Chapter 1. About this manual  
This manual contains service and reference information for ThinkCentre® computers listed on the cover. It is  
intended only for trained servicers who are familiar with Lenovo computer products.  
Before servicing a Lenovo product, be sure to read the Safety Information. See Chapter 2 "Safety  
information" on page 3.  
The Symptom-to-FRU Index and Additional Service Information chapters are not specific to any machine  
type and are applicable to all ThinkCentre computers.  
This manual includes a complete FRU part number listing for each machine type and model listed on the  
cover. If you have internet access, FRU part numbers are also available at:  
http:/www.lenovo.com/support

Important information about replacing RoHS compliant FRUs  
RoHS, The Restriction of Hazardous Substances in Electrical and Electronic Equipment Directive  
(2002/95/EC) is a European Union legal requirement affecting the global electronics industry. RoHS  
requirements must be implemented on Lenovo products placed on the market and sold in the  
European Union after June 2006. Products on the market before June 2006 are not required to  
have RoHS compliant parts. If the parts are not compliant originally, replacement parts can also

be noncompliant, but in all cases, if the parts are compliant, the replacement parts must also be  
compliant.  
Note: RoHS and non-RoHS FRU part numbers with the same fit and function are identified with unique  
FRU part numbers.  
Lenovo plans to transition to RoHS compliance well before the implementation date and expects its suppliers  
to be ready to support Lenovo's requirements and schedule in the EU. Products sold in 2005, will contain  
some RoHS compliant FRUs. The following statement pertains to these products and any product Lenovo  
produces containing RoHS compliant parts.  
RoHS compliant ThinkCentre parts have unique FRU part numbers. Before or after June, 2006, failed RoHS  
compliant parts must always be replaced using RoHS compliant FRUs, so only the FRUs identified as  
compliant in the system HMM or direct substitutions for those FRUs can be used.

ThinkCentre Hardware Maintenance Manual  
Chapter 2. Safety information  
This chapter contains the safety information that you need to be familiar with before servicing a computer.  
General safety  
Follow these rules to ensure general safety:  
• Observe good housekeeping in the area of the machines during and after maintenance.  
• When lifting any heavy object:  
1. Ensure you can stand safely without slipping.  
2. Distribute the weight of the object equally between your feet.  
3. Use a slow lifting force. Never move suddenly or twist when you attempt to lift.  
4. Lift by standing or by pushing up with your leg muscles; this action removes the strain from the  
muscles in your back. Do not attempt to lift any objects that weigh more than 16 kg (35 lb) or objects  
that you think are too heavy for you.  
• Do not perform any action that causes hazards to the customer, or that makes the equipment unsafe.  
• Before you start the machine, ensure that other service representatives and the customer's personnel are  
not in a hazardous position.  
• Place removed covers and other parts in a safe place, away from all personnel, while you are servicing  
the machine.  
• Keep your tool case away from walk areas so that other people will not trip over it.  
• Do not wear loose clothing that can be trapped in the moving parts of a machine. Ensure that your sleeves  
are fastened or rolled up above your elbows. If your hair is long, fasten it.  
• Insert the ends of your necktie or scarf inside clothing or fasten it with a nonconductive clip, approximately  
8 centimeters (3 inches) from the end.  
• Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your clothing.  
Remember: 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.  
Electrical safety  
CAUTION:  
Electrical current from power, telephone, and communication cables can be hazardous. To avoid  
personal injury or equipment damage, disconnect the attached power cords, telecommunication  
systems, networks, and modems before you open the server/workstation covers, unless instructed  
otherwise in the installation and configuration procedures.  
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 Field Replaceable 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.  
Remember: 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.  
Remember: There must be a complete circuit to cause electrical shock. By observing the above rule,  
you may prevent a current from passing through your body.  
– When using testers, set the controls correctly and use the approved probe leads and accessories for  
that tester.  
– Stand on suitable rubber mats (obtained locally, if necessary) to insulate you from grounds such as  
metal floor strips and machine frames.  
Observe the special safety precautions when you work with very high voltages; these instructions are in  
the safety sections of maintenance information. Use extreme care when measuring high voltages.  
• Regularly inspect and maintain your electrical hand tools for safe operational condition.  
• Do not use worn or broken tools and testers.  
• Never assume that power has been disconnected from a circuit. First, check that it has been powered-off.  
• Always look carefully for possible hazards in your work area. Examples of these hazards are moist floors,  
nongrounded power extension cables, power surges, and missing safety grounds.  
• Do not touch live electrical circuits with the reflective surface of a plastic dental mirror. The surface is  
conductive; such touching can cause personal injury and machine damage.  
• Do not service the following parts with the power on when they are removed from their normal operating  
places in a machine:  
– Power supply units  
– Pumps  
– Blowers and fans  
– Motor generators  
and similar units. (This practice ensures correct grounding of the units.)  
• If an electrical accident occurs:  
– Use caution; do not become a victim yourself.  
– Switch off power.  
– Send another person to get medical aid.

Voltage-selection switch  
Some computers are equipped with a voltage-selection switch located near the power-cord connection  
point on the computer. If your computer has a voltage-selection switch, ensure that you set the switch to  
match the voltage available at your electrical outlet. Setting the voltage-selection switch incorrectly can  
cause permanent damage to the computer.  
If your computer does not have a voltage-selection switch, your computer is designed to operate only at the  
voltage provided in the country or region where the computer was originally purchased.  
If you relocate your computer to another country, be aware of the following:  
• If your computer does not have a voltage-selection switch, do not connect the computer to an electrical  
outlet until you have verified that the voltage provided is the same as it was in the country or region  
where the computer was originally purchased.  
• If your computer has a voltage selection switch, do not connect the computer to an electrical outlet until  
you have verified that the voltage-selection switch is set to match the voltage provided in that country  
or region.  
If you are not sure of the voltage provided at your electrical outlet, contact your local electric company or  
refer to official Web sites or other literature for travelers to the country or region where you are located.  
Safety inspection guide  
The intent of this inspection guide is to assist you in identifying potentially unsafe conditions on these  
products. Each machine, as it was designed and built, had required safety items installed to protect users  
and service personnel from injury. This guide addresses only those items. However, good judgment should  
be used to identify potential safety hazards due to attachment of features or options not covered by this  
inspection guide.  
If any unsafe conditions are present, you must determine how serious the apparent hazard could be and  
whether you can continue without first correcting the problem.  
Consider these conditions and the safety hazards they present:  
• Electrical hazards, especially primary power (primary voltage on the frame can cause serious or fatal  
electrical shock).  
• Explosive hazards, such as a damaged CRT face or bulging capacitor  
• Mechanical hazards, such as loose or missing hardware  
The guide consists of a series of steps presented in a checklist. Begin the checks with the power off, and  
the power cord disconnected.  
Checklist:  
1. Check exterior covers for damage (loose, broken, or sharp edges).  
2. Power-off the computer. Disconnect the power cord.  
3. Check the power cord for:  
a. A third-wire ground connector in good condition. Use a meter to measure third-wire ground continuity  
for 0.1 ohm or less between the external ground pin and frame ground.  
b. The power cord should be the appropriate type as specified in the parts listings.  
c. Insulation must not be frayed or worn.  
4. Remove the cover.  
Chapter 2 Safety information  
5
   
5. Check for any obvious alterations. Use good judgment as to the safety of any alterations.  
6. Check inside the unit for any obvious unsafe conditions, such as metal filings, contamination, water or  
other liquids, or signs of fire or smoke damage.  
7. Check for worn, frayed, or pinched cables.  
8. Check that the power-supply cover fasteners (screws or rivets) have not been removed or tampered with.  
Handling electrostatic discharge-sensitive devices  
Any computer part containing transistors or integrated circuits (ICs) should be considered sensitive to  
electrostatic discharge (ESD). ESD damage can occur when there is a difference in charge between objects.  
Protect against ESD damage by equalizing the charge so that the machine, the part, the work mat, and the  
person handling the part are all at the same charge.  
Notes:  
1. Use product-specific ESD procedures when they exceed the requirements noted here.  
2. Make sure that the ESD protective devices you use have been certified (ISO 9000) as fully effective.  
When handling ESD-sensitive parts:  
• Keep the parts in protective packages until they are inserted into the product.  
• Avoid contact with other people while handling the part.  
• Wear a grounded wrist strap against your skin to eliminate static on your body.  
• Prevent the part from touching your clothing. Most clothing is insulative and retains a charge even when  
you are wearing a wrist strap.  
• Use the black side of a grounded work mat to provide a static-free work surface. The mat is especially  
useful when handling ESD-sensitive devices.  
• Select a grounding system, such as those listed below, to provide protection that meets the specific  
service requirement.  
Note: The use of a grounding system is desirable but not required to protect against ESD damage.  
– Attach the ESD ground clip to any frame ground, ground braid, or green-wire ground.  
– Use an ESD common ground or reference point when working on a double-insulated or  
battery-operated system. You can use coax or connector-outside shells on these systems.  
– Use the round ground-prong of the ac plug on ac-operated computers.  
Grounding requirements  
Electrical grounding of the computer is required for operator safety and correct system function. Proper  
grounding of the electrical outlet can be verified by a certified electrician.

Chapter 4. General Checkout  
Attention  
The drives in the computer you are servicing might have been rearranged or the drive startup sequence  
changed. Be extremely careful during write operations such as copying, saving, or formatting. Data or  
programs can be overwritten if you select an incorrect drive.  
General error messages appear if a problem or conflict is found by an application program, the operating  
system, or both. For an explanation of these messages, refer to the information supplied with that software  
package.  
Before replacing any FRUs, ensure that the latest level of BIOS is installed on the system. A down-level BIOS  
might cause false errors and unnecessary replacement of the system board. For more information on how to  
determine and obtain the latest level BIOS, see "BIOS levels" on page 467.  
Use the following procedure to help determine the cause of the problem:  
1. Power-off the computer and all external devices.  
2. Check all cables and power cords.  
3. Set all display controls to the middle position.  
4. Power-on all external devices.  
5. Power-on the computer.  
• Look for displayed error codes  
• Listen for beep codes  
• Look for readable instructions or a main menu on the display.  
If you did not receive the correct response, proceed to step 6 on page 31.  
If you do receive the correct response, proceed to step 7 on page 31.  
6. Look at the following conditions and follow the instructions:  
• If you hear beep codes during POST, go to "Beep symptoms" on page 61.  
• If the computer displays a POST error, go to "POST error codes" on page 62.  
• If the computer hangs and no error is displayed, continue at step 7 on page 31.  
7. Run the Diagnostic programs. See Chapter 5 "Diagnostics" on page 33.  
• If you receive an error, replace the part that the diagnostic program calls out or go to "Diagnostic  
error codes" on page 44.  
• If the test stops and you cannot continue, replace the last device tested.  
Problem determination tips  
Due to the variety of hardware and software combinations that can be encountered, use the following  
information to assist you in problem determination. If possible, have this information available when  
requesting assistance from Service Support and Engineering functions.  
• Machine type and model  
• Processor or hard disk upgrades  
• Failure symptom  
– Do diagnostics indicate a failure?  
– What, when, where, single, or multiple systems?  
– Is the failure repeatable?  
© Copyright Lenovo 2008, 2010  
31  
       
– Has this configuration ever worked?  
– If it has been working, what changes were made prior to it failing?  
– Is this the original reported failure?  
• Diagnostics version  
– Type and version level  
• Hardware configuration  
– Print (print screen) configuration currently in use  
– BIOS level  
• Operating system software  
– Type and version level  
Notes: To eliminate confusion, identical systems are considered identical only if they:  
1. Are the exact machine type and models  
2. Have the same BIOS level  
3. Have the same adapters/attachments in the same locations  
4. Have the same address jumpers/terminators/cabling  
5. Have the same software versions and levels  
6. Have the same Diagnostic Diskettes (version)  
7. Have the same configuration options set in the system  
8. Have the same setup for the operating system control files  
Comparing the configuration and software set-up between “working and non-working” systems will often  
lead to problem resolution.

POST error codes  
Each time you power-on the system, it performs a series of tests that check the operation of the system  
and some options. This series of tests is called the Power-On Self-Test, or POST. POST does the following  
operations.  
• Checks some basic system-board operations  
• Checks the memory operation  
• Starts the video operation  
• Verifies that the boot drive is working  
If the POST detects a problem, an error message appears on the screen. A single problem can cause several  
error messages to appear. When you correct the cause of the first error message, the other error messages  
probably will not appear on the screen the next time you turn on the system.  
POST Error Message  
Description/Action  
CMOS battery failed  
The CMOS battery is no longer functional.  
Replace the battery.  
CMOS checksum error - defaults loaded  
Checksum of CMOS is incorrect.  
The computer loads the default configuration settings.  
This error might indicate that CMOS has become corrupt  
due to a weak CMOS battery.  
CPU at nnnn  
nnnn is the running speed of the microprocessor.  
Pressing Esc skips the full memory test  
Press Esc to skip memory test  
HARD DISK INSTALL FAILURE  
Cannot find or initialize the hard disk drive controller or  
the drive.  
Make sure the hard disk drive is correctly installed.  
If no hard disk drives are installed, make sure the hard  
disk drive selection in Setup is set to NONE.  
Keyboard error or no keyboard present  
Cannot initialize the keyboard.  
Make sure the keyboard is properly connected to the  
computer and that no keys are held pressed during POST.  
To purposely configure the computer without a keyboard,  
set the error halt condition in Setup to HALT ON ALL, BUT  
KEYBOARD. The BIOS then ignores the missing keyboard  
during POST.  
Memory Test:  
This message displays during a full memory test, counting  
down the memory areas being tested.  
Memory test fail  
If POST detects an error during memory testing, additional  
information appears. This information gives specifics  
about the type and location of the memory error.

Completing the FRU replacement  
After replacing FRUs, you need to install any removed parts, replace the cover, and reconnect any cables,  
including telephone lines and power cords. Also, depending on the FRU that is replaced, you might need to  
confirm the updated information in the Setup Utility program.  
Note: When the power cord is first plugged in, the computer might appear to turn on for a few seconds and  
then turn off. This is a normal sequence to enable the computer to initialize.  
1. Ensure that all components have been reassembled correctly and that no tools or loose screws are left  
inside your computer.  
2. Reposition any cables that might impede the replacement of the computer cover.  
Important: Correctly route all power supply cables to avoid interference with the drive bay assembly.  
Keep cables clear of the hinges and sides of the computer chassis.  
3. Position the computer cover on the chassis so that the rail guides on the sides of the cover engage the  
rails and push the cover to the closed position until it snaps into position.
