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. 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.
• Do not perform any action that causes hazards to the customer, or that makes the equipment unsafe.
• Before you start the machine, make sure that other service technicians 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 toolcase 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. Make sure 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, about 8
centimeters (3 inches) from the end.
• Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your clothing.
Attention: Metal objects are good electrical conductors.
• Wear safety glasses when you are hammering, drilling, soldering, cutting wire, attaching springs, using
solvents, or working in any other conditions that might be hazardous to your eyes.
• After service, reinstall all safety shields, guards, labels, and ground wires. Replace any safety device
that is worn or defective.
• Reinstall all covers correctly before returning the machine to the customer.
• 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.
• Find the room emergency power-off (EPO) switch, disconnecting switch, or electrical outlet. If an electrical
accident occurs, you can then operate the switch or unplug the power cord quickly.
• Do not work alone under hazardous conditions or near equipment that has hazardous voltages.
• Disconnect all power before:
– Performing a mechanical inspection
– Working near power supplies
– Removing or installing main units
• Before you start to work on the machine, unplug the power cord. If you cannot unplug it, ask the customer
to power-off the wall box that supplies power to the machine, and to lock the wall box in the off position.
• If you need to work on a machine that has exposed electrical circuits, observe the following precautions:
– Ensure that another person, familiar with the power-off controls, is near you.
Attention: Another person must be there to switch off the power, if necessary.
– Use only one hand when working with powered-on electrical equipment; keep the other hand in your
pocket or behind your back.
Attention: 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.
• 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
– Motor generators
– Similar units to listed above
This practice ensures correct grounding of the units.
• If an electrical accident occurs:
– Use caution; do not become a victim yourself.
– Switch off power.

– Send another person to get medical aid.
Safety inspection guide
The 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:
• 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 a bulging capacitor
• 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.
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.
Chapter 1. Safety information
3
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 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 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.

Important:
• Advise customers to contact the Lenovo Customer Support Center if they need any assistance in
obtaining or installing any software fixes, drivers, and UEFI BIOS downloads. Telephone numbers for
Lenovo Support are available at:http://www.lenovo.com/support/phone
• System Disassembly/Reassembly videos that show the FRU removals or replacements for the Lenovo®
authorized service technicians are available in the following support site:
http://www.lenovoservicetraining.com/ion/
Strategy for replacing FRUs
Before replacing parts:
Make sure that all software fixes, drivers, and UEFI BIOS downloads are installed before replacing any
FRUs listed in this manual.
After a system board is replaced, ensure that the latest UEFI BIOS is loaded to the system board before
completing the service action.
To download software fixes, drivers, and UEFI BIOS, do as follows:
1. Go to http://www.lenovo.com/support.
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:
• If you are instructed to replace a FRU but the replacement 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 replacing one of them does not correct the problem,
reinstall that board, and then replace the other one.
• 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.
If your computer is shipped with an mSATA drive and a solid-state drive or hard disk drive, the mSATA drive
will be seen as hard disk 0 in the system, and assigned drive C:. The solid-state drive or hard disk drive will
be seen as hard disk 1, and assigned drive D:. The mSATA drive is installed in the wireless WAN card slot of
the computer. The Lenovo preloaded software is installed on the mSATA drive.
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:
• Do not drop a system board or apply any excessive force to it.
• Avoid rough handling of any kind.
• 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 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 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.
32
Hardware Maintenance Manual
• 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).
• The PEW record is the 4-digit MT and 3-digit model, where model = “CTO” (Example: 1829-CTO).
• eSupport will show both the CTO and CMV machine type models (Example: 1829-CTO and 1829-W15
will be found on the eSupport site.)
• 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 Hardware Maintenance Manual.
Using PEW
• 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.
• 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).
• PEW can be accessed at the following Web site:
http://www.lenovo.com/support/site.wss/document.do?lndocid=LOOK-WARNTY
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.
Using eSupport
For key commodities (examples - hard disk drive, system board, microprocessor, LCD, and memory)
eSupport can be used to view the warranty status of key commodities built in a particular machine serial (this

The descriptions in this chapter apply to any ThinkPad model that supports the PC-Doctor® for DOS
diagnostics program. Some descriptions might not apply to your particular computer.
Before you go to the checkout guide, be sure to read the following important notes.
Important notes:
• Only certified trained personnel should service the computer.
• Before replacing any FRU, read the entire page on removing and replacing FRUs.
• When you replace FRUs, it is recommended to use new nylon-coated screws.
• 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.
• 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.
• 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.
• Be careful not to replace a nondefective FRU.
What to do first

Chapter 3. General checkout
43
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.
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:
1(+)
2(+)
5
3 4
6(-)
7(-)
Terminal
Voltage (V dc)
1
+ 0 to + 12.6
7

3. If the voltage is less than +11.0 V dc, the battery pack has been discharged.
Note: Recharging will take at least 3 hours, even if the indicator does not turn on.
If the voltage is still less than +11.0 V dc after recharging, replace the battery.
4. If the voltage is more than +11.0 V dc, measure the resistance between battery terminals 5 and 7.
The resistance must be 4 to 30 K Ω. If the resistance is not correct, replace the battery pack. If the
resistance is correct, replace the system board.
Checking the backup battery
Do the following:
1. Power off the computer, and unplug the ac adapter from it.
2. Turn the computer upside down.
3. Remove the battery pack (see “1010 Battery pack” on page 68).
4. Remove the backup battery (see “1090 Backup battery” on page 83).

As many as three passwords may be needed for any ThinkPad Notebook: the power-on password, the
hard disk password, and the supervisor password.
If any of these passwords has been set, a prompt for it will be displayed on the screen whenever the
computer is turned on. The computer does not start until the password is entered.
Note: If only a supervisor password is set, the password prompt will not be displayed when the operating
system is started.
Power-on password
A power-on password protects the system from being powered on by an unauthorized person. The
password must be turned on before an operating system can be started. For instructions on how to remove
the power-on password, see “How to remove the power-on password” on page 49.
Hard disk password
There are two hard disk passwords:
• User hard disk password - for the user
• Master hard disk password - for the system administrator, who can use it to get access to the hard disk
even if the user has changed the user hard disk password
Note: There are two modes for the hard disk password: User only and Master + User. The Master + User
mode requires two hard disk passwords; the system administrator enters both in the same operation. The
system administrator then provides the user hard disk password to the system user.
Attention: If the user hard disk password has been forgotten, check whether a master hard disk password
has been set. If it has, it can be used for access to the hard disk drive. If no master hard disk password is
available, neither Lenovo nor Lenovo authorized service technicians provide any services to reset either
the user or the master hard disk password, or to recover data from the hard disk drive. The hard disk drive
can be replaced for a scheduled fee.
For how to remove the hard disk password, see “How to remove the hard disk password” on page 50.
Supervisor password
A supervisor password protects the system information stored in the ThinkPad Setup. The user must enter
the supervisor password in order to get access to the ThinkPad Setup and change the system configuration.
Attention: If the supervisor password 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 power-on password that you have forgotten, do the following:
(A) If no supervisor password has been set:
1. Turn off the computer and disconnect the ac power adapter.
2. Remove the battery pack. For how to remove the battery pack, see “1010 Battery pack” on page 68.

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:
• This policy applies to all ThinkPad Notebooks purchased on 1 January, 2008 or later.
• Lenovo will not provide replacement if the LCD is within specification as we cannot guarantee that
any replacement LCD will have zero pixel defects.
• 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 correctly. (See “Power system
checkout” on page 42.)
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. Devices attached to the docking station or the port replicator

• “Restoring the serial number of the system unit” on page 64
• “Retaining the UUID” on page 65
• “Reading or writing the ECA information” on page 65
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:
• 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:
64
Hardware Maintenance Manual
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. 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.

Chapter 8. Removing and replacing a FRU
External CRU statement to customers:
Some problems with your product can be resolved with a replacement part you can install yourself, called
a “Customer Replaceable Unit” or “CRU.” Some CRUs are designated as Self-service CRUs and others
are designated as Optional-service CRUs. Installation of Self-service CRUs is your responsibility; you may
request that Lenovo installs an Optional-service CRU according to the warranty service for your product.
Where you are installing the CRU, Lenovo will ship the CRU to you. CRU information and replacement
instructions are shipped with your product and are available from Lenovo at any time upon request. You may
find a list of CRUs in the publications that ship with your product or at http://www.lenovo.com/CRUs. You
may be required to return the defective part that is replaced by the CRU. When return is required: (1) return
instructions, a prepaid shipping label, and a container will be included with the replacement CRU; and (2) you
may be charged for the replacement CRU if Lenovo does not receive the defective part within thirty (30) days
of your receipt of the replacement CRU. See your Lenovo Limited Warranty documentation for full details.
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.
2. Before replacing any FRU, review Chapter 7 “FRU replacement notices” on page 63.
3. Begin by removing any FRUs that have to be removed before replacing the failing FRU. Such FRUs are
listed in each FRU replacement section. Remove them in the order in which they are listed.
4. Follow the correct sequence in the steps for removing a 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 a 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 Chapter 9 “Locations”
on page 115.
8. When replacing a FRU, use the correct screws 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, read the following:
• The system board has an accelerometer, which can be broken when several thousands of G-forces
are applied.
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.
• Be careful not to drop the system board on a bench top that has a hard surface, such as metal, wood, or
composite.
• If a system board is dropped, test it using PC-Doctor for DOS if the system supports PC-Doctor for DOS,
to make sure that the HDD Active Protection™ still functions.
Note: If the test shows that the HDD Active Protection system is not functioning, be sure to document the
drop in any reject report, and replace the system board.
• Avoid rough handling of any kind.
• At every point in the process, be sure not to drop or stack the system board.
• If you put a system board down, be sure to put it only on a padded surface such as an ESD mat or a
corrugated conductive material.
If the system supports PC-Doctor for DOS, after replacing the system board, run PC-Doctor for DOS to
make sure that HDD Active Protection system 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.

•
“Common service tools” on page 142
Notes:
• Each FRU is available for all types or models, unless specific types or models are specified.
• 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.
• 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.
• 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.
External CRU statement to customers:
Some problems with your product can be resolved with a replacement part you can install yourself, called
a “Customer Replaceable Unit” or “CRU.” Some CRUs are designated as Self-service CRUs and others are
designated as Optional-service CRUs. Installation of Self-service CRUs is your responsibility; you may request
that Lenovo installs an Optional-service CRU according to the warranty service for your product. Where you are
installing the CRU, Lenovo will ship the CRU to you. CRU information and replacement instructions are shipped
with your product and are available from Lenovo at any time upon request. You may find a list of CRUs in the
publications that ship with your product or at http://www.lenovo.com/CRUs. You may be required to return the
defective part that is replaced by the CRU. When return is required: (1) return instructions, a prepaid shipping label,
and a container will be included with the replacement CRU; and (2) you may be charged for the replacement CRU if
Lenovo does not receive the defective part within thirty (30) days of your receipt of the replacement CRU. See your
Lenovo Limited Warranty documentation for full details.
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 the ac power adapter, power cord, battery, and hard disk drive. Other Self-service CRUs
depending on product design may include the memory module, wireless card, keyboard, and 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.
• FRUs marked with OP are available as options.
