Replacing hardware

Before replacing hardware

Attention

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 Customer Replaceable Units (CRUs).

Information about this will come with the CRU or will come a few days after the CRU arrives.

Do not open your computer or attempt any repairs before reading the Important Product Information Guide.

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 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 anti-static package containing the component 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 component.

• When possible, remove the new component from the anti-static package, and install it directly in the

computer without setting the part down. When this is not possible, place the anti-static package that the

component came in on a smooth, level surface and place the component on the package.

• Do not place the component on the computer cover or any 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

Note

Optional-service CRUs

Users are responsible for replacing all self-service CRUs.

You can install self-service CRUs easily. These CRUs might be standalone,

latched, or secured by up to two screws.

Examples of self-service CRUs include the keyboard, mouse, any USB device, and the power cord. Other self-service CRUs might include memory

modules, adapter cards, hard disk drives, and optical drives.

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 concealed by an access panel that is secured by more than two screws. You

must remove the screws and panel to access the specic CRU.

Optional-service CRUs can be removed and installed by users or, during the

warranty period, by a Lenovo service technician.

Field-Replaceable Units (FRUs)

FRUs are computer parts that a trained technician can upgrade or replace.

For detailed FRU information, such as the FRU part numbers and supported computer models, go to: http://www.lenovo.com/serviceparts-lookup
