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 settings. Note the current configuration settings (using the

2

ThinkPad i Series 1400/1500 HMM

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.

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. 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. 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 ThinkPad i Series 1400/1500

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: 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.

14

ThinkPad i Series 1400/1500 HMM

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. 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.

Power systems checkout
To verify the symptom of the power problem on the computer, do the following: 1. Power off the computer. 2. Remove the battery pack. 3. Connect the AC Adapter. 4. Check that power is supplied when you power on the computer. 5. Power off the computer. 6. Disconnect the AC Adapter and install the charged battery pack. 7. Check that power is supplied by the battery pack when you power on the computer. If you suspect a power problem, refer the the appropriate power supply check listed below: "Checking the AC Adapter" "Checking operational charging" on page 31 "Checking the Battery ASM" on page 31

Checking the AC Adapter:

You care here because the computer fails only when the AC Adapter is used: If the power-on indicator does not turn on, check the power cord of the AC Adapter for correct continuity and installation. If the operational charge does not work, go to "Checking operational charging" on page 31.

Unplug the AC Adapter cable from the computer and measure the output voltage at the plug of the AC Adapter cable. See the following figure:

30

ThinkPad i Series 1400/1500 HMM

Pin 1 2

Voltage (V dc) 15.5 17.0 Ground

If the voltage is not correct, replace the AC Adapter. If the voltage is within the range, do the following: Replace the DC-DC & BATT board. Replace the system board. If the problems still persist, go to "Undetermined Problems" on page 43. Note: An audible noise from the AC Adapter does not always indicate a defect.

Checking operational charging:

To check operational charging, use a discharged battery pack (Battery ASM) or a Battery ASM 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 ASM and let it return to room temperature. Reinstall the Battery ASM. If the charge indicator or icon still does not turn on, replace the Battery ASM. If the charge indicator still does not turn on, replace the DC-DC & BATT board, then the system board. Then reinstall the Battery ASM. If the reinstalled Battery ASM is not charged, go to the next section.

Checking the Battery ASM:

Battery charging does not start until the Fuel-Gauge shows that less than 95% of the total power remains; with this condition the battery pack can charge to 100% of its capacity. This protects the Battery ASM from being overcharged or from having a shortened life. Note: The Battery ASM might not be able to charged when it is hot. In that case, remove it from the computer and leave it at room temperature for a while. After it cools down, reinstall it and recharge it.

Do the following: 1. Power off the computer.

ThinkPad i Series 1400/1500

31

2. Remove the battery pack and measure the voltage between battery terminals 1 (+) and 7 (-). See the following figure.

Terminal 1 2 3 4 5 6 7

Signal / Voltage (V dc) Ground BT-SENSE BT-SCLK BT-SDATA BT-TH BT+SENSE BT+

Note: Signal lines, not used in these steps, are used for communications between the system and the battery. 3. If the voltage is less than 10.6V (Li-Ion) or 9.6V (NiMH), the Battery ASM has been discharged, recharge the Battery ASM. If the voltage is still less than 10.6V (Li-Ion) or 9.6V (NiMH), replace the battery. 4. If the voltage is more than 10.6V (Li-Ion) or 9.6V (NiMH), measure the resistance between battery terminals 5 and 7. The resistance must be 390 (Li-Ion) or 10K (NiMH). If the resistance is not correct, replace the Battery ASM. If the resistance is correct, replace the DC-DC & BATT board, then the system board.

The TrackPoint is automatically disabled if an external PS/2 mouse is attached. Check also if the TrackPoint driver is correctly installed by accessing Windows Device Manager via the System icon in the Control Panel. After you use the TrackPoint, the pointer drifts on the screen for a short time. This self-acting pointer movement can occur whne a slight, steady pressure is applied to the TrackPoint pointer. This symptom is not a hardware problem. No service actions are necessary if the pointer movement stops in a short period of time.
