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 ser- vicing. Running Automatic Configuration may alter those settings. Note the current configuration settings (using the
2 ThinkPad i Series 1400/1500 HMM
all-guides.com
Page 12
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 dis- played 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 ser- vicing 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 conduc-
tors.
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 elec- trical currents. Many customers have, near their equip- ment, 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 elec- trical 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
12 ThinkPad i Series 1400/1500 HMM
all-guides.com
Page 22
– 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 accesso- ries 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. Regu- larly 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 13
Page 23
– 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 your-
self.
– 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 judg- ment 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. Con- sider these conditions and the safety hazards they present:
Electrical hazards, especially primary power (primary
voltage on the frame can cause serious or fatal elec- trical shock).
Explosive hazards, such as a damaged CRT face or
bulging capacitor.
Mechanical hazards, such as loose or missing hard-
ware.
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 conti- nuity 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
Page 24
6. Check inside the unit for any obvious unsafe condi- tions, 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 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.

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 entire FRU service procedures before
replacing any FRUs.
Use new nylon-coated screws when you replace
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.
Replace FRUs only for the correct model. When
you replace a FRU, make sure that the model of the machine and FRU part number are correct by refer- ring to the FRU parts list.
A FRU 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 recur- ring 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.
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
2. Date of service
3. Date when part failed
4. Date of purchase
5. Failure symptoms, error codes appearing on display, and beep symptoms
6. Procedure index and page number in which failing FRU was detected

To verify the symptom of the power problem on the com- puter, 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 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:
1
2
30
ThinkPad i Series 1400/1500 HMM
Page 40
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 38.
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 or does not show orange color, remove the Battery ASM and let it return to room temper- ature. Reinstall the Battery ASM. If the charge indicator or icon still does not turn on or still does not show orange color, 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: After the battery is
fully charged, charger can not charge battery until the Fuel Gauge shows that less than 95% of 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.
2. Remove the battery pack and measure the voltage between battery terminals 1 (+) and 7 (-). See the fol- lowing figure.

3. First, discharge the battery, until the voltage is less than 10.8V (LiIon) or 9.6V (NiMH). Then, charge the battery for 30 minutes. Now, check the voltage. If the voltage is still less than 10.8V (Li-Ion) or 9.6V (NiMH), replace the battery.
4. If the voltage is more than 10.8V (LiIon) or 9.6V (NiMH), measure the resistance between battery ter- minals 5 and 7. The resistance must be 390Ω (Li-Ion) or 10KΩ (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.

Symptom-to-FRU Index
The Symptom-to-FRU Index lists the symptoms and errors and the possible causes. The most likely cause is listed first.
Note: Perform the FRU replacement or actions in the
sequence shown in the FRU/Action columns. If a FRU does not solve the problem, put the original part back in the computer. Do not replace a non- defective FRU.
This index can also be used to help you decide which FRUs should be available when servicing a computer.
Numeric error codes show the errors detected in POST or system operation (runtime). In the following error codes, X can be any number.
If no codes are available, use narrative symptoms. If the symptom, is not listed, go to “Undetermined
Problems” on page 38. Note: For any IBM device not supported by the diagnostic
codes in this ThinkPad computer, see the manual for that device.

LCD-Related Symptoms
LCD FRU Replacement Notice
The TFT LCD for the computer contains many thin-film transistors (TFTs). A small number of missing, discol- ored, or lighted dots (on all the time) is characteristic of TFT LCD technology, but excessive pixel problems can cause viewing concerns. The LCD should be replaced if the number of missing, discolored, or lighted dots in any background is:
SVGA (12.1"): 5 or more bright dots, 5 or more
dark dots, or a total of 9 or more bright and dark dots.
XGA (14.1"/15.0"): 8 or more bright dots, 8 or
more dark dots, or a total of 9 or more bright and dark dots.

Intermittent Problems
Intermittent system hang problems can be caused by a variety of reasons that have nothing to do with a hardware defect, such as cosmic radiation, electronic discharge, or software errors. FRU replacement should only be consid- ered when a recurring problem exists.
When analyzing the intermittent problem, do the following:
1. Run the diagnostic test for the system board at least 10 times.
2. If no error is detected, do not replace any FRUs.
3. If any error is detected, replace the FRU. Rerun the test to verify that there are no more errors.
Undetermined Problems
The diagnostic tests did not identify which adapter or device failed, which installed devices are incorrect, whether a short circuit is suspected, or whether the system is inop- erative. Follow the procedures below to isolate the failing FRU.
Verify that the power supply being used at the time of the failure is operating correctly.
1. Power off the computer.
38 ThinkPad i Series 1400/1500 HMM
Page 48
2. Check the cables, wires, and connectors for short cir- cuits and open circuits. Visually check them for damage. If any problems are found, replace the FRU.
3. Remove or disconnect all of the following devices: Non-IBM devices
Printer, external mouse & keyboard, and other
external devices
Battery pack
Hard disk drive Diskette drive/CD-ROM drive PC Card (PCMCIA)
4. Power on the computer.
5. Determine if the problem has changed.
6. If the problem does not occur again, reconnect the removed devices one at a time until you find the failing FRU.
7. If the problem remains, replace the following FRUs one at a time. Do not replace a non-defective FRU.

TrackPont or Pointing device
If the TrackPoint does not work, see if
an external PS/2 mouse is connected
to the mouse/keyboard connector and
remove it. The TrackPoint is automat-
ically 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 move-
ment can occur when a slight, steady
pressure is applied to the TrackPoint
pointer. This symptom is not a hard-
ware problem. No service actions are
necessary if the pointer movement
stops in a short period of time.
If this does not correct the TrackPoint
problem, continue with the following:
