iv Hardware Replacement Guide

Overview
This guide is intended to be used by customers who are replacing Customer
Replaceable Units (CRUs) as well as trained service personnel who are replacing
Field Replaceable Units (FRUs). In this document, CRUs and FRUs will be referred
to as parts.
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.
This guide contains instructions for replacing the following parts:
Note: Use only the parts provided by Lenovo

vPower supply
vSystem board
vMicroprocessor
vHard disk drive
vDiskette drive
vOptical drive

Safety information for replacing CRUs
Do not open your computer or attempt any repair before reading the “Important
safety information” in the Quick Reference that was included with your computer.
To obtain acopy of the Quick Reference go to the World Wide Web at
http://www.lenovo.com/think/support.
Safety information for replacing FRUs
Do not open your computer or attempt any repair before reading the “Important
safety information” in the Hardware Maintenance Manual (HMM) for the computer.
To obtain acopy of the HMM,go to the World Wide Web at
http://www.lenovo.com/think/support.

Tools required
To replace some parts in your computer, you might need aflat-blade or Phillips
screwdriver.
Handling static-sensitive devices
Static electricity, although harmless to you, can seriously damage computer
components and parts.
When replacing apart, 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.
When you handle parts and other computer components, take these precautions to
avoid static-electricity damage:
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.

Chapter 2. Replacing hardware 9

9. Remove the heat sink 2 from the failing system board by pivoting the lever
1 securing the heat sink until it is fully in the up position. Carefully lift the
heat sink off of the failing system board.
Note: Place the heat sink on its side on aclean, flat surface so the thermal
interface on the bottom of the heat sink does not touch the surface and
become contaminated.
10. To remove the microprocessor from the failing system board, release the lever
3 securing the microprocessor 2 then pivot the microprocessor retainer 1
until it is fully open.
11. Use the vacuum pen 1 to remove the microprocessor from the system board
socket by lifting it out of the socket.

vacuum pen with the new microprocessor.
10 Hardware Replacement Guide

Important
Do not touch the gold contacts on the bottom of the microprocessor. If
you must touch the microprocessor, touch only the sides.
a. Take notice of the orientation of the notches 1 on the microprocessor.
This is important when installing the microprocessor on the new system
board.
b. Do not drop anything on the socket while it is open. Keep all contacts as
clean as possible.
12. On the new system board, release the lever securing the microprocessor
retainer and then pivot the retainer until it is fully open.
13. Position the microprocessor so that the notches on the microprocessor are
aligned with the tabs in the microprocessor socket.
Important
To avoid damaging the microprocessor contacts, do not tilt the
microprocessor when installing it into the socket.
14. Use the vacuum pen 1 to lower the microprocessor straight down into the
system board socket of the new system board.
Chapter 2. Replacing hardware 11

15. Lower the microprocessor retainer 1 and then lower the lever 3 to secure
the retainer. Make sure the lever is securely locked into position.
Note: There will be ablack plastic cover on the microprocessor retainer to
protect the socket on the new system board. When you lock the
microprocessor in position, remove the black plastic cover. Place the
black plastic cover on the microprocessor retainer of the failing system
board.
16. Place the heat sink 2into position and lower the lever 1 to secure the heat
sink.
