard-disk password, refer to the online user's guide.

W indows password

When you start your ThinkPad computer and Windows operating system opens, Windows will require you to enter a user ID and a password. To set a Windows password, refer to the online user's guide. Chapter 2. Protecting your computer 11, Using password

Supervisor password

The supervisor password protects the system information stored in the IBM BIOS Setup Utility so that, without knowing the password, no one can change the configuration of the computer. Attention If you forget your supervisor password, there is no way to reset it. You must take your computer to an IBM reseller or marketing representative to replace the system board. A fee will be charged for parts and service. To establish a setup password, refer to the online user's guide.

N etwork password

If you work on a local area network (LAN) with your ThinkPad computer, your LAN administrator might have set passwords to restrict access to various parts of the network. If you are authorized to access restricted areas of your LAN, you will need to establish a logon password in Windows. To establish your network password in Windows, refer to the online user's guide.

Passwords and standby mode

If you have set passwords and you put your computer into standby by pressing Fn+F4, you can resume operating the computer by pressing the Fn key. You will be prompted to type your password. To unlock your computer, you must enter a power-on password or a supervisor password (if one is set). If one or more hard disks has a hard-disk password, the disks are unlocked automatically when you resume your computer. For information on hard-disk passwords with a hard disk in a docking station, refer to the online user's guide. 12 IBM ThinkPad A20 User's Reference, Using the locks and the security screw

Using the locks and the security screw Attaching the mechanical lock

You can attach a mechanical lock to your computer, to help prevent it from being removed without your permission. Attach a mechanical lock to the keyhole of the computer; then secure the chain on the lock to a stationary object. Refer to the instructions shipped with the mechanical lock. Note: You are responsible for evaluating, selecting, and implementing the locking devices and security features. IBM makes no comments, judgments, or warranties about the function, quality, or performance of locking devices and security features.

Using the security screw

The security screw shipped with your computer can help prevent the hard-disk drive from being removed. To replace the coin screw with the security screw, do as follows: 1. Turn off the computer; then disconnect the ac adapter and all cables from the computer. 2. Remove the screw with a coin; then install the security screw, and tighten it with a 2.5-mm allen wrench. 3. Connect the ac adapter; then turn on the computer. Chapter 2. Protecting your computer 13, Using the Asset RF ID feature

Using the Asset RF ID feature

The Asset ID RF feature, available as an option, contains Asset ID technology, which you can think of as the next generation of bar code technology. This option enables communication between the ThinkPad computer and an industry-standard radio-frequency hand-held device, called a reader hereafter in this manual. The option provides better management, deployment, and security of your ThinkPad computer inventory. After this option is installed in your computer, the reader can recognize the following information: Serial numbers: System board System unit Configuration information: UUID MAC address CPU data DIMM data Diskette drive data IDE device data PCI device data ISA Plug and Play device data LCD panel data Docking station data A reader can also recognize the following user information after it has been set in your computer: User name Telephone number Machine lease data This option can also be used to prevent your computer from being stolen. It is effective only when the supervisor password is set. If you use this option for security, you need to enable RFID security after installing it into your computer.

Statement of limited warranty

The warranties provided by IBM in this Statement of Limited Warranty apply only to Machines you originally purchase for your use, and not for resale, from IBM or an IBM authorized reseller. The term “Machine” means an IBM machine, its features, conversions, upgrades, elements, or accessories, or any combination of them. Machines are subject to these terms only if purchased in the United States or Puerto Rico, or Canada, and located in the country of purchase. If you have any questions, contact IBM or your reseller. Machine: IBM ThinkPad A20 and the Battery Pack Warranty period*: Model 2628: One Year Model 2629: Three Years except in some countries Model 2633: Three Years Battery Pack: One Year *Elements and accessories are warranted for three months. Contact your place of purchase for warranty service information. Production status Each Machine is manufactured from new parts, or new and serviceable used parts (which perform like new parts). In some cases, the Machine may not be new and may have been previously installed. Regardless of the Machine's production status, IBM's warranty terms apply. The IBM warranty IBM warrants that each Machine 1) is free from defects in materials and workmanship and 2) conforms to IBM's Official Published Specifications. IBM calculates the expiration of the warranty period from the Machine's Date of Installation. The date on your receipt is the Date of Installation, unless IBM or your reseller informs you otherwise. During the warranty period, IBM or your reseller will provide warranty service under the type of service designated for the Machine and will manage and install engineering changes that apply to the Machine. IBM or your reseller will specify the type of service. For a feature, conversion, or upgrade, IBM or your reseller may require that the Machine on which it is installed be 1) the designated, serial-numbered Machine and 2) at an engineering-change level compatible with the feature, conversion, or upgrade. Some of these transactions (called “Net-Priced” transactions) may include additional parts and associated replacement parts that are provided on an exchange basis. All removed parts become the property of IBM and must be returned to IBM. Replacement parts assume the remaining warranty of the parts they replace. If a Machine does not function as warranted during the warranty period, IBM or your reseller will repair or replace it (with a Machine that is at least functionally equivalent) without charge. If IBM or your reseller is unable to do so, you may return it to your place of purchase and your money will be refunded. If you transfer a Machine to another user, warranty service is available to that user for the remainder of the warranty period. You should give your proof of purchase and this Statement to that user. Warranty service To obtain warranty service for the Machine, you should contact your reseller or call IBM. In the United States, call IBM at 1-800-772-2227. In Canada, call IBM at 1-800-565-3344. You may be required to present proof of purchase. Depending on the Machine, the service may be 1) a “Repair” service at your location (called “On-site”) or at one of IBM's or a reseller's service locations (called “Carry-in”) or 2) an “Exchange” service, either On-site or Carry-in. When a type of service involves the exchange of a Machine or part, the item IBM or your reseller replaces becomes its property and the replacement becomes yours. The replacement may not be new, but will be in good working order and at least functionally equivalent to the item replaced. Copyright IBM Corp. 2000 39,

Product warranty

It is your responsibility to: 1. obtain authorization from the owner (for example, your lessor) to have IBM or your reseller service a Machine that you do not own; 2. where applicable, before service is provided — a) follow the problem determination, problem analysis, and service request procedures that IBM or your reseller provide, b) secure all programs, data, and funds contained in a Machine, c) inform IBM or your reseller of changes in a Machine's location, and d) for a Machine with exchange service, remove all features, parts, options, alterations, and attachments not under warranty service. Also, the Machine must be free of any legal obligations or restrictions that prevent its exchange; and 3. be responsible for loss of, or damage to, a Machine in transit when you are responsible for the transportation charges. Extent of warranty IBM does not warrant uninterrupted or error-free operation of a Machine. Unless IBM specifies otherwise, IBM provides non-IBM machines on an “AS IS” basis. However, non-IBM manufacturers may provide their own warranties to you. Misuse, accident, modification, unsuitable physical or operating environment, improper maintenance by you, removal of product labels or parts identification labels, or failure caused by a product for which IBM is not responsible may void the warranties. THESE WARRANTIES REPLACE ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. HOWEVER, SOME LAWS DO NOT ALLOW THE EXCLUSION OF IMPLIED WARRANTIES. IF THESE LAWS APPLY, THEN ALL EXPRESS AND IMPLIED WARRANTIES ARE LIMITED IN DURATION TO THE WARRANTY PERIOD. NO WARRANTIES APPLY AFTER THAT PERIOD. In Canada, warranties include both warranties and conditions. Some jurisdictions do not allow limitations on how long an implied warranty lasts, so the above limitation may not apply to you. Limitation of liability Circumstances may arise where, because of a default on IBM's part (including fundamental breach) or other liability (including negligence and misrepresentation), you are entitled to recover damages from IBM. In each such instance, regardless of the basis on which you are entitled to claim damages, IBM is liable only for: 1. bodily injury (including death), and damage to real property and tangible personal property; and 2. the amount of any other actual loss or damage, up to the greater of $100,000 or the charge for the Machine that is the subject of the claim. Under no circumstances is IBM liable for any of the following: 1. third-party claims against you for losses or damages (other than those under the first item listed above); 2. loss of, or damage to, your records or data; or 3. economic consequential damages (including lost profits or savings) or incidental damages, even if IBM is informed of their possibility. Some jurisdictions do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you.

Notices Telecommunication notices 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 Part 68 of the FCC Rules. A label is affixed to the bottom of the computer that contains, among other things, the FCC registration number, USOC, and Ringer Equivalency Number (REN) for this equipment. If these numbers are requested, look at the label and provide this information to your telephone company. 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 isn't 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. 9. When ordering network interface (NI) service from the Local Exchange Carrier, specify service arrangement USOC RJ11C. Appendix A. Product warranty and notices 45,

The Telephone Consumer Protection Act of 1991 makes it unlawful for any person to use a computer or other electronic device, including fax machines, to send any message unless such message clearly contains in a margin at the top of 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.

Notices Industry Canada requirements N otice

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 user's 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 company's 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.

C aution

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.

L'étiquette du ministère de l'Industrie Canada identifie le matériel homologué. Cette étiquette certifie que le matériel est conforme à certaines normes de protection, d'exploitation et de sécurité des réseaux de télécommunications. Le Ministère n'assure toutefois pas que le matériel fonctionnera à la satisfaction de l'utilisateur. Avant d'installer ce matériel, l'utilisateur doit s'assurer qu'il est permis de le raccorder aux installations de l'entreprise locale de télécommunication. Le matériel doit également être installé en suivant une méthode acceptée de raccordement. Dans certains cas, les fils intérieurs de l'entreprise utilisés pour un service individuel à ligne unique peuvent être prolongés au moyen d'un dispositif homologué de raccordement (cordon prolongateur téléphonique interne).

Les réparations de matériel homologué doivent être effectuées par un centre d'entretien canadien autorisé désigné par le fournisseur. La compagnie de télécommunications peut demander à l'utilisateur de débrancher un appareil à la suite de réparations ou de modifications effectuées par l'utilisateur ou à cause de mauvais fonctionnement. Pour sa propre protection, l'utilisateur doit s'assurer que tous les fils de mise à la terre de la source d'énergie électrique, des lignes téléphoniques et des canalisations d'eau métalliques, s'il y en a, sont raccordés ensemble. Cette précaution est particulièrement importante dans les régions rurales.

Avertissement

L'utilisateur ne doit pas tenter de faire ces raccordements lui-même; il doit avoir recours à un service d'inspection des installations électriques, ou à électricien, selon le cas. L'indice de charge (IC) assigné à chaque dispositif terminal indique (REN:0.3), pour éviter toute surcharge, le pourcentage de la charge totale qui peut être raccordée à un circuit téléphonique bouclé utilisé par ce dispositif. La terminaison du circuit bouclé peut être constituée de n'importe quelle combinaison de dispositifs, pourvu que la somme des indices de charge de l'ensemble des dispositifs ne dépasse pas 5. 48 IBM ThinkPad A20 User's Reference,
