Introduction
Important service information
Important BIOS and device driver fixes are customer-installable. The BIOS and device drivers are posted on the IBM support site http://www.ibm.com/pc/support Advise customers to contact the PC Company HelpCenter at 800-772-2227 if they need assistance in obtaining or installing any diskette fixes. Customers in Canada should call IBM HelpPC at 800-565-3344 for assistance or download information.

Strategy for replacing FRUs
Before replacing parts Make sure that all diskette fixes are installed before replacing any FRUs listed in this manual. Use the following strategy to prevent unnecessary expense for replacing and servicing FRUs: v If you are instructed to replace a FRU but the replacement does not correct the problem, reinstall the original FRU before you continue. v Some computers have both a processor board and a system board. If you are instructed to replace either the processor board or the system board, and replacing one of them does not correct the problem, reinstall that board, and then replace the other one. v If an adapter or device consists of more than one FRU, any of the FRUs may be the cause of the error. Before replacing the adapter or device, remove the FRUs, one by one, to see if the symptoms change. Replace only the FRU that changed the symptoms. Attention: The setup configuration on the computer you are servicing may have been customized. Running Automatic Configuration may alter the settings. Note the current configuration settings (using the View Configuration option); then, when service has been completed, verify that those settings remain in effect.

Safety notices

Safety notice 7

DANGER

Though the main batteries have low voltage, a shorted or grounded battery can produce enough current to burn personnel or combustible materials. Bien que le voltage des batteries principales soit peu élevé, le court-circuit ou la mise à la masse d'une batterie peut produire suffisamment de courant pour brûler des matériaux combustibles ou causer des brûlures corporelles graves. Obwohl Hauptbatterien eine niedrige Spannung haben, können sie doch bei Kurzschluß oder Erdung genug Strom abgeben, um brennbare Materialien zu entzünden oder Verletzungen bei Personen hervorzurufen.

Sebbene le batterie di alimentazione siano a basso voltaggio, una batteria in corto circuito o a massa può fornire corrente sufficiente da bruciare materiali combustibili o provocare ustioni ai tecnici di manutenzione. Aunque las baterías principales tienen un voltaje bajo, una batería cortocircuitada o con contacto a tierra puede producir la corriente suficiente como para quemar material combustible o provocar quemaduras en el personal.

Safety information

Safety information
The following section presents the safety information that you need to be familiar with before servicing an IBM mobile computer.

General safety
Follow these rules to ensure general safety: v Observe good housekeeping in the area of the machines during and after maintenance. v When lifting any heavy object: 1. Ensure you can stand safely without slipping. 2. Distribute the weight of the object equally between your feet. 3. Use a slow lifting force. Never move suddenly or twist when you attempt to lift. 4. Lift by standing or by pushing up with your leg muscles; this action removes the strain from the muscles in your back. Do not attempt to lift any object that weighs more than 16 kg (35 lb) or objects that you think are too heavy for you. v Do not perform any action that causes hazards to the customer, or that makes the equipment unsafe. v Before you start the machine, ensure that other service representatives and the customer's personnel are not in a hazardous position. v Place removed covers and other parts in a safe place, away from all personnel, while you are servicing the machine. v Keep your toolcase away from walk areas so that other people will not trip over it. v Do not wear loose clothing that can be trapped in the moving parts of a machine. Make sure that your sleeves are fastened or rolled up above your elbows. If your hair is long, fasten it. v Insert the ends of your necktie or scarf inside clothing or fasten it with a nonconductive clip, approximately 8 centimeters (3 inches) from the end. v Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your clothing. Attention: Metal objects are good electrical conductors. v Wear safety glasses when you are hammering, drilling, soldering, cutting wire, attaching springs, using solvents, or working in any other conditions that might be hazardous to your eyes.

16

ThinkPad T30 (MT 2366, 2367)

Safety information

v After service, reinstall all safety shields, guards, labels, and ground wires. Replace any safety device that is worn or defective. v Reinstall all covers correctly before returning the machine to the customer.

Electrical safety
Observe the following rules when working on electrical equipment.

Important Use only approved tools and test equipment. Some hand tools have handles covered with a soft material that does not insulate you when working with live electrical currents. Many customers have, near their equipment, rubber floor mats that contain small conductive fibers to decrease electrostatic discharges. Do not use this type of mat to protect yourself from electrical shock. v Find the room emergency power-off (EPO) switch, disconnecting switch, or electrical outlet. If an electrical accident occurs, you can then operate the switch or unplug the power cord quickly. v Do not work alone under hazardous conditions or near equipment that has hazardous voltages. v Disconnect all power before: ­ Performing a mechanical inspection ­ Working near power supplies ­ Removing or installing main units v Before you start to work on the machine, unplug the power cord. If you cannot unplug it, ask the customer to power-off the wall box that supplies power to the machine and to lock the wall box in the off position. v If you need to work on a machine that has exposed electrical circuits, observe the following precautions: ­ Ensure that another person, familiar with the power-off controls, is near you. Attention: Another person must be there to switch off the power, if necessary. ­ Use only one hand when working with powered-on electrical equipment; keep the other hand in your pocket or behind your back. Attention: An electrical shock can occur only when there is a complete circuit. By observing the above rule, you may prevent a current from passing through your body.

Introduction

17

Safety information

­ When using testers, set the controls correctly and use the approved probe leads and accessories for that tester. ­ Stand on suitable rubber mats (obtained locally, if necessary) to insulate you from grounds such as metal floor strips and machine frames. Observe the special safety precautions when you work with very high voltages; these instructions are in the safety sections of maintenance information. Use extreme care when measuring high voltages. v Regularly inspect and maintain your electrical hand tools for safe operational condition. v Do not use worn or broken tools and testers. v Never assume that power has been disconnected from a circuit. First, check that it has been powered off. v Always look carefully for possible hazards in your work area. Examples of these hazards are moist floors, nongrounded power extension cables, power surges, and missing safety grounds. v Do not touch live electrical circuits with the reflective surface of a plastic dental mirror. The surface is conductive; such touching can cause personal injury and machine damage. v Do not service the following parts with the power on when they are removed from their normal operating places in a machine: ­ Power supply units ­ Pumps ­ Blowers and fans ­ Motor generators and similar units. (This practice ensures correct grounding of the units.) v If ­ ­ ­ an electrical accident occurs: Use caution; do not become a victim yourself. Switch off power. Send another person to get medical aid.

Safety inspection guide
The purpose of this inspection guide is to assist you in identifying potentially unsafe conditions. As each machine was designed and built, required safety items were installed to protect users and service personnel from injury. This guide addresses only those items. You should use good judgment to identify potential safety hazards due to attachment of non-IBM features or options not covered by this inspection guide.

18

ThinkPad T30 (MT 2366, 2367)

Safety information

If any unsafe conditions are present, you must determine how serious the apparent hazard could be and whether you can continue without first correcting the problem. Consider these conditions and the safety hazards they present: v Electrical hazards, especially primary power (primary voltage on the frame can cause serious or fatal electrical shock) v Explosive hazards, such as a damaged CRT face or a bulging capacitor v Mechanical hazards, such as loose or missing hardware To determine whether there are any potentially unsafe conditions, use the following checklist at the beginning of every service task. Begin the checks with the power off, and the power cord disconnected. Checklist: 1. Check exterior covers for damage (loose, broken, or sharp edges). 2. Power-off the computer. Disconnect the power cord. 3. Check the power cord for: a. A third-wire ground connector in good condition. Use a meter to measure third-wire ground continuity for 0.1 ohm or less between the external ground pin and frame ground. b. The power cord should be the type specified in the parts list. c. Insulation must not be frayed or worn. 4. Remove the cover. 5. Check for any obvious non-IBM alterations. Use good judgment as to the safety of any non-IBM alterations. 6. Check inside the unit for any obvious unsafe conditions, such as metal filings, contamination, water or other liquids, or signs of fire or smoke damage. 7. Check for worn, frayed, or pinched cables. 8. Check that the power-supply cover fasteners (screws or rivets) have not been removed or tampered with.

Handling devices that are sensitive to electorostatic discharge
Any computer part containing transistors or integrated circuits (ICs) should be considered sensitive to electrostatic discharge (ESD.) ESD damage can occur when there is a difference in charge between objects. Protect against ESD

Introduction

Safety information

damage by equalizing the charge so that the machine, the part, the work mat, and the person handling the part are all at the same charge.

Notes 1. Use product-specific ESD procedures when they exceed the requirements noted here. 2. Make sure that the ESD protective devices you use have been certified (ISO 9000) as fully effective. When handling ESD-sensitive parts: v Keep the parts in protective packages until they are inserted into the product. v Avoid contact with other people. v Wear a grounded wrist strap against your skin to eliminate static on your body. v Prevent the part from touching your clothing. Most clothing is insulative and retains a charge even when you are wearing a wrist strap. v Use the black side of a grounded work mat to provide a static-free work surface. The mat is especially useful when handling ESD-sensitive devices. v Select a grounding system, such as those listed below, to provide protection that meets the specific service requirement.

Note The use of a grounding system is desirable but not required to protect against ESD damage. ­ Attach the ESD ground clip to any frame ground, ground braid, or green-wire ground. ­ Use an ESD common ground or reference point when working on a double-insulated or battery-operated system. You can use coax or connector-outside shells on these systems. ­ Use the round ground-prong of the AC plug on AC-operated computers.

Before you go to the checkout guide, be sure to read this section.

Important notes v Only certified trained personnel should service the computer. v Read the entire FRU removal and replacement page before replacing any FRU. v Use new nylon-coated screws when you replace FRUs. v Be extremely careful during such write operations as copying, saving, or formatting. Drives in the computer that you are servicing sequence might have been altered. If you select an incorrect drive, data or programs might be overwritten. v Replace FRUs only for the correct model. When you replace a FRU, make sure the model of the machine and the FRU part number are correct by referring to the FRU parts list. v A FRU should not be replaced because of a single, unreproducible failure. Single failures can occur for a variety of reasons that have nothing to do with a hardware defect, such as cosmic radiation, electrostatic discharge, or software errors. Consider replacing a FRU only when a problem recurs. If you suspect that a FRU is defective, clear the error log and run the test again. If the error does not recur, do not replace the FRU. v Be careful not to replace a nondefective FRU.

Restoring the preloaded system
If the data on a hard-disk drive is damaged or accidentally erased, you can restore the software that was shipped with the computer. This software includes the pre-installed operating system, applications, and device drivers. To restore the pre-installed software, you can use either the Product Recovery program or a recovery CD.

Ordering the recovery CD When the hard-disk drive is replaced because of a failure, no Product Recovery program is on the new hard disk. In this case, you must use the Product Recovery CD for the computer. Order the recovery CD and the hard-disk drive at the same time so that you can recover the new hard-disk drive with the pre-installed software when they arrive. For information on which CD to order, see "Recovery CDs" on page 154 The Product Recovery program is in the service partition, a section of the hard-disk drive that is not displayed by Windows Explorer. Attention: All of the files on the primary hard-disk partition (usually drive C) will be lost in the recovery process. Be sure to back up copies of the files you have saved on your drive C before you begin.

Product Recovery program
Note: The recovery process might take up to 2 hours. To use the Product Recovery program to restore the pre-installed software, do the following: 1. Save all files and shut down the desktop. 2. Turn off the computer. General descriptions

Passwords
As many as three passwords may be needed for any ThinkPad computer: the power-on password (POP), the hard-disk password (HDP), and the supervisor password (SVP). If any of these passwords has been set, a prompt for it appears on the screen whenever the computer is turned on. The computer does not start until the password is entered. Exception: If only an SVP is installed, the password prompt does not appear when the operating system is booted.

Power-on password:
A power-on password (POP) protects the system from being powered on by an unauthorized person. The password must be entered before an operating system can be booted.

Hard-disk password:
There are two hard-disk passwords (HDPs): v User HDP--for the user v Master HDP--for the system administrator, who can use it to get access to the hard disk even if the user has changed the user HDP Note: There are two modes for the HDP: User only and Master + User. The Master + User mode requires two HDPs; the system administrator enters both in the same operation. The system administrator then provides the user HDP to the system user.

General descriptions

29

Related service information

Attention: If the user HDP has been forgotten, check whether a master HDP has been set. If it has, it can be used for access to the hard-disk drive. If no master HDP is available, IBM does not provide any services to reset either the user or the master HDP, or to recover data from the hard-disk drive. The hard-disk drive can be replaced for a scheduled fee.

Supervisor password:
A supervisor password (SVP) protects the system information stored in the IBM BIOS Setup Utility. The SVP must be entered in order to get access to the IBM BIOS Setup Utility and make changes to system configuration settings. Attention: If the SVP has been forgotten and cannot be made available to the servicer, there is no service procedure to reset the password. The system board must be replaced for a scheduled fee.

How to remove the power-on password
To remove a POP that you have forgotten, do the following: (A) If no SVP has been set: 1. Turn off the computer. 2. Remove the battery pack. For how to remove the battery pack, see "1010 Battery pack" on page 61. 3. Remove the backup battery. For how to remove the backup battery, see "1050 Backup battery" on page 67. 4. Turn on the computer and wait until the POST ends. After the POST ends, the password prompt does not appear. The POP has been removed. 5. Reinstall the backup battery and the battery pack. (B) If an SVP has been set and is known by the servicer: 1. Turn on the computer; then, while the "To interrupt normal startup, press the blue Access IBM button" message is displayed at the lower-left of the screen, press the Access IBM button. 2.

Power management
To reduce power consumption, the computer has three power management modes: screen blank, standby, and hibernation.

Notes v Screen blank mode is called standby mode in Windows NT. v Standby mode is called suspend mode in Windows NT.

Screen blank mode
Screen blank mode has three variants, as follows:

General descriptions

31

Related service information

1. If you press Fn+F3, or the time set on the "LCD off timer" in IBM BIOS Setup Utility expires, v The LCD backlight turns off. v The hard-disk drive motor stops. v The speaker is muted. 2. If you are using the ACPI operating system and you press Fn+F3, v The LCD backlight turns off. v The hard-disk drive motor stops. 3. If the time set on the "Turn off monitor" timer in the operating system expires, v The LCD backlight turns off. To end screen blank mode and resume normal operation, press any key.

Standby mode
When the computer enters standby mode, the following events occur in addition to what occurs in screen blank mode: v The LCD is powered off. v The hard-disk drive is powered off. v The CPU stops. To enter standby mode, press Fn+F4. Note: You can change the action of Fn+F4, if you are using the ACPI operating system. In certain circumstances, the computer goes into standby mode automatically: v If a "suspend time" has been set on the timer, and the user does not do any operation with the keyboard, the TrackPoint, the hard disk, the parallel connector, or the diskette drive within that time. v If the battery indicator blinks orange, indicating that the battery power is low. (Alternatively, if Hibernate when battery becomes low has been selected in the "Power Management Properties" window, the computer goes into hibernation mode.) Note for the APM operating system: Even if you do not set the low-battery alarm, the charge indicator notifies you when the battery is low, and then the computer enters the power-saving mode automatically. This default low-battery behavior is independent of the operating system; so if you have set the low-battery alarm, the computer may not do what you specified. It chooses either your setting or the default setting, whichever is appropriate.

If you are using the ACPI operating system, only the low-battery alarm is available. To cause the computer to return from standby mode and resume operation, do one of the following: v Press the Fn key. v Open the LCD cover. v Turn on the power switch. Also, the computer automatically returns from standby mode and resumes operation in either of the following events: v The ring indicator (RI) is signaled by a serial device or a PC Card device (Windows 2000 does not support the ring indicator (RI) resume by PC Card device.) v The time set on the resume timer elapses. In Windows 98, the Scheduled Tasks setting takes priority over the Resume on timer selection in the "Power Management Properties" window. Note: The computer does not accept any input immediately after it enters standby mode. Wait a few seconds before taking any action to reenter operation mode.

Hibernation mode
Note for Windows NT If you are using Windows NT in NTFS format, you cannot create a hibernation file. If you want to use hibernation mode, you will need to reinstall Windows NT with FAT format.

Note for OS/2 If you are using OS/2 in the default format, HPFS, you cannot create a hibernation file. If you want to use hibernation mode, you will need to reinstall OS/2 with FAT format. In hibernation mode, the following occurs: v The system status, RAM, VRAM, and setup data are stored on the hard disk. v The system is powered off. Note: If the computer enters the hibernation mode while it is docked to the docking station, do not undock it from the docking station before resuming normal operation. If you do undock it and then try to

Checking operational charging
To check whether the battery charges properly during operation, use a discharged battery pack or a battery pack that has less than 50% of the total power remaining when installed in the computer. Perform operational charging. If the battery status indicator or icon does not turn on, remove the battery pack and let it return to room temperature. Reinstall the battery pack. If the charge indicator or icon still does not turn on, replace the battery pack. If the charge indicator still does not turn on, replace the system board. Then reinstall the battery pack. If it is still not charged, go to the next section.

Checking the battery pack
Battery charging does not start until the Power Meter shows that less than 95% of the total power remains; under this condition the battery pack can charge to 100% of its capacity. This protects the battery pack from being overcharged or from having a shortened life. To check the status of your battery, move your cursor to the Power Meter icon in the icon tray of the Windows taskbar and wait for a moment (but do not click), and the percentage of battery power remaining is displayed. To get detailed information about the battery, double-click the Power Meter icon. Note: If the battery pack becomes hot, it may not be able to charge. Remove it from the computer and leave it at room temperature for a while. After it cools down, reinstall and recharge it. To check the battery pack, do the following: 1. Power off the computer. 2. Remove the battery pack and measure the voltage between battery terminals 1 (+) and 5 (-). See the following figure:

Terminal 1

Voltage (V dc) + 0 to + 12.6 Ground (-)
