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 hardware maintenance manual or direct substitutions for those FRUs can be used.

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 computer covers, unless instructed otherwise  
in the installation and configuration procedures.  
Observe the following rules when working on electrical equipment.  
© Copyright Lenovo 2011

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  
the testers.  
– 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. 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.

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 41.  
2. From the Setup Utility program main menu, select Security.  
3. Depending on the password type, select Set Power-On Password, Set Administrator Password, or  
Hard Disk Password.  
4. Follow the instructions on the right side of the screen to set, change, or delete a password.

POST error codes  
Each time you turn on your computer, it performs a series of tests to check the operation of the computer  
components and some optional devices in the computer. 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 is displayed on the screen. A single problem can cause  
several error messages. When you correct the cause of the first error message, the other error messages  
probably will not be displayed the next time you turn on the computer.

Completing the parts replacement  
After completing the installation or replacement for all parts, you need to close the computer cover and  
reconnect cables. Depending on the parts you installed or replaced, you might need to confirm the updated  
information in the Setup Utility program. Refer to Chapter 6 “Using the Setup Utility program” on page 41.  
To close the computer cover and reconnect cables to your computer, do the following:  
1. Make sure that all components have been reassembled correctly and that no tools or loose screws  
are left inside your computer. See “Locating components” on page 71 for the locations of various  
components in your computer.  
2. If you have removed the front bezel, reinstall it. See “Removing and reinstalling the front bezel” on  
page 73.  
3. Make sure that the cables are routed correctly. Keep cables clear of the hinges and sides of the  
computer chassis to avoid interference with closing the computer cover.

Chapter 10. 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  
• Secure Managed Client (some models)  
Hardware-controlled passwords  
Use the Setup Utility program to set the hardware-controlled passwords. For more information about  
passwords, see “Using passwords” on page 41.  
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 180.  
Secure Managed Client  
The Secure Managed Client (SMC) is a storage-based, desktop computing solution that helps businesses  
reduce IT costs and improve security by turning off hard disk drives and storing all data in a non-server  
remote location while offering users the flexibility and performance of a traditional desktop computer. For  
computer models that do not have an internal hard disk drive and a preinstalled operating system, but  
use a remote hard disk drive accessed through the SMC - Storage Array, contact the network or storage  
administrator.  
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

3. Levels 1 and 2 Support  
To update (flash) the BIOS, see “Updating (flashing) the BIOS from a disc” on page 180.  
Updating (flashing) the BIOS from a disc  
This section provides instructions on how to update (flash) the BIOS from a disc.  
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://www.lenovo.com/support.  
2. Do the following to locate the downloadable files for your machine type:  
a. Click Download & Drivers.  
b. In the left pane, click Downloads and drivers.  
c. From the Brand drop-down list box, select Desktops.  
d. From the Family drop-down list box, select the family name.  
e. Click Continue.  
f. From the Refine results drop-down list box, select BIOS.  
g. Click the BIOS update link.  
3. Click the TXT file that contains the instructions for updating (flashing) the BIOS from your operating  
system.  
4. Print these instructions. This is very important because these instructions will not be displayed on  
the screen after the download begins.  
5. Follow the printed instructions to download, extract, and install the update.

Recovering from a POST/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. Open the computer cover. See “Opening the computer cover” on page 72.  
3. Locate the Clear CMOS /Recovery jumper on the system board. See “Locating parts on the system  
board” on page 71.  
4. Remove any cables that impede 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. Reconnect any cables that were disconnected and reinstall the PCI card if removed.  
7. Close the computer cover and reconnect the power cords for the computer and monitor to electrical  
outlets. See “Completing the parts replacement” on page 98.  
8. Turn on the computer and then insert the POST and BIOS update (flash update) disc into the optical  
drive. The recovery session begins. The recovery session will take two to three minutes. During this  
time, you will hear a series of beeps.  
9. After the recovery session is completed, the series of beeps will end, and the system will automatically  
turn off. Remove the disc from the optical drive before the system completely turns off.  
10. Repeat step 1 through step 4.  
11. Move the Clear CMOS /Recovery jumper back to the standard position (pin 1 and pin 2).  
12. Reconnect any cables that were disconnected and reinstall the PCI card if removed.  
13. Close the computer cover and reconnect any cables that were disconnected.  
14. Turn on the computer to restart the operating system.  
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.  
Automatic 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).
