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.

Safety Notice 7

Though main batteries have low voltage, a shorted or
grounded battery can produce enough current to burn
combustible materials or personnel.

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 Kurzschluβ oder Erdung
genug Strom abgeben, um brennbare Materialien zu

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.

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.

ThinkPad i Series 1400/1500

Do not attempt to lift any

11

 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 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 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

12 ThinkPad i Series 1400/1500 HMM

– 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 13

– 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 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 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 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.

ThinkPad i Series 1400/1500

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.

LCD replacement notice

The TFT LCD for the computer contains many thin-film
transistors (TFTs). A small number of missing, discolored,
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.

Screw notices

This computer uses special nylon-coated screws with the
following characteristics:

 They maintain tight connections.
 They do not easily come loose, even with shock or

vibration.

 They need additional force to tighten.
 They should be used only once.

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 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:

2

1

ThinkPad i Series 1400/1500 HMM

30

Pin Voltage (V dc)

1 15.5V — 17.0V
2 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 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 temper­ature. 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 fol­lowing figure.

4 BT-SDATA
5 BT-TH
6 BT+SENSE
7 BT+

Note: Signal lines, not used in these steps, are used

for communications between the system and
the battery.

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 ter­minals 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 non­defective 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.

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 consid­ered 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 inop­erative. 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

2. Check the cables, wires, and connectors for short cir­cuits 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.

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 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 when 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.

If this does not correct the TrackPoint
