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  
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:  
v Limit your movement. Movement can cause static electricity to build up around  
you.  
v 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.  
v Prevent others from touching the parts and other computer components.  
v 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.  
v 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.  
v Do not place the part on the computer cover or other metal surface.  
Installing or replacing hardware

This chapter contains the following topics:  
Notes:  
1. There are a variety of methods to choose from when considering how to  
recover in the event of a software- or hardware-related problem. Some methods  
vary depending on the type of your operating system.  
2. The product on the recovery media may be used only for the following  
purposes:  
v Restore the product preinstalled on your computer  
v Reinstall the product  
v Modify the product using the Additional Files  
Creating and using recovery media  
You can use recovery media to restore the hard disk drive to the factory default  
settings. Recovery media are useful if you transfer the computer to another area,  
sell the computer, recycle the computer, or put the computer in an operational state  
after all other methods of recovery have failed. As a precautionary measure, it is  
important to create recovery media as early as possible.  
Note: The recovery operations you can perform using recovery media vary  
depending on the operating system from which the recovery media were  
created. The recovery media might contain a boot medium and a data  
medium. Your Microsoft Windows license permits you to create only one  
data medium, so it is important that you store the recovery media in a safe  
place after you have made them.  
Creating recovery media  
This section provides instructions on how to create recovery media on different  
operating systems.  
Note: On the Windows 7 operating system, you can create recovery media using  
discs or external USB storage devices. On the Windows Vista and Windows  
XP operating systems, you can create recovery media using only discs, so  
this operation is also called creating Product Recovery discs.″

from the Rescue and Recovery workspace:  
v 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.  
v Restore your hard disk drive from a Rescue and Recovery backup

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  
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 are available as downloadable files on the Lenovo Web  
site at http://www.lenovo.com. Instructions for using 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.  
Note: You can download a self-starting bootable disc image (known as an ISO
