General safety
Follow these rules to ensure general safety:
v Observe good housekeeping in the area of the machines during and after
maintenance.
v When lifting any heavy object:
1. Make sure that 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 object that
weighs more than 16 kg (35 lb) or that you think is too heavy for you.
v Do not perform any action that causes hazards to the customer, or that makes
the equipment unsafe.
v Before you start the machine, make sure that other service technicians and the
customer’s personnel are not in a hazardous position.
v Place removed covers and other parts in a safe place, away from all personnel,
while you are servicing the machine.
v Keep your toolcase away from walk areas so that other people will not trip over
it.
v Do not wear loose clothing that can be trapped in the moving parts of a
machine. Make sure that your sleeves are fastened or rolled up above your
elbows. If your hair is long, fasten it.
v Insert the ends of your necktie or scarf inside clothing or fasten it with a
nonconductive clip, about 8 centimeters (3 inches) from the end.
v Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your
clothing.
Attention: Metal objects are good electrical conductors.
v 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.
v After service, reinstall all safety shields, guards, labels, and ground wires.
Replace any safety device that is worn or defective.
v Reinstall all covers correctly before returning the machine to the customer.
v Fan louvers on the machine help to prevent overheating of internal components.
Do not obstruct fan louvers or cover them with labels or stickers.

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.
v 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.
v Do not work alone under hazardous conditions or near equipment that has
hazardous voltages.
v Disconnect all power before:
– Performing a mechanical inspection
– Working near power supplies
– Removing or installing main units
v 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.
v 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: An electrical shock can occur only when there is a complete
circuit. 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;
Instructions for these precautions are in the safety sections of maintenance
information. Use extreme care when measuring high voltages.
v Regularly inspect and maintain your electrical hand tools for safe operational
condition.
v Do not use worn or broken tools and testers.
v Never assume that power has been disconnected from a circuit. First, check that it
has been powered off.
v 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.
Safety information
3
v 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.
v 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
– Similar units to listed above
This practice ensures correct grounding of the units.
v 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 purpose of this inspection guide is to assist you in identifying potentially
unsafe conditions. As each machine was designed and built, required safety items
were installed to protect users and service technicians from injury. This guide
addresses only those items. You should use good judgment to identify potential
safety hazards due to attachment of non-ThinkPad 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:
v Electrical hazards, especially primary power (primary voltage on the frame can
cause serious or fatal electrical shock)
v Explosive hazards, such as a damaged CRT face or a bulging capacitor
v Mechanical hazards, such as loose or missing hardware
To determine whether there are any potentially unsafe conditions, use the
following checklist at the beginning of every service task. 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 the frame ground.
b. The power cord should be the type specified in the parts list.
c. Insulation must not be frayed or worn.
4. Check for cracked or bulging batteries.
5. Remove the cover.
6. Check for any obvious non-ThinkPad alterations. Use good judgment as to the
safety of any non-ThinkPad alterations.
7. 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.
8. Check for worn, frayed, or pinched cables.
9. Check that the power-supply cover fasteners (screws or rivets) have not been
removed or tampered with.
Safety information

Handling devices that are sensitive to electrostatic discharge
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:
v Keep the parts in protective packages until they are inserted into the product.
v Avoid contact with other people.
v Wear a grounded wrist strap against your skin to eliminate static on your body.
v Prevent the part from touching your clothing. Most clothing is insulative and
retains a charge even when you are wearing a wrist strap.
v Use a grounded work mat to provide a static-free work surface. The mat is
especially useful when handling ESD-sensitive devices.
v 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 to guard against ESD damage is desirable but not
necessary.
– Attach the ESD ground clip to any frame ground, ground braid, or green-wire
ground.
– When working on a double-insulated or battery-operated system, use an ESD
common ground or reference point. 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.

system board before completing the service action.
To download software fixes, drivers, and BIOS, do as follows:
2. Enter the product number of the computer or press Auto-detect button on the
screen.
3. Select Downloads and drivers.
4. Follow the directions on the screen and install the necessary software.

Use the following strategy to prevent unnecessary expense for replacing and
servicing FRUs:
v If you are instructed to replace a FRU but the replacement does not correct the
problem, reinstall the original FRU before you continue.
v 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
replacing one of them does not correct the problem, reinstall that board, and
then replace the other one.
v If an adapter or a device consists of more than one FRU, any of the FRUs may
be the cause of the error. 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: The setup configuration on the computer you are servicing may have
been customized. Running Automatic Configuration may alter the settings. Note
the current configuration settings (using the View Configuration option); then,
when service has been completed, verify that those settings remain in effect.
Strategy for replacing a hard disk drive
Always try to run a low-level format before replacing a hard disk drive. This will
cause all customer data on the hard disk to be lost. Be sure that the customer has a
current backup of the data before doing this task.
Attention: The drive startup sequence in the computer you are servicing may
have been changed. Be extremely careful during write operations such as copying,
saving, or formatting. If you select an incorrect drive, data or programs can be
overwritten.
Important notice for replacing a system board
Some components mounted on a system board are very sensitive. Improper
handling of a system board can cause damage to those components, and may
cause a system malfunction.
Attention: When handling a system board:
v Do not drop a system board or apply any excessive force to it.
v Avoid rough handling of any kind.
v Avoid bending a system board and hard pushing to prevent cracking at each
BGA (Ball Grid Array) chipset.
How to use error message
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. Whatever
causes the first error code may also cause false error codes. If no error code is
displayed, see whether the error symptom is listed in the Symptom-to-FRU Index
for the computer you are servicing.

Strategy for replacing FRUs for CTO, CMV, and GAV
Product definition
Dynamic Configure To Order (CTO)
This provides the ability for a customer to configure an IBM® or a Lenovo solution
from an eSite, and have this configuration sent to fulfillment, where it is built and
shipped directly to the customer. The machine label, Product Entitlement
Warehouse (PEW), eSupport, and the HMM will load these products as the 4-digit
MT and 3-digit model, where model = “CTO” (Example: 1829-CTO).
Custom Model Variant (CMV)
This is a unique configuration that has been negotiated between IBM or Lenovo
and the customer. A unique 4-digit MT and 3-digit model is provided to the
customer to place orders (Example: 1829-W15). A CMV is a special bid offering.
Therefore, it is NOT generally announced.
v The MTM portion of the machine label is the 4-digit MT and 3-digit model,
where model = “CTO” (Example: 1829-CTO). The PRODUCT ID portion of the
machine label is the 4-digit MT and 3-digit CMV model (Example: 1829-W15).
v The PEW record is the 4-digit MT and 3-digit model, where model = “CTO”
(Example: 1829-CTO).
v eSupport will show both the CTO and CMV machine type models (Example:
1829-CTO and 1829-W15 will be found on the eSupport site.)
v The HMM will have the 4-digit MT and 3-digit CTO model only (Example:
1829-CTO). Again, CMVs are custom models and are not found in the HMM.
General Announce Variant (GAV)
This is a standard model (fixed configuration). GAVs are announced and offered to
all customers. The MTM portion of the machine label is a 4-digit MT and 3-digit
model, where model = a “fixed part number”, not “CTO” (Example: 1829-F1U).
Also, PEW, eSupport, and the HMM will list these products under the same fixed
model number.
FRU identification for CTO, CMV, and GAV products
There are three information resources to identify which FRUs are used to support
CTO, CMV, and GAV products. These sources are PEW, eSupport, and the HMM.
Using PEW
v PEW is the primary source for identifying FRU part numbers and FRU
descriptions for the key commodities for CTO, CMV and GAV products at a MT
- serial number level. An example of key commodities are hard disk drives,
system boards, microprocessors, Liquid Crystal Displays (LCDs), and memory.
v Remember, all CTO and CMV products are loaded in PEW under the 4-digit MT
and 3-digit model, where model = “CTO” (Example: 1829-CTO). GAVs are
loaded in PEW under the 4-digit MT and 3-digit model, where model = a “fixed
part number”, not “CTO” (Example: 1829-F1U).
v PEW can be accessed at the following Web site:
Select Warranty lookup. Input the MT and the Serial number and the list of key
commodities will be returned in the PEW record under COMPONENT
INFORMATION.
Important service information 41
v Business Partners using Eclaim will access PEW when performing Entitlement
Lookup. Business Partners will enter Loc ID, MT and Serial, and the key
commodities will be returned in the Eclaim record under SYSTEM DETAILS.
v Authorized IBM Business Partners can access Eclaim at the following Web site:
Using eSupport
For Key Commodities (Examples - hard disk drive, system board,
microprocessor, LCD, and memory)
v eSupport can be used to view the list of key commodities built in a particular
machine serial (this is the same record found in PEW).
v To view the key commodities, click on PARTS INFORMATION, then PARTS
LOOKUP. Type in the model type and serial number. The key commodities will
be returned in the eSupport record under PARTS SHIPPED WITH YOUR
SYSTEM.
For the Remaining FRUs (the complete list of FRUs at the MT Model level)
v eSupport can be used to view the complete list of FRUs for a machine type and
model.
v To view the complete list of FRUs, type in the machine type and model
(Example: 1829-CTO) under QUICK PATH. Under “View by Document Type”
select PARTS INFORMATION. Under “Filter by Category” select SERVICE
PARTS. Under “Parts Information by Date” select SYSTEM SERVICE PARTS. The
list of service parts by description, with applicable machine type model and FRU
will be displayed.
Using the HMM
For Key Commodities (Examples - hard disk drive, system board,
microprocessor, LCD, and memory)
Use the HMM as a back-up to PEW and eSupport to view the complete list of
FRUs at the MT Model level.

v When you replace FRUs, use new nylon-coated screws.
v Be extremely careful during such write operations as copying, saving, or
formatting. Drives in the computer that you are servicing sequence might
have been altered. If you select an incorrect drive, data or programs might be
overwritten.
v Replace a FRU only with another FRU of the correct model. When you
replace a FRU, make sure that the model of the machine and the FRU part
number are correct by referring to the FRU parts list.
v 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. Consider replacing a FRU only when a problem recurs. If you
suspect that a FRU is defective, clear the error log and run the test again. If
the error does not recur, do not replace the FRU.
v Be careful not to replace a nondefective FRU.

v Replace the system board.
Note: Noise from the AC adapter does not always indicate a defect.
Checking operational charging
To check whether the battery charges properly during operation, use a discharged
battery pack or a battery pack that has less than 50% of the total power remaining
when installed in the computer.
52 ThinkPad X301 Hardware Maintenance Manual
Perform operational charging. If the battery status indicator or icon does not turn
on, remove the battery pack and let it return to room temperature. Reinstall the
battery pack. If the charge indicator or icon still does not turn on, replace the
battery pack.
If the charge indicator still does not turn on, replace the system board. Then
reinstall the battery pack. If it is still not charged, go to the next section.
Checking the battery pack
Battery charging does not start until the Power Manager Battery Gauge shows that
less than 96% of the total power remains; under this condition the battery pack can
charge to 100% of its capacity. This protects the battery pack from being
overcharged or from having a shortened life.
To check your battery, move your cursor to the Power Manager Battery Gauge icon
in the icon tray of the Windows taskbar and wait for a moment (but do not click),
and the percentage of battery power remaining is displayed. To get detailed
information about the battery, double-click the Power Manager Battery Gauge icon.
Note: If the battery pack becomes hot, it may not be able to charge. Remove it
from the computer and leave it at room temperature for a while. After it cools
down, reinstall and recharge it.
To check the battery pack, 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:

Passwords
As many as three passwords may be needed for any ThinkPad Notebook: the
power-on password (POP), the hard-disk password (HDP), and the supervisor
password (SVP).
If any of these passwords has been set, a prompt for it appears on the screen
whenever the computer is turned on. The computer does not start until the
password is entered.
Exception: If only an SVP is installed, the password prompt does not appear when
the operating system is booted.
Power-on password
A power-on password (POP) protects the system from being powered on by an
unauthorized person. The password must be entered before an operating system
Hard-disk password
There are two hard-disk passwords (HDPs):
v User HDP—for the user
v Master HDP—for the system administrator, who can use it to get access to the
hard disk even if the user has changed the user HDP
Related service information 57
Note: There are two modes for the HDP: User only and Master + User. The
Master + User mode requires two HDPs; the system administrator enters both in
the same operation. The system administrator then provides the user HDP to the
system user.
Attention: If the user HDP has been forgotten, check whether a master HDP has
been set. If it has, it can be used for access to the hard disk drive. If no master
HDP is available, neither Lenovo nor Lenovo authorized service technicians
provide any services to reset either the user or the master HDP, or to recover data
from the hard disk drive. The hard disk drive can be replaced for a scheduled fee.
Supervisor password
A supervisor password (SVP) protects the system information stored in the BIOS
Setup Utility. The user must enter the SVP in order to get access to the BIOS Setup
Utility and change the system configuration.
Attention: If the SVP has been forgotten and cannot be made available to the
service technician, there is no service procedure to reset the password. The system
board must be replaced for a scheduled fee.
How to remove the power-on password
To remove a POP that you have forgotten, do the following:
(A) If no SVP has been set:
1. Turn off the computer.
2. Remove the battery pack.
For how to remove the battery pack, see “1010 Battery pack” on page 83.
3. Remove the backup battery.
4. Turn on the computer and wait until the POST ends.
After the POST ends, the password prompt does not appear. The POP has been
removed.
5. Reinstall the backup battery and the battery pack.

Power management
To reduce power consumption, the computer has three power management modes:
screen blank, sleep (standby in Windows XP), and hibernation.
Screen blank mode
If the time set on the “Turn off monitor” timer in the operating system expires, the
LCD backlight turns off.
To put the computer into screen blank mode, do as follows:
1. Press Fn+F3. A panel for selecting a power plan (in Windows XP, power
scheme) appears.
2. Select Power off display (keep current power plan) (in Windows XP, keep
current power scheme).
You can also put the computer into screen blank mode, press ThinkVantage button
and use the ThinkVantage Productivity Center.
Note: If the computer is a Windows 7 model, it does not support ThinkVantage
Productivity Center.
To end screen blank mode and resume normal operation, press any key.
Sleep (Standby) mode
When the computer enters sleep (standby) mode, the following events occur in
addition to what occurs in screen blank mode:
v The LCD is powered off.
v The hard disk drive is powered off.
v The CPU stops.
To enter sleep (standby) mode, press Fn+F4.
Note: You can change the action of the Fn+F4 key combination by changing the
settings in Power Manager.

LCD-related symptoms
Important: The TFT LCD for the notebook computer contains many thin-film
transistors (TFTs). The presence of a small number of dots that are missing,
discolored, or always lighted is characteristic of TFT LCD technology, but
excessive pixel problems can cause viewing concerns.
If the LCD you are servicing has two or less visible defective pixels, it should not
be considered faulty. However, if the LCD has three or more visible defective
pixels, it will be deemed as defective by Lenovo and it should be replaced.
Notes:
v This policy applies to all ThinkPad Notebooks purchased on 1 January,
2008 or later.
v Lenovo will not provide replacement if the LCD is within specification as
we cannot guarantee that any replacement LCD will have zero pixel defects.
v One pixel consists of R, G, B sub-pixels.

Intermittent problems
Intermittent system hang problems can be due to a variety of causes 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
problem recurs.
When analyzing an intermittent problem, do the following:
1. Run the diagnostic test for the system board in loop mode at least 10 times.
2. If no error is detected, do not replace any FRUs.
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
If the diagnostic tests did not identify the adapter or device that has failed, if
wrong devices are installed, or if the system simply is not operating, follow these
procedures to isolate the failing FRU (do not isolate FRUs that have no defects).
Verify that all attached devices are supported by the computer.
Verify that the power supply being used at the time of the failure is operating
1. Turn off the computer.
2. Visually check each FRU for damage. Replace any damaged FRU.
3. Remove or disconnect all of the following devices:
a. Non-ThinkPad devices
b. Printer, mouse, and other external devices
c. Battery pack
d. Hard disk drive
e. External diskette drive or optical drive
f. DIMM
g. Optical disk or diskette in the internal drive
h. PC Cards
4. Turn on the computer.
5. Determine whether the problem has been solved.
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 nondefective FRU):

Retaining serial numbers
This section includes the following descriptions:
Restoring the serial number of the system unit
When the computer was manufactured, the EEPROM on the system board was
loaded with the serial numbers of the system and all major components. These
numbers need to remain the same throughout the life of the computer.
If you replace the system board, you must restore the serial number of the system
unit to its original value.
Before replacing the system board, save the original serial number by doing the
following:
1. Install the LENOVO ThinkPad Hardware Maintenance Diskette Version 1.76 or
later, and restart the computer.
2. From the main menu, select 1. Set System Identification.
3. Select 2. Read S/N data from EEPROM.
The serial number of each device in your computer is displayed; the serial number
of the system unit is listed as follows:
v 20: Serial number
Write down that number.
Note: The serial number of the system unit is also written on the label attached to
the bottom of the computer.
After you have replaced the system board, restore the serial number by doing the
following:
1. Install the LENOVO ThinkPad Hardware Maintenance Diskette Version 1.76 or
later and restart the computer.
2. From the main menu, select 1. Set System Identification.
3. Select 1. Add S/N data from EEPROM.
Follow the instructions on the screen.
If the MTM and Product ID numbers differ from each other on the rear label, use
what is shown for the Product ID field. See example below:
MTM on rear label:
TTTT-CTO S/N SSSSSSS
Product ID on rear label:
TTTT-MMM (Use this number when setting Serial Number)
In the example, the Serial Number to be input is ’1STTTTMMMSSSSSSS’.
Retaining the UUID
The Universally Unique Identifier (UUID) is a 128-bit number uniquely assigned to
your computer at production and stored in the EEPROM of your system board.
78 ThinkPad X301 Hardware Maintenance Manual
The algorithm that generates the number is designed to provide unique IDs until
the year A.D. 3400. No two computers in the world have the same number.
When you replace the system board, you must set the UUID on the new system
board as follows:
1. Install the LENOVO ThinkPad Hardware Maintenance Diskette Version 1.76 or
later, and restart the computer.
2. From the main menu, select 4. Assign UUID.
A new UUID is created and written. If a valid UUID already exists, it is not
overwritten.
Reading or writing the ECA information
Information on Engineering Change Announcements (ECA) are stored in the
EEPROM of the system board. The electronic storage of this information simplifies
the procedure to check if the ECA has been previously applied to a machine. The
machine does not need to be disassembled to check for the ECA application.
To check what ECAs have been previously applied to the machine, use the ECA
Information Read/Write function on the LENOVO ThinkPad Hardware
Maintenance Diskette Version 1.76 or later.
1. Insert the LENOVO ThinkPad Hardware Maintenance Diskette Version 1.76 or
later, and restart the computer.
2. From the main menu, select 6. Set ECA Information.
3. To read ECA information, select 2. Read ECA/rework number from EEPROM
and follow the instruction.
4. To read box build date, select 5. Read box build date from EEPROM, and
follow the instruction on the screen.
After an ECA has been applied to the machine, the EEPROM must be updated to
reflect the ECA’s application. Use the LENOVO ThinkPad Hardware Maintenance
Diskette Version 1.76 or later to update the EEPROM.
Note: Only the ECA number is stored in the EEPROM. The machine type of the
ECA is assumed be the same as the machine type of the machine that had the ECA
applied to it.
1. Insert the LENOVO ThinkPad Hardware Maintenance Diskette Version 1.76 or
later, and restart the computer.
2. From the main menu, select 6. Set ECA Information.
3. To write ECA information, select 1. Write ECA/rework number from EEPROM,
and follow the instruction.
4. To write box build date, select 4. Write box build date from EEPROM, and
follow the instruction on the screen.
If the system board is being replaced, try to read the ECA information from the old
system board and transfer the information to the new system. If the system board
is inoperable, this will not be possible.
FRU replacement notices 79
80 ThinkPad X301 Hardware Maintenance Manual
Removing and replacing a FRU
This chapter presents directions and drawings for use in removing and replacing a
FRU. Be sure to observe the following general rules:
1. Do not try to service any computer unless you have been trained and certified.
An untrained person runs the risk of damaging parts.
3. Begin by removing any FRUs that have to be removed before the failing FRU.
Any such FRUs are listed at the top of the page. Remove them in the order in
which they are listed.
4. Follow the correct sequence in the steps for removing the FRU, as given in the
drawings by the numbers in square callouts.
5. When turning a screw to replace a FRU, turn it in the direction as given by the
arrow in the drawing.
6. When removing the FRU, move it in the direction as given by the arrow in the
drawing.
7. To put the new FRU in place, reverse the removal procedure and follow any
notes that pertain to replacement. For information about connecting and
arranging internal cables, see “Locations” on page 135.
8. When replacing a FRU, use the correct screw as shown in the procedures.
DANGER
Before removing any FRU, turn off the computer, unplug all power cords
from electrical outlets, remove the battery pack, and then disconnect any
interconnecting cables.
Attention: After replacing a FRU, do not turn on the computer until you have
made sure that all screws, springs, and other small parts are in place and none are
loose inside the computer. Verify this by shaking the computer gently and listening
for rattling sounds. Metallic parts or metal flakes can cause electrical short circuits.
Attention: The system board is sensitive to, and can be damaged by, electrostatic
discharge. Before touching it, establish personal grounding by touching a ground
point with one hand or by using an electrostatic discharge (ESD) strap (P/N
6405959).

Important notices for handling the system board:
When handling the system board, bear the following in mind.
v The system board has an accelerometer, which can be broken by applying
several thousands of G-forces.
Note: Dropping a system board from a height of as little as 6 inches so that it
falls flat on a hard bench can subject the accelerometer to as much as 6,000 G’s
of shock.
v Be careful not to drop the system board on a bench top that has a hard
surface, such as metal, wood, or composite.
v If a system board is dropped, you must test it, using PC-Doctor for DOS, to
make sure that the HDD Active Protection still functions (see below).
Note: If the test shows that HDD Active Protection is not functioning, be sure
to document the drop in any reject report, and replace the system board.
v Avoid rough handling of any kind.
v At every point in the process, be sure not to drop or stack the system board.
v If you put a system board down, be sure to put it only on a padded surface
such as an ESD mat or conductive corrugated material.
After replacing the system board, run PC-Doctor for DOS to make sure that
HDD Active Protection still functions. The procedure is as follows:
1. Place the computer on a horizontal surface.
2. Run Diagnostics --> ThinkPad Devices --> HDD Active Protection Test.
Attention:: Do not apply physical shock to the computer while the test is
running.
For access, remove these FRUs, in order:

Parts list
This section contains following lists of the service parts.
Notes:
v Each FRU is available for all types or models, unless specific types or models
are specified.
v FRU with specific models listed and described as xxU (where U is an example
of a country designator) should be used for all models ending in U.
v FRU with specific models listed and described as 3Dx (where 3D is an
example of a unique configuration) should be used for all of these models,
unless specific country or region designator is specified.
v A CRU (customer replaceable unit) is identified by a single asterisk (*) or two
asterisks (**) in the CRU ID column. An N in the CRU ID column means that
the part is not a CRU. A single asterisk (*) means that the part is a Self-service
CRU; two asterisks (**) means that the part is an Optional-service CRU.
ThinkPad computers contain the following types of CRUs:
Self-service CRUs
These CRUs unplug or are held by no more than two screws.
Examples of these types of CRUs include an AC adapter, a power
cord, a battery, and a hard disk drive. Other Self-service CRUs
depending on product design may include a memory, a wireless card,
a keyboard, and a palm rest with finger print reader and touchpad.
Optional-service CRUs
These CRUs are isolated parts within the computer that are concealed
by an access panel that is typically secured by more than two screws.
Once the access panel is removed, the specific CRU is visible.
v A RoHS compliant FRU is identified by an R. An N in the RoHS ID column
means the part is not a RoHS compliant FRU.
v FRUs marked with ꢀOPꢁ are available as options.
