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  
© Copyright Lenovo 2011

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 centre 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 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.

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.

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 469.  
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 68.  
• 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  
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.

Chapter 6. Using the Setup Utility program  
You can use the Setup Utility program to view and change the configuration settings of your computer,  
regardless of which operating system you are using. However, the operating system settings might override  
any similar settings in the Setup Utility program.  
This chapter provides information about the following topics to help you use the Setup Utility program:  
“Using passwords” on page 43  
Starting the Setup Utility program  
To start the Setup Utility program, do the following:  
1. Make sure your computer is turned off.  
2. Repeatedly press and release the F1 key when turning on the computer. When you hear multiple  
beeps or see a logo screen, release the F1 key.  
Note: If a Power-On Password or an Administrator Password has been set, the Setup Utility program  
menu will not be displayed until you type the correct password. For more information, see “Using  
passwords” on page 43.  
When the POST detects that the hard disk drive has been removed from your computer or the memory  
module size has decreased, an error message will be displayed when you start the computer and you will be  
prompted to do one of the following:  
• Press F1 to enter the Setup Utility program.  
Note: After you enter the Setup Utility program, select Save Changes and Exit at the bottom of the  
screen. The error message will not be displayed again.  
• Press F2 to bypass the error message and log in to the operating system.  
Viewing or changing settings  
The Setup Utility program menu lists various items about the system configuration. To view or change  
settings, start the Setup Utility program. See “Starting the Setup Utility program” on page 43. Then, follow  
the instructions on the screen.  
You can use either the keyboard or the mouse to navigate through BIOS menu choices. The keys used to  
perform various tasks are displayed at the bottom of each screen.  
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  
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, or 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  
                 
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.  
Note: A password can be any combination of up to 64 alphabetic and numeric characters. For more  
information, see “Password considerations” on page 44.

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.

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.  
Figure 5. Drive bay locations

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.  
78 ThinkCentre Hardware Maintenance Manual  
         
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.  
• 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 53 “Drive bay locations” on page 120 shows the locations of the drive bays.  
Figure 53. Drive bay locations  
1 Bay 1 - Optical drive bay (with an optical drive installed)  
2 Bay 2 - Card reader drive bay  
2 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.

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  
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 469.  
Updating (flashing) the BIOS from a disc  
This section provides instructions on how to update (flash) the BIOS from a disc.  
© Copyright Lenovo 2011  
469  
                   
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 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 the computer cover. See “Removing the computer cover” on page 79.  
470 ThinkCentre Hardware Maintenance Manual  
         
3. Locate the Clear CMOS /Recovery jumper on the system board. See “Locating parts on the system  
board” on page 77.  
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. Reinstall the computer cover and reconnect the power cords for the computer and monitor to electrical  
outlets. See “Completing the parts replacement” on page 113.  
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. Reinstall 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.  
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).
