2 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 centre covers, unless instructed otherwise in
the installation and configuration procedures.

Observe the following rules when working on electrical equipment.

© Copyright Lenovo 2011, 2012 3

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 an electric 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 (FRU)
• 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 an electric shock. By observing the above
rule, you may prevent a current from passing through your body.
– When using a tester, 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.

4 ThinkCentre Hardware Maintenance Manual

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 might
have been 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 the explanation of these messages, refer to the information supplied with that software
package.

Before replacing a FRU, 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 279.

Use the following procedure to help determine the cause of a 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.
If you do receive the correct response, proceed to step 7.
6. Look at the following conditions and follow the instructions:
• If you hear beep codes during POST, go to “Beep symptoms” on page 67.
• If the computer displays a POST error, go to “POST error codes” on page 67.
• If the computer hangs and no error is displayed, turn off the computer and the power. Then, turn the
power and the computer back on, continue at step 7.
7. Run the Diagnostic programs. See Chapter 5 “Diagnostic programs” on page 39.
• If you receive an error, replace the part that the diagnostic program calls out or go to “Diagnostic
error codes” on page 49.
• 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 drive upgrades
• Failure symptom
– Do diagnostics indicate a failure?
– What, when, where, single, or multiple systems?

© Copyright Lenovo 2011, 2012 37

 – Is the failure repeatable?
– 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

Note: 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 operating-system-controlled files

Comparing the configuration and software set-up between “working and non-working” systems will often
lead to problem resolution.

Using passwords
By using the Setup Utility program, you can set passwords to prevent unauthorized access to your computer
and data. The following types of passwords are available:
• Power-On Password

© Copyright Lenovo 2011, 2012 43

• Administrator Password
• Hard Disk Password

You do not have to set any passwords to use your computer. However, using passwords improves
computing security. If you decide to set any passwords, read the following sections.

Password considerations
A password can be any combination of up to 64 alphabetic and numeric characters. For security reasons, it
is recommended to use a strong password that cannot be easily compromised. To set a strong password,
use the following guidelines:
• Have at least eight characters in length
• Contain at least one alphabetic character and one numeric character
• Setup Utility program and hard disk drive passwords are not case sensitive
• Not be your name or your user name
• Not be a common word or a common name
• Be significantly different from your previous passwords

Power-On Password
When a Power-On Password is set, you are prompted to type a valid password each time the computer is
turned on. The computer cannot be used until the valid password is typed in.

Administrator Password
Setting an Administrator Password deters unauthorized users from changing configuration settings. If you
are responsible for maintaining the configuration settings of several computers, you might want to set an
Administrator Password.

When an Administrator Password is set, you are prompted to type a valid password each time you try to
access the Setup Utility program. The Setup Utility program cannot be accessed until a valid password
is typed in.

If both the Power-On Password and Administrator Password are set, you can type either password. However,
you must use your Administrator Password to change any configuration settings.

Hard Disk Password

Setting a Hard Disk Password prevents unauthorized access to the data on the hard disk drive. When a
Hard Disk Password is set, you are prompted to type a valid password each time you try to access the
hard disk drive.

Notes:
• After you set a Hard Disk Password, your data on the hard disk drive is protected even if the hard disk
drive is removed from one computer and installed in another.
• If the Hard Disk Password is forgotten, there is no way to reset the password or recover data from the
hard disk drive.

Setting, changing, and deleting a password

To set, change, or delete a password, do the following:
1. Start the Setup Utility program. See “Starting the Setup Utility program” on page 43.

44 ThinkCentre Hardware Maintenance Manual

POST error codes

Each time you Turn 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. The 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.

Locating internal drives
Internal drives are devices that your computer uses to read and store data. You can add drives to your
computer to increase storage capacity and enable your computer to read other types of media. Internal
drives are installed in bays. In this manual, the bays are referred to as bay 1, bay 2, and so on.

When installing or replacing an internal drive, it is important to note the type and size of the drive that you
can install or replace in each bay and correctly connect the cables to the drive installed. Refer to the
appropriate section in “Installing or replacing hardware” on page 79 for instructions on how to install or
replace internal drives for your computer.

Figure 5 “Drive bay locations” on page 78 shows the locations of the drive bays.

Handling static-sensitive devices

Do not open the static-protective package containing the new part until the defective part has been removed
from the computer and you are ready to install the new part. Static electricity, although harmless to you, can
seriously damage computer components and parts.

When you handle computer parts and components, take these precautions to avoid static-electricity damage:
• Limit your movement. Movement can cause static electricity to build up around you.

78 ThinkCentre Hardware Maintenance Manual

• Always carefully handle the parts and other computer components. Handle PCI cards, memory modules,
system boards, and microprocessors by the edges. Never touch exposed circuitry.
• Prevent others from touching the parts and other computer components.
• Before you replace a new part, touch the static-protective package containing the new part to a metal
expansion-slot cover or other unpainted metal surface on the computer for at least two seconds. This
reduces static electricity from the package and your body.
• Remove the new part from the static-protective package and directly install it in the computer without
placing it on any other surface. If it is hard for you to do this in your specific situation, place the
static-protective package of the new part on a smooth, level surface, and then place the new part on
the static-protective package.
• Do not place the part on the computer cover or other metal surface.

Locating internal drives
Internal drives are devices that your computer uses to read and store data. You can add drives to your
computer to increase storage capacity and enable your computer to read other types of media. Internal
drives are installed in bays. In this manual, the bays are referred to as bay 1, bay 2, and so on. Your
computer comes with the following factory-installed drives:
• An optical drive in bay 1
• A 3.5-inch hard disk drive in bay 3

When installing or replacing an internal drive, it is important to note the type and size of the drive that you
can install or replace in each bay and correctly connect the cables to the drive installed. Refer to the
appropriate section in “Installing or replacing hardware” on page 121 for instructions on how to install or
replace internal drives for your computer.

Figure 51 “Drive bay locations” on page 120 shows the locations of the drive bays.

Figure 51. Drive bay locations

2 Bay 2 - Card reader drive bay

3 Bay 3 - SATA hard disk drive bay (with a 3.5-inch hard disk drive installed)

Handling static-sensitive devices

Do not open the static-protective package containing the new part until the defective part has been removed
from the computer and you are ready to install the new part. Static electricity, although harmless to you, can
seriously damage computer components and parts.

When you handle computer parts and components, take these precautions to avoid static-electricity damage:
• Limit your movement. Movement can cause static electricity to build up around you.

120 ThinkCentre Hardware Maintenance Manual

• Always carefully handle the parts and other computer components. Handle PCI cards, memory modules,
system boards, and microprocessors by the edges. Never touch exposed circuitry.
• Prevent others from touching the parts and other computer components.
• Before you replace a new part, touch the static-protective package containing the new part to a metal
expansion-slot cover or other unpainted metal surface on the computer for at least two seconds. This
reduces static electricity from the package and your body.
• Remove the new part from the static-protective package and directly install it in the computer without
placing it on any other surface. If it is hard for you to do this in your specific situation, place the
static-protective package of the new part on a smooth, level surface, and then place the new part on
the static-protective package.
• Do not place the part on the computer cover or other metal surface.

278 ThinkCentre Hardware Maintenance Manual

Chapter 11. Additional service information
This chapter provides additional information that the service representative might find helpful.

Security features
Security features in this section include the following:
• Passwords
• Vital Product Data

Hardware-controlled passwords
Use the Setup Utility program to set the hardware controlled passwords. For more information about
passwords, see “Using passwords” on page 43.

Operating system password

Note: This section applies only to computer models that have an operating system preinstalled from Lenovo.

An operating system password is very similar to a power-on password and denies access to the computer by
an unauthorized user when the password is activated. The computer is unusable until the correct password
is entered and recognized by the computer.

Vital Product Data

Each computer has a unique Vital Product Data (VPD) code stored in the nonvolatile memory on the system
board. After you replace the system board, the VPD must be updated. To update the VPD, see “Updating
(flashing) the BIOS from a disc” on page 279.

BIOS levels
An incorrect level of BIOS can cause false errors and unnecessary FRU replacement. Use the following
information to determine the current level of BIOS installed in the computer, the latest BIOS available for the
computer, and where to obtain the latest level of BIOS.
• To determine the current level of BIOS:
– Start the Setup Utility program.
– See BIOS Revision Level on the Main setup screen.
• Sources for obtaining the latest level BIOS available
1. Lenovo support web site:
http://www.lenovo.com/support
2. Lenovo Customer Support Center
3. Levels 1 and 2 Support

To update (flash) the BIOS, see “Updating (flashing) the BIOS from a disc” on page 279.

Updating (flashing) the BIOS from a disc

This section provides instructions on how to update (flash) the BIOS from a disc.

© Copyright Lenovo 2011, 2012 279

Note: You can download a self-starting bootable disc image (known as an ISO image) with the system
program updates to create a system-program-update disc. Go to:
http://www.lenovo.com/support

To update (flash) the BIOS from a disc, do the following:

1. Turn off your computer.
2. Repeatedly press and release the F12 key when turning on the computer. When the Startup Device
Menu opens, release the F12 key.
3. On the Startup Device Menu, select the desired optical drive as the startup device. Then, insert the
disc into this optical drive and press Enter. The update begins.
4. When prompted to change the serial number, it is suggested that you do not make this change by
pressing N. However, if you do want to change the serial number, press Y, then type in the serial number
and press Enter.
5. When prompted to change the machine type and model, it is suggested that you do not make this
change by pressing N. However, if you do want to change the machine type and model, press Y, then
type in the machine type and model and press Enter.
6. Follow the instructions on the screen to complete the update. After the update is completed, remove the
disc from the optical drive.

Updating (flashing) the BIOS from your operating system

Note: Because Lenovo makes constant improvements to its Web sites, the Web page contents are subject
to change without notice, including the contents referenced in the following procedure.

To update (flash) the BIOS from your operating system, do the following:
1. Go to http://support.lenovo.com.
2. Do the following to locate the downloadable files for your machine type:
a. In the Enter a product number field, type your machine type and click Go.
b. Click Downloads and drivers.
c. Select BIOS from the Refine results drop-down list box to easily locate all the BIOS related links.
d. Click the BIOS update link.
3. Click the TXT file that contains the instructions for updating (flashing) the BIOS from your operating
system.

Recovering from a POST and BIOS update failure

If the power to your computer is interrupted while the POST and BIOS is being updated, your computer
might not restart correctly. If this happens, perform the following procedure to recover from the POST and
BIOS update failure. This procedure is commonly called Boot-block Recovery.
1. Remove all media from the drives and turn off all attached devices and the computer. Then, disconnect
all power cords from electrical outlets and disconnect all cables that are connected to the computer.
2. Remove or open the computer cover. For machine types 1982, 1983, 1985, 1986, 1987, 1990, 1992,
1993, 1994, and 1995, see “Removing the computer cover” on page 79. For machine types 1996, 1997,
2002, 2010, 2208, 2209, 2221, 2224, 2226, and 2227, see “Opening the computer cover” on page 121.
3. Locate the Clear CMOS /Recovery jumper on the system board. See “Locating parts on the system
board” on page 77.

280 ThinkCentre Hardware Maintenance Manual

 4. Remove any parts and disconnect any cables that might prevent your access to the Clear CMOS
/Recovery jumper.
5. Move the jumper from the standard position (pin 1 and pin 2) to the maintenance position (pin 2 and
pin 3).
6. Reinstall any parts and reconnect any cables that have been removed or disconnected.
7. Reinstall or close the computer cover and reconnect the power cords for the computer and monitor. For
machine types 1982, 1983, 1985, 1986, 1987, 1990, 1992, 1993, 1994, and 1995, see “Completing the
parts replacement” on page 112. For machine types 1996, 1997, 2002, 2010, 2208, 2209, 2221, 2224,
2226, and 2227, see “Completing the parts replacement” on page 160.
8. Turn on the computer and then insert the POST and BIOS update (flash update) disc into the optical
drive. Wait a few minutes. Then, the recovery session begins. The recovery session will take two to
three minutes. During this time, a warning message will be displayed and no action is needed from you.
9. After the recovery session is completed, there will be no video, and your computer will automatically
turn off.
10. Repeat step 1 through step 4.
11. Move the jumper back to the standard position (pin 1 and pin 2).
12. Reinstall any parts and reconnect any cables that have been removed or disconnected.
13. Reinstall or close the computer cover and reconnect power cords and all other external cables. For
machine types 1982, 1983, 1985, 1986, 1987, 1990, 1992, 1993, 1994, and 1995, see “Completing the
parts replacement” on page 112. For machine types 1996, 1997, 2002, 2010, 2208, 2209, 2221, 2224,
2226, and 2227, see “Completing the parts replacement” on page 160.
14. Turn on the computer and remove the disc from the optical drive.

Power management
Power management reduces the power consumption of certain components of the computer such as the
system power supply, processor, hard disk drives, and some monitors.

Advanced Configuration and Power Interface (ACPI) BIOS

Being an ACPI BIOS system, the operating system is allowed to control the power management features
of the computer and the setting for Advanced Power Management (APM) BIOS mode is ignored. Not
all operating systems support ACPI BIOS mode.

Automatic Power-On features

The Automatic Power-On features within the Power Management menu allow you to enable and disable
features that turn on the computer automatically.
• RTC resume: You can specify a date and time at which the computer will be turned on automatically.
This can be either a single event or a daily event.
• Wake on LAN: If the computer has a properly configured token-ring or Ethernet LAN adapter card that is
Wake on LAN-enabled and there is remote network management software, you can use the Wake on LAN
feature. When you set Wake on LAN to Enabled, the computer will turn on when it receives a specific
signal from another computer on the local area network (LAN).
