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.  
Installing or replacing hardware  
This section provides instructions on how to install or replace hardware for your computer. You can expand

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
