Introduction
Important Service Information
Important
Diskette fixes are customer installable. The diskette
fixes are located on the PC Company Bulletin Board
Service (BBS). The direct phone line for modem con-
nection is 919-557-0001 or tieline 255-0001.
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 down-load information.
The Canadian BBS phone numbers are:
Montreal

Winnipeg 204-934-2735
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:
Ÿ
If you are instructed to replace a FRU and that
does not correct the problem, reinstall the original
FRU before you continue.
Ÿ
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.
Ÿ
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 symp-
toms 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 set-
tings. Note the current configuration settings (using
the View Configuration option) and verify that the set-
tings 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 dis-
played. 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 high-
lighted 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.

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 Notices (Multi-lingual
Translations)
In this manual, safety notices appear in English with a
page number reference to the appropriate multi-lingual,
translated safety notice found in this section.
The following safety notices are provided in English,
French, German, Italian, and Spanish languages.
Safety Notice 1
Before the computer is powered-on after FRU replace-
ment, make sure all screws, springs, or other small
parts are in place and are not left loose inside the
computer. Verify this by shaking the computer and lis-
tening for rattling sounds. Metallic parts or metal
flakes can cause electrical shorts.
Avant de remettre l'ordinateur sous tension après
remplacement d'une unité en clientèle, vérifiez que
tous les ressorts, vis et autres pièces sont bien en
place et bien fixées. Pour ce faire, secouez l'unité et
assurez-vous qu'aucun bruit suspect ne se produit.
Des pièces métalliques ou des copeaux de métal
pourraient causer un court-circuit.
Bevor nach einem FRU-Austausch der Computer
wieder angeschlossen wird, muß sichergestellt
werden, daß keine Schrauben, Federn oder andere
Kleinteile fehlen oder im Gehäuse vergessen wurden.
Der Computer muß geschüttelt und auf
Klappergeräusche geprüft werden. Metallteile oder
-splitter können Kurzschlüsse erzeugen.
Prima di accendere l'elaboratore dopo che é stata
effettuata la sostituzione di una FRU, accertarsi che
tutte le viti, le molle e tutte le altri parti di piccole
dimensioni siano nella corretta posizione e non siano
sparse all'interno dell'elaboratore. Verificare ciò
scuotendo l'elaboratore e prestando attenzione ad
eventuali rumori; eventuali parti o pezzetti metallici
possono provocare cortocircuiti pericolosi.
Antes de encender el sistema despues de sustituir
una FRU, compruebe que todos los tornillos, muelles
y demás piezas pequeñas se encuentran en su sitio y
no se encuentran sueltas dentro del sistema.
Compruébelo agitando el sistema y escuchando los
posibles ruidos que provocarían. Las piezas metálicas
pueden causar cortocircuitos eléctricos.

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:
Ÿ
Ÿ
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.
Ÿ
Ÿ
Ÿ
Place removed covers and other parts in a safe
place, away from all personnel, while you are ser-
vicing the machine.
Ÿ
Ÿ
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.
Ÿ
Ÿ
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.
Ÿ
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.
Ÿ
Ÿ
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 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.
Ÿ
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.
Ÿ
Ÿ
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
Ÿ
Ÿ
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.
12 ThinkPad 390E

Ÿ
Regularly inspect and maintain your electrical hand
tools for safe operational condition.
Ÿ
Ÿ
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.
Ÿ
Ÿ
Ÿ
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.)
Ÿ
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 identi-
fying potentially unsafe conditions on these products.
Each machine, as it was designed and built, had required
safety items installed to protect users and service per-
sonnel from injury. This guide addresses only those items.
However, good judgment should be used to identify poten-
tial 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:
Ÿ
Electrical hazards, especially primary power (primary
voltage on the frame can cause serious or fatal elec-
trical shock).
Ÿ
Ÿ
Explosive hazards, such as a damaged CRT face or
bulging capacitor
Mechanical hazards, such as loose or missing hard-
ware
Introduction 13

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 alter-
ations.
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 cir-
cuits (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 effec-
tive.
When handling ESD-sensitive parts:
Ÿ
Keep the parts in protective packages until they are
inserted into the product.
Ÿ
Ÿ
Avoid contact with other people.
Wear a grounded wrist strap against your skin to
eliminate static on your body.
Ÿ
Ÿ
Ÿ
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.
–
Grounding Requirements
Electrical grounding of the computer is required for oper-
ator safety and correct system function. Proper grounding
of the electrical outlet can be verified by a certified
electrician.

Maintenance Manual
Read This First
Before you go to the checkout guide, be sure to read this
section.
Important Notes
Ÿ
Ÿ
Ÿ
Ÿ
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 might be overwritten.
Ÿ
Ÿ
Replace FRUs only for the correct model. When
you replace a FRU, make sure 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 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. FRU
replacement should be considered only when a recur-
ring problem exists. If this is suspected, clear the
error log and run the test again. Do not replace any
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 the
display, and beep symptoms
6. Procedure index and page number in which the failing
FRU was detected

Power System Checkout
To verify the symptom of the problem power on the com-
puter using each of the following power sources:
1. Remove the battery ASM.
2. Connect the AC Adapter and check that power is sup-
plied.
3. Disconnect the AC Adapter and install the charged
battery ASM; then check that power is supplied by the
battery ASM.
If you suspect a power problem, refer to the appropriate
power supply check listed below:
Ÿ
Ÿ
Ÿ
“Checking the AC Adapter”
“Checking the Operational Charging” on page 34
“Checking the Battery ASM” on page 34
Checking the AC Adapter: You are here
because the computer fails only when the AC Adapter is
used:
Ÿ
If the power problem occurs only when the ThinkPad
Port Replicator with Advanced Etherjet Feature.
Ÿ
If the power-on indicator does not turn on, check the
power cord of the AC Adapter for correct continuity
and installation.
Ÿ
If the operational charge does not work, go to
“Checking the Operational Charging” on page 34.
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.
Pin
1
Voltage (V dc)
+15.5 to +17.0
Ground
2
If the voltage is not correct, replace the AC Adapter.
If the voltage is within the range, do the following:
Ÿ
Ÿ
Ÿ
Replace the DC-DC & BATT board.
Replace the system board.
If the problem is not corrected, go to “Undetermined
Problems” on page 47
Note: An audible noise from the AC Adapter does not
always indicate a defective adapter.

Checking the 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
does not turn on, remove the Battery ASM and let it return
to room temperature. Reinstall the Battery ASM.
If the charge indicator 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 ASM
charging will not start until the Fuel-Gauge shows that less
than 95% of the total power remains; with this condition,
the Battery ASM can charge to 100% of its capacity. This
protects the Battery ASM from being overcharged or
having a shortened life.
Do the following:
1. Power off the computer.
2. Remove the Battery ASM and measure the voltage
between battery terminals 1(+) and 7(-). See the fol-
lowing figure:
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 ter-
minals 5 and 7. The resistance must be 390 ohm
(Li-Ion) or 4 to 3K ohm. 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.

TrackPoint Checkout
If the external mouse is connected, the TrackPoint does
not work. In this case, please detach the external mouse to
check the TrackPoint.
If this does not correct the TrackPoint problem, continue
with the following.
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 ina short period of time.
If a click button problem or pointing stick problem occurs,
do the following:
1. Boot from and start PC Doctor. (See “PC Doctor
System Diagnostics” on page 51 for details.)
2. Select Interactive Tests.
3. Select Mouse.
4. Follow the instructions in the message window.
If either the pointing stick or the click button does not work,
do the following actions one a time to correct the problem.
Do not replace a non-defective FRU.
1. Reseat the keyboard cables.
2. Replace the keyboard.
3. Replace the system board.

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 be considered
only when a recurring problem exists.
When analyzing an intermittent problem, do the following:
1. Run the advanced diagnostic test for the system
board in loop mode at least 10 times.
2. If no error is detected, do not replace any FRUs.
46 ThinkPad 390E
Download from Www.Somanuals.com. All Manuals Search And Download.
3. If any error is detected, replace the FRU shown by
the FRU code.. Rerun the test to verify that no more
errors exist.
Undetermined Problems
You are here because 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 these procedures to
isolate the failing FRU (do not isolate nondefective FRUs).
Verify that the power supply being used at the time of the
failure is operating correctly. (See “Power System
Checkout” on page 33).
1. Power off the computer.
2. Visually check them for damage. If any problems are
found, replace the FRU.
3. Remove or disconnect all of the following devices:
a. Non-IBM devices
b. Devices attached to the ThinkPad Port
Replicator with Advanced Etherjet Feature
c. Printer, mouse, and other external devices
d. Battery ASM
e. Hard disk drive
f. DIMM
g. CD-ROM and Diskette Drive (FDD ASM) in the
Combobay (UltraBay FX)
h. PC Cards (PCMCIA)
4. Power on the computer.
5. Determine if the problem has changed.
6. If the problem does not recur, 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.
a. System board
b. LCD panel ASM
c. CPU card

Setting the LCD Panel ID
There is an EEPROM in the inverter which stores its sup-
ported LCD type ID code. If you replace a LCD with one of
a different brand or use a new inverter, the ID information
in the inverter EEPROM should be updated.
Follow the steps below to set the LCD Panel ID:
1. Boot from the Utility Program Diskette.
2. Select LCD Panel ID Utility from PC DOS 7.0
Startup Menu.
3. Follow the instructions on the screen to read the
current or to set a new LCD Panel ID code.
Note: When you set a new LCD Panel ID and the
new LCD is not yet enabled (to function),
connect an external CRT to see the program
execution process.
Attention: Make sure the new ID code you choose
corresponds to the LCD brand and type. If you write a
wrong ID into the inverter, just reboot and re-execute
the program and input the correct ID code.
4. Restart the computer — the new LCD should work
normally.
Note: If the LCD cannot display after changing the ID
code, make sure you write the correct ID code or
try reconnecting the LCD FPC cable connectors.
Setting the Thermal Sensor
The system is equipped with sensors to protect against
system overheating. By setting the system and processor
thermal thresholds, the system can turn on the cooling Fan
ASM or shut down automatically when the temperature
reaches the defined threshold parameters.
System experiencing frequent auto sensor shutdown may
need to reset the thermal sensor threshold and execute
the Fan ASM test to ensure the normal operation of the
cooling Fan ASM (refer to “Fan ASM Checkout” on
page 29).
Follow the steps below to set the thermal threshold:
1. Boot from the Utility Program Diskette.
2. Select Thermal Sensor Utility from PC DOS 7.0
Startup menu, then press F4.

Writing the RFID Data
The EEPROM on the system board contains the system
unit serial number and the system board serial number.
When you replace the system board, restore the system
unit serial number using the RFID Utility in the ThinkPad
CE Utility Diskette. The serial number label is attached to
the computer.
This utility allows you to
Ÿ
Ÿ
Ÿ
add S/N data to the EEPROM (option 1)
read S/N data from the EEPROM (option 2)
delete S/N data from the EEPROM (option 3)
Follow the instructions on the screen.
Flash UUID
The EEPROM on the system board contains the Universal
Unique ID (UUID) — that is, for Microsoft or Internet use.
When you replace the system board using the Flash UUID
Utility in the ThinkPad CE Utility Diskette. The UUID utility
will automatically assign the UUID via Windows.

LCD FRU Replacement Notice: The TFT LCD
for the notebook computer contains over 2,359,296 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:
Ÿ
SVGA (12.1"): 5 or more bright dots, 5 or more dark
dots, or a total of 9 or more bright and dark dots
Ÿ
XGA (13.3"/14.1"): 8 or more bright dots, 8 or more
dark dots, or a total of 9 or more bright and dark dots
Replacing the system Board: When you
replace the system board, restore the system unit serial
number using the RFID Utility and reassign the UUID using
the Flash UUID Utility in the ThinkPad 390E CE Utility
Diskette. See “Writing the RFID Data” on page 49 and
“Flash UUID” on page 49 respectively.
Note: Do not power off the computer while restoring the
RFID.
