Chapter 2. Installing or replacing hardware  
This chapter provides instructions on how to install or replace hardware for your computer.  
This chapter contains the following topics:  
“Handling static-sensitive devices” on page 13  
“Obtaining device drivers” on page 44  
“Basic security features” on page 44  
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.  
• 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.

operates independently from the Windows operating system. This enables you to perform recovery  
operations even if you cannot start the Windows operating system. You can perform the following recovery  
operations from the Rescue and Recovery workspace:  
• Rescue files from your hard disk drive or from a backup The Rescue and Recovery workspace enables  
you to locate files on your hard disk drive and transfer them to a network drive or other recordable media,  
such as a USB device or a disc. This solution is available even if you did not back up your files or if  
changes were made to the files since your last backup operation. You can also rescue individual files from  
a Rescue and Recovery backup located on your local hard disk drive, a USB device, or a network drive.  
• Restore your hard disk drive from a Rescue and Recovery backup If you have backed up your hard disk  
drive using the Rescue and Recovery program, you can restore the hard disk drive from a Rescue and  
Recovery backup, even if you cannot start the Windows operating system.

you to restore the complete contents of your hard disk drive to the factory default settings. If you have  
multiple partitions on your hard disk drive, you have the option to restore the factory default settings to the  
C: partition and leave the other partitions intact. Because the Rescue and Recovery workspace operates  
independently from the Windows operating system, you can restore the factory default settings even if  
you cannot start the Windows operating system.  
Attention: If you restore the hard disk drive from a Rescue and Recovery backup or restore the hard disk  
drive to the factory default settings, all files on the primary hard disk drive partition (usually drive C:) will be  
deleted in the recovery process. If possible, make copies of important files. If you are unable to start the  
Windows operating system, you can use the rescue files feature of the Rescue and Recovery workspace to  
copy files from your hard disk drive to other media.

Chapter 5. Updating system programs  
This chapter provides information about updating the POST and BIOS, and how to recover from a POST  
and BIOS update failure.  
This chapter contains the following topics:  
Using system programs  
System programs are the basic layer of software built into your computer. System programs include the  
POST, the BIOS, and the Setup Utility program. The POST is a set of tests and procedures that are  
performed each time you turn on your computer. The BIOS is a layer of software that translates instructions  
from other layers of software into electrical signals that the computer hardware can execute. You can use  
the Setup Utility program to view or change the configuration settings of your computer. See Chapter 4  
“Using the Setup Utility program” on page 55 for detailed information.  
Your computer system board has a module called electrically erasable programmable read-only memory  
(EEPROM, also referred to as flash memory). You can easily update the POST, the BIOS, and the Setup  
Utility program by starting your computer with a system-program-update disc or running a special update  
program from your operating system.  
Lenovo might make changes and enhancements to the POST and BIOS. When updates are released, they  
the POST and BIOS updates are available in a TXT file that is included with the update files. For most  
models, you can download either an update program to create a system-program-update disc or an update  
program that can be run from the operating system.  
Updating (flashing) the BIOS from a disc  
This section provides instructions on how to update (flash) the BIOS from a disc.

Verify that:  
• The computer is turned on.  
• The mouse is correctly connected to an appropriate mouse connector (the PS/2

The computer beeps multiple  
times before the operating  
system starts.  
Verify that no keys are stuck.  
Diagnostic programs  
Diagnostic programs are used to test hardware components of your computer. Diagnostic programs can  
also report operating-system-controlled settings that interfere with the correct operation of your system. You  
can use the preinstalled Lenovo ThinkVantage Toolbox program to diagnose computer problems, if your  
computer is running the Windows operating system.  
Notes:  
See “PC-Doctor for DOS” on page 64 for detailed information.  
2. If you are unable to isolate and repair the problem yourself after running the programs, save and print  
the log files created by the programs. You will need the log files when you speak to a Lenovo technical  
support representative.  
Lenovo ThinkVantage Toolbox  
The Lenovo ThinkVantage Toolbox program helps you maintain your computer, improve computing security,  
diagnose computer problems, get familiar with the innovative technologies provided by Lenovo, and get  
more information about your computer. You can use the diagnostics feature of the Lenovo ThinkVantage  
Toolbox program to test devices, diagnose computer problems, create bootable diagnostic media, update  
system drivers, and view system information.  
To run the Lenovo ThinkVantage Toolbox program on the Windows 7 operating system, click Start All  
Programs Lenovo ThinkVantage Tools System Health and Diagnostics. Follow the instructions on  
the screen.  
For additional information about running the Lenovo ThinkVantage Toolbox program, refer to the Lenovo  
ThinkVantage Toolbox help system.

You can also download the latest version of the PC-Doctor for DOS diagnostic program from  
http://www.lenovo.com/support. The PC-Doctor for DOS diagnostic program runs independently of the  
Windows operating system. Use the PC-Doctor for DOS diagnostic program if you are unable to start the  
Windows operating system. You can run the PC-Doctor for DOS diagnostic program from a diagnostic  
disc that you created.  
Creating a diagnostic disc  
This section provides instructions on how to create a diagnostic disc.  
64 ThinkCentre User Guide  
           
To create a diagnostic disc, do the following:  
1. Download a self-starting bootable disc image (known as an ISO image) of the diagnostic program from:  
2. Use any disc burning software to create a diagnostic disc with the ISO image.  
Running the diagnostic program from the diagnostic disc  
This section provides instructions on how to run the diagnostic program from the diagnostic disc that  
you created.  
To run the diagnostic program from the diagnostic disc that you created, do the following:  
1. Make sure your computer is turned off.  
2. Repeatedly press and release the F12 key when turning on the computer. When the Startup Device  
Menu opens, release the F12 key.  
3. Insert the diagnostic disc into the optical drive.  
4. Select the optical drive with the diagnostic disc as the startup device and press Enter. The diagnostic  
program opens.  
5. Follow the instructions on the screen to run the desired diagnostic test. For additional help, press

Cleaning an optical mouse  
This section provides instructions on how to clean an optical mouse.  
An optical mouse uses a light-emitting diode and an optical sensor to navigate the pointer. If the pointer on  
the screen does not move smoothly with the optical mouse, you might need to clean the mouse.  
To clean an optical mouse, do the following:  
1. Turn off your computer.  
2. Disconnect the mouse cable from the computer.  
3. Turn the mouse upside down to check the lens.  
a. If there is a smudge on the lens, gently clean the area with a plain cotton-tipped swab.  
b. If there is debris in the lens, gently blow the debris away from the area.  
4. Check the surface on which you are using the mouse. If you have a very intricate picture or pattern  
beneath the mouse, it may be difficult for the digital signal processor (DSP) to determine changes  
in the mouse position.  
5. Reconnect the mouse cable to the computer.  
6. Turn your computer back on.

Service methods and procedures vary by country, and some services might not be available in all countries.  
International Warranty Service is delivered through the method of service (such as depot, carry-in, or  
on-site service) that is provided in the servicing country. Service centers in certain countries might not be  
able to service all models of a particular machine type. In some countries, fees and restrictions might  
apply at the time of service.
