Chapter 5. 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 the Important Product Information
Guide.
Read these notes before replacing hardware:
• Some of the hardware components explained in this manual are optional.
• 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 (Customer Replaceable Units).
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 component until the defective component has
been removed and you are ready to install the new component. Static electricity, although harmless to you,
can seriously damage computer components.
When you handle parts and other computer components, take these precautions to avoid static damage:
• Limit your movement. Movement can cause static electricity to build up around you.
• Always handle parts and other computer components carefully. Handle PCI/PCI-Express cards, memory
modules, system boards, and microprocessors by the edges. Never touch any exposed circuitry.
• Prevent others from touching the parts 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
that the part came in 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 replaceable parts
Customer-Replaceable Units (CRUs)
CRUs are computer parts that a user can upgrade or replace. There are two types of CRUs: self-service and
optional-service.
• Self-service CRUs:
You can install self-service CRUs easily. These CRUs might be standalone, latched, or secured by up to
two screws.
