2Hardware Installation and Replacement Guide

Capitolo 2. Overview
This guide is intended to be used by customers who are installing or replacing
Customer Replaceable Units (CRUs).
This guide does not include procedures for all parts. It is expected that cables,
switches, and certain mechanical parts can be replaced by trained service personnel
without the need for step-by-step procedures.
Nota: Use only the parts provided by Lenovo™.
This guide contains instructions for installing or replacing the following parts:
vBattery
vHard disk drive
vDiskette drive
vOptical drive
vHeat sink and fan assembly
vSystem fan assembly
vMemory module
vPCI adapter card
vKeyboard
vMouse
Additional information resources
If you have Internet access, the most up-to-date information for your computer is
available from the World Wide Web.
You can find:
vCRU removal and installation instructions
vCRU removal and installation videos
vPublications
vTroubleshooting information
vParts information
vDownloads and drivers
vLinks to other useful sources of information

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:
©Lenovo 2005, 2007. Portions ©IBM Corp. 2005. 3

vLimit your movement. Movement can cause static electricity to build up around
you.
vAlways handle parts and other computer components carefully. Handle
adapters, memory modules, system boards, and microprocessors by the edges.
Never touch any exposed circuitry.
vPrevent others from touching the parts and other computer components.
vBefore you replace anew part, touch the static-protective package containing the
part to ametal 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.
vWhen 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.
vDo not place the part on the computer cover or other metal surface.

Capitolo 3. Installing options and replacing hardware
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 for

some external options, you must install additional software in addition to making
the physical connection. When adding an external option, see “Locating controls
and connectors on the front of your computer” apagina 4and “Locating
connectors on the rear of your computer” apagina 5to 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.
Removing the cover
Important
Turn off your computer and wait 3to 5minutes to let the computer cool
before removing the computer cover.

3. In some models, you might have to remove the PCI adapter in order to gain
access to the battery.
4. Slide the drive bay assembly forward until the drive bay assembly is aligned
with the two slots on the sides of the chassis and remove the drive cables from
the system board. Then pull upward on the handle 1 to remove the drive bay
assembly completely from the computer.
Installing internal options
Important
Read “Handling static-sensitive devices” apagina 3before opening the
computer cover.
Installing memory
Your computer has two connectors for installing double date rate 2dual inline
memory modules (DDR2 DIMMs) that provide up to amaximum of 4.0 GB of
system memory.
When installing memory modules, the following rules apply:
Figura 7. Removing the PCI adapter
Figura 8. Removing the drive bay assembly
Capitolo 3. Installing options and replacing hardware 11

vUse 1.8 V, 240-pin, double data rate 2synchronous dynamic random access
memory (DDR2 SDRAM).
vUse 256 MB, 512 MB, 1GB, or 2GB memory modules in any combination up to
amaximum of 4.0 GB.
Nota: Only DDR2 SDRAM DIMMs can be used.
To install amemory module:
1. Remove the computer cover. See “Removing the cover” apagina 9.
2. You might have to remove the drive bay assembly to access the memory
connectors. See “Accessing system board components and drives” apagina 10.
3. Remove any parts that might prevent access to the memory connectors.
4. Locate the memory connectors. See Figura 4apagina 7.
