Chapter 4. Replacing hardware
This chapter provides instructions on how to replace hardware for your computer.
Before replacing hardware
Attention:
Do not open your computer or attempt any repairs before reading this section and the
Important
Product Information Guide

Notes before replacing hardware
• Use computer components provided only by Lenovo.
• When installing or replacing an option, use the appropriate instructions explained in this manual along with
the instructions that come with the option.
• In most areas of the world, Lenovo requires the return of defective CRUs. Information about this will come
with the CRU or will come a few days after the CRU arrives.
Handling static-sensitive devices
Do not open the static-protective package containing the new part until the defective part has been removed
and you are ready to install the new part. Static electricity, although harmless to you, can seriously damage
computer components and options.
When you handle options and other computer components, take these precautions to avoid static-electricity
damage:
• Limit your movement. Movement can cause static electricity to build up around you.
• Always handle options and other computer components carefully. Handle PCI/PCIe cards, memory
modules, system boards, and microprocessors by the edges. Never touch any exposed circuitry.
• Prevent others from touching the options and other computer components.
• 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 from the
package and your body before you install or replace a new part.
• When possible, remove the new part from the static-protective package, and install it directly in the
computer without setting the part down. When this is not possible, place the static-protective package on
a smooth, level surface and place the part on the package.
• Do not place the part on the computer cover or other metal surface.
Knowing FRUs (including CRUs)
• Field Replaceable Units (FRUs) are computer parts that a trained technician can upgrade or replace. FRUs
include all CRUs. For detailed FRU information, such as the FRU part numbers and supported computer
models, go to:

• Customer Replaceable Units (CRUs) are computer parts that a user can upgrade or replace.
– Self-service CRUs: You can install self-service CRUs easily. These CRUs might be stand-alone,
latched, or secured by up to two screws. Examples of self-service CRUs include the keyboard, mouse,
any USB device. You are responsible for replacing all self-service CRUs.
– Optional-service CRUs: Handling optional-service CRUs requires some technical skills and simple tools
(such as a screwdriver). These CRUs are isolated parts within the computer. They are usually
