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 representatives 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.

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 personnel 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.

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.

Important service information  
This chapter presents following important service information that applies to all  
machine types supported by this manual:  
Important:  
BIOS and device driver fixes are customer-installable. The BIOS and device  
drivers are posted on the customer support site http://www.lenovo.com/support  
System Disassembly/Reassembly videos that show the FRU removals or  
replacements for the Lenovo® authorized service technicians are available in the  
Advise customers to contact the Customer Support Center at 800-426-7378 if they  
need assistance in obtaining or installing any software fixes, drivers, and BIOS  
downloads.  
Customers in Canada should call the Customer Support Center at 800-565-3344  
for assistance or download information.  
Strategy for replacing FRUs  
Before replacing parts:  
Make sure that all software fixes, drivers, and BIOS downloads are installed  
before replacing any FRUs listed in this manual.  
After a system board is replaced, ensure that the latest BIOS is loaded to the  
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  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
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 eSupport can be accessed at the following Web site: http://www.lenovo.com/  
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.

This chapter presents following information:  
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:  
v Only certified trained personnel should service the computer.  
v Before replacing any FRU, read the entire page on removing and replacing  
FRUs.  
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.

7. Check that the battery pack supplies power when you turn on the computer.  
If you suspect a power problem, see the appropriate one of the following power  
supply checkouts:  
Checking the AC adapter  
You are here because the computer fails only when the AC adapter is used.  
v If the power problem occurs only when the docking station or the port replicator  
is used, replace the docking station or the port replicator.  
v If the power-on indicator does not turn on, check the power cord of the AC  
adapter for correct continuity and installation.  
v If the computer does not charge during operation, go to “Checking operational

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 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 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 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:  
Terminal  
Voltage (V dc)  
+ 0 to + 12.6  
Ground (-)  
1
7
7(-)  
6(-)

2(+)  
1(+)  
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 .  
If the resistance is not correct, replace the battery pack. If the resistance is  
correct, replace the system board.

Restoring the factory contents by using Product Recovery discs  
When the hard disk drive (HDD) or solid state drive (SSD) is replaced because of a  
failure, no Product Recovery program is on the new drive. In this case, you must  
use the recovery discs for the computer. Order the recovery discs and the drive at  
the same time so that you can recover the new drive with the pre-installed  
software when they arrive. For information on which discs to order, see “Recovery  
To install the factory contents by using Product Recovery discs, do the following:  
Note: Recovery takes several hours. The length of time depends on the method  
you use. If you use recovery discs, recovery takes at least five hours.

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  
can be booted. For how to remove the POP, see “How to remove the power-on  
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  
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 servicers 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  
servicer, there is no service procedure to reset the password. The system board  
must be replaced for a scheduled fee.

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. Devices attached to the docking station or the port replicator  
c. Printer, mouse, and other external devices  
d. Battery pack  
e. Hard disk drive  
f. External diskette drive or optical drive  
g. DIMM  
h. Optical disk or diskette in the internal drive  
i. 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):  
a. System board  
b. LCD assembly

Loose screws can cause a reliability problem. In the ThinkPad Notebook, this  
problem is addressed with special nylon-coated screws that have the following  
characteristics:  
v They maintain tight connections.  
v They do not easily come loose, even with shock or vibration.  
v They are harder to tighten.  
v Each one should be used only once.  
Do the following when you service this machine:  
v Keep the screw kit (for the P/N, see “Miscellaneous parts” on page 159) in your  
tool bag.  
v Always use new screws.  
v Use a torque screwdriver if you have one.  
Tighten screws as follows:  
v Plastic to plastic  
Turn an additional 90 degrees after the screw head touches the surface of the  
plastic part:  
90 degrees more  
(Cross-section)  
v Logic card to plastic  
Turn an additional 180 degrees after the screw head touches the surface of the  
logic card:  
180 degrees more  
(Cross-section)  
v Torque driver  
If you have a torque driver, refer to the “Torque” column for each step.  
v Make sure that you use the correct screw. If you have a torque screwdriver,  
tighten all screws firmly to the torque shown in the table. Never use a screw  
that you removed. Use a new one. Make sure that all of the screws are  
tightened firmly.

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 T400s Hardware Maintenance Manual  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
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.

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.  
2. Before replacing any FRU, review “FRU replacement notices” on page 77.  
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 141.  
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).

1160 System board, fan assembly, and 34-mm ExpressCard slot frame  
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.

Parts list  
This chapter 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 Notebooks 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 FRUs marked with ꢀOPꢁ are available as options.
