Chapter 2. Installing or replacing hardware

This chapter provides instructions on how to install or replace hardware for your
computer.

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 parts and other computer 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 handle parts and other computer components carefully. Handle adapter

cards, memory modules, system boards, and microprocessors by the edges.
Never touch any 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

part to a metal expansion-slot cover or other unpainted metal surface on the
computer for at least two seconds. This reduces static electricity in the package
and your body.

v When possible, remove the new part from the static-protective packaging, and

install it directly in the computer without setting the part down. When this is
not possible, place the static-protective package that the part came in on a
smooth, level surface and place the part on it.

v 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 the capabilities of your computer by adding memory
modules, PCI cards, or drives, and maintain your computer by replacing the failing
hardware.

Notes:

1. Use only computer parts provided by Lenovo.

2. When installing or replacing an option, use the appropriate instructions in this

section along with the instructions that come with the option.

Installing external options

External speakers, a printer, or a scanner can be connected to your computer. For
some external options, you must install additional software in addition to making
the physical connection. When installing an external option, see “Locating
connectors on the front of your computer” on page 8 and “Locating connectors on
the rear of your computer” on page 9 to identify the required connector, and then
use the instructions that come with the option to help you make the connection
and install any software or device drivers that are required for the option.
