FRU Replacement Strategy
Before Replacing Parts Ensure that all diskette fixes are installed prior to replacing any FRUs listed in this manual. Use the following strategy to prevent unnecessary FRU replacement and service expense: If you are instructed to replace a FRU and that does not correct the problem, reinstall the original FRU before you continue. 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 the first board that you replaced does not correct the problem, reinstall the original board, then replace the other (processor or system) board. If an adapter or device consists of more than one FRU, an error code may be caused by any of the FRUs. 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: A customized setup configuration (other than default settings) may exist on the computer you are servicing. Running Automatic Configuration may alter those Introduction

settings. Note the current configuration settings (using the View Configuration option) and verify that the settings are in place when service is complete.
Hard Disk Drive Replacement Strategy:
Always try to run a low-level format before replacing a hard disk drive. Attention: The drive startup sequence in the computer you are servicing might have been changed. Be extremely careful during write operations such as copying, saving, or formatting. Data or programs can be over-written if you select an incorrect drive.
How to Use Error Messages
Use the error codes displayed on the screen to diagnose failures. If more than one error code is displayed, begin the diagnosis with the first error code. The cause of the first error code can result in false error codes being displayed. If no error code is displayed, see if the error symptom is listed in the Symptom-to-FRU Index for the computer you are servicing.
How to Read POST Error Messages
POST error messages are displayed on the screen as three, four, five, or eight digits. The error messages that can be displayed as shorter POST messages are highlighted in this index. Some digits will represent different information for SCSI errors versus non-SCSI errors. The following example shows which digits display the shorter POST error messages and also defines the SCSI information in an eight-digit error message. POST All SCSI devices are set to a different SCSI ID. Duplicate SCSI ID settings can generate a false error message. Use the SCSI ID to determine whether the error message is coming from an internal or an external device.

Safety Information
The following section contains 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: Observe good housekeeping in the area of the machines during and after maintenance. 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 objects that weigh more than 16 kg (35 lb) or objects that you think are too heavy for you. Do not perform any action that causes hazards to the customer, or that makes the equipment unsafe. Before you start the machine, ensure that other service representatives and the customer's personnel are not in a hazardous position. Place removed covers and other parts in a safe place, away from all personnel, while you are servicing the machine. Keep your tool case away from walk areas so that other people will not trip over it. Do not wear loose clothing that can be trapped in the moving parts of a machine. Ensure that your sleeves are fastened or rolled up above your elbows. If your hair is long, fasten it. 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. Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your clothing. Attention: Metal objects are good electrical conductors. 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. After service, reinstall all safety shields, guards, labels, and ground wires. Replace any safety device that is worn or defective. Introduction

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. 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. Do not work alone under hazardous conditions or near equipment that has hazardous voltages. Disconnect all power before: Performing a mechanical inspection Working near power supplies Removing or installing main units
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. 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: There must be a complete circuit to cause electrical shock. By observing the above rule, you may prevent a current from passing through your body. When using testers, set the controls correctly and use the approved probe leads and accessories for that tester.
12
ThinkPad i Series 1400 HMM
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. Regularly inspect and maintain your electrical hand tools for safe operational condition. Do not use worn or broken tools and testers. Never assume that power has been disconnected from a circuit. First, check that it has been powered-off. 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. 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. 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.) 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 intent of this inspection guide is to assist you in identifying potentially unsafe conditions on these products. Each machine, as it was designed and built, had required safety items installed to protect users and service personnel from injury. This guide addresses only those items. However, good judgment should be used to identify potential safety hazards due to attachment of non-IBM features or options not covered by this inspection guide. 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: Introduction
13
Electrical hazards, especially primary power (primary voltage on the frame can cause serious or fatal electrical shock). Explosive hazards, such as a damaged CRT face or bulging capacitor. Mechanical hazards, such as loose or missing hardware. The guide consists of a series of steps presented in a checklist. 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 appropriate type as specified in the parts listings. 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 Electrostatic Discharge-Sensitive Devices
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 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.
14
ThinkPad i Series 1400 HMM
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: Keep the parts in protective packages until they are inserted into the product. Avoid contact with other people. Wear a grounded wrist strap against your skin to eliminate static on your body. Prevent the part from touching your clothing. Most clothing is insulative and retains a charge even when you are wearing a wrist strap. 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. 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 batteryoperated 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.
Grounding Requirements
Electrical grounding of the computer is required for operator safety and correct system function. Proper grounding of the electrical outlet can be verified by a certified electrician.

Read This First
Before you go to the check procedures, be sure to read this section. Important Notes Only certified trained personnel should service the computer. Read the FRU service procedures before replacing any FRUs. Be extremely careful during write operations such as copying, saving, or formatting. Drives in the computer that you are servicing might have been rearranged or the drive startup sequence might have been altered. If you select an incorrect drive, data or programs could be overwritten. Ensure that you replace FRUs with the appropriate model. When you replace the FRU, make sure that the model of the machine and FRU part number are correct by referring to the part list. FRUs should not be replaced because of a single, unreproducible failure. Single failure can occur for a variety of reasons that have nothing to do with a hardware defect, such as: cosmic radiation, electrostatic discharge, or software error. FRU replacement should be considered only when a recurring problem exists. In this case, clear the error log and run the test again. Do not replace FRUs if log errors do not reappear. Be careful not to replace a non-defective FRU.
How to Use Error Messages
Use the error codes displayed on the screen to diagnose failures. If more than one error code is displayed, begin the diagnosis with the first error code. The cause of the first error code can result in the other false error codes being displayed.
How to Diagnose Mulitple FRUs
If the adapter or device has more than one FRU, the error code could be caused by either FRU. Before replacing multiple FRUs, try removing or exhanging each FRU one by one in the designated sequence, to see if the symptoms change.
What to Do First
The servicer must include the following in the parts exchange form or parts return form that is attached to the returned FRU: 1. Name and phone number of servicer.

TrackPoint IV Check
The TrackPoint does automatic compensations to adjust the pointer sensor. During this process, the pointer moves on the screen automatically for a short time. This selfacting pointer movement can occur when a slight, steady pressure is applied to the TrackPoint pointer while the computer is powered on or while the system is running, or when readjustment is required because the temperature has exceeded its normal temperature range. This symptom does not indicate a hardware problem. No service actions are necessary if the pointer movement stops in a short period of time. If a click button problem or pointing stick problem occurs, do the following: 1. Boot from the diagnostics diskette and start the PQA program (please refer to "Running the PQA Diagnostics Program" on page 49).
