This guide provides information about replacing Customer Replaceable Units
(CRUs).
This guide does not include procedures for all parts. It is expected that cables,
switches, and certain mechanical parts be replaced by trained service personnel
without the need for step-by-step procedures.
Note: Use only parts provided by Lenovo™.
This guide contains instructions for installing or replacing the following parts:
v Battery
v Heat sink
v Hard disk drive
v Optical drive
v Memory module
v System fan assembly
v AC power adapter
v Modem
v Keyboard
v Mouse
Additional information resources
If you have Internet access, the most up-to-date information for your computer is
available from the World Wide Web.
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 yourmovement.Movementcancausestaticelectricitytobuilduparound
you.
v Always handlepartsandothercomputercomponentscarefully.Handle
adapters, 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,removethenewpartfromthestatic-protectivepackaging,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.

Connector Description
USB connectors Used to attach a device that requires a Universal Serial Bus
(USB) connection, such as a USB keyboard, USB mouse, USB
scanner or USB printer. If you have more than six USB devices,
you can purchase a USB hub, which you can use to connect
additional USB devices.
Ethernet connector Used to attach an Ethernet cable for a local area network
(LAN).
Note: To operate thecomputerwithinFCCClassBlimits,use
a Category 5 Ethernet cable.
Audio-line-in connector Used to receive audio signals from an external audio device,
such as a stereo system. When you attach an external audio
device, a cable is connected between the audio line out
connector of the device and the audio line in connector of the
computer.
Audio-line-out connector Used to send audio signals from the computer to external
devices, such as powered stereo speakers (speakers with
built-in amplifiers), headphones, multimedia keyboards, or the
audio line in connector on a stereo system or other external
recording device.
Microphone connector Used to attach a microphone to your computer when you want
to record voice or other sounds on the hard disk if you use
speech-recognition software.

Chapter 3. Installing options and replacing hardware
This chapter provides an introduction to the features and options that are available
for your computer. You can expand the capabilities of your computer by adding or
replacing memory, adapters, and drives. When installing an option, use these
instructions along with the instructions that come with the option.
Attention
Do not open your computer or attempt any repair before reading the “Important safety
information” in the Safety and Warranty Guide that was included with your computer. To
obtain a copy of the Safety and Warranty Guide, go to the Support Web site at
http://www.lenovo.com/support.
Note: Use only parts provided by Lenovo.
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 adding an external option, see “Locating connectors
on the rear of your computer” on page 6 and “Locating controls and connectors on
the front of your computer” on page 5 to identify the required connector, and then
use the instructions that are included with the option to help you make the
connection and install any software or device drivers that are required for the
option.
Removing the cover
Important
Turn off the computer and wait 3 to 5 minutes to let the computer cool
before removing the computer cover.

computer. See “Locating controls and connectors on the front of your
computer” on page 5 and “Locating connectors on the rear of your computer”
on page 6.
Read “Handling static-sensitive devices” on page 4 before removing the
computer cover.
Installing memory
Your computer has two connectors for installing small outline dual inline memory
modules (SODIMMs) that provide up to a maximum of 4.0 GB of system memory.
v Use 1.8V,200-pindoubledatarate2synchronousdynamicrandomaccess
memory (DDR2 SDRAM).
v Use 256MB,512MB,1GB,or2GBmemorymodulesinanycombinationupto
memory module firmly, and pivot the memory module until it snaps into place.
Make sure that the memory module is firmly fixed in the connector and does
not move easily.
Your computer has a special type of memory that maintains the date, time, and
settings for built-in features, such as parallel-port assignments (configuration). A
battery keeps this information active when you turn off the computer.
The battery normally requires no charging or maintenance throughout its life;
however, no battery lasts forever. If the battery fails, the date, time, and
configuration information (including passwords) are lost. An error message is
displayed when you turn on the computer.
Refer to the "Lithium battery notice" in the Safety and Warranty Guide for
information about replacing and disposing of the battery.
This section provides instructions on how to replace the battery.
Note: When thecomputeristurnedonforthefirsttimeafterbattery

Chapter 5. Security features
To help prevent hardware theft and unauthorized access to your computer, several
security lock options are available. In addition to a physical lock, unauthorized use
of your computer can be prevented by a software lock that locks the keyboard
until a correct password is typed in.
Make sure that any security cables that you install do not interfere with other
computer cables.
Integrated cable lock
An integrated cable lock (sometimes referred to as the Kensington lock), can be
used to secure your computer to a desk, table, or other non-permanent fixture. The
cable lock attaches to a security slot at the rear of your computer and is operated
with a key. The cable lock also locks the buttons used to open the computer cover.
This is the same type of lock used with many laptop computers. You can order a
security cable directly from Lenovo. Go to
http://www.lenovo.com/support/ and search on Kensington.
Figure 25. Installing cable lock
Password protection
To deter unauthorized use of your computer, you can use the Setup Utility
program to set a password. When you turn on your computer, you are prompted
to type the password to unlock the keyboard for normal use.
Erasing a lost or forgotten password (clearing CMOS)
This section applies to lost or forgotten passwords. For more information about
lost or forgotten passwords, go to the ThinkVantage™ Productivity Center program.
