Replacing hardware
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.
Replacing hardware 11
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.
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.
Note Users 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
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

Replacing the coin-cell battery
Attention Do not open your computer or attempt any repairs before reading the Important
Product Information Guide.
Your computer has a special type of memory that maintains the date, time, and settings for built-
in features, such as parallel connector assignments (congurations). A coin-cell battery keeps this
information active when you turn off the computer.
The coin-cell battery normally requires no charging or maintenance throughout its life; however, no
coin-cell battery lasts forever. If the coin-cell battery fails, the date, time, and conguration information
(including passwords) are lost. An error message is displayed when you turn on the computer.
To replace the coin-cell battery,
1 Remove any media from the drives and turn off all connected devices and the computer. Then,
disconnect all power cords from electrical outlets and disconnect all cables that are connected to
the computer.
2 Remove the computer cover. For details, see  Removing the computer cover.

Attention Do not open your computer or attempt any repairs before reading the Important
Product Information Guide.
After completing the installation or replacement for all parts, reinstall the computer cover and reconnect
the cables.
To reinstall the computer cover and reconnect the cables to your computer, do the following:
1 Ensure that all components have been reassembled correctly and that no tools or loose screws are
left inside your computer.
2 Ensure that the cables are routed correctly before reinstalling the computer cover. Keep cables
clear of the hinges and sides of the computer chassis to avoid interference when reinstalling the
computer cover.
3 Install the computer cover.
4 Install the screw to secure the computer cover.
5 If a locking device is available, use it to lock the computer.
6 Reconnect the external cables and power cords to the corresponding connectors on the computer.
Replacing eld-replaceable units (FRUs) 41
Replacing eld-replaceable units (FRUs)
Before replacing FRUs
Before replacing an FRU (Field Replaceable Unit), read the following:
Only certied and trained personnel can service the computer.
Before replacing an FRU, read the entire section on replacing the part.
Be extremely careful during writing operations such as copying, saving, or formatting.
The sequence of the drives in the computer that you are servicing might have been altered. If you select an
incorrect drive, data or programs might be overwritten.
Replace an FRU only with another FRU of the correct model.
When you replace an FRU, ensure that the model of the machine and the FRU part number are correct by
referring to the website: http://www.lenovo.com/serviceparts-lookup
An FRU should not be replaced because of a single, unreproducible failure.
Single failures can occur for a variety of reasons that have nothing to do with a hardware defect, such as
cosmic radiation, electrostatic discharge, or software errors. Consider replacing an FRU only when a problem
recurs. If you suspect that an FRU is defective, clear the error log and run the test again. If the error does not
recur, do not replace the FRU.
Only replace a defective FRU.
To identify the FRU type of a computer component, see  CRUs and FRUs locations. 
Attention Do not open your computer or attempt any repairs before reading the Important
Product Information Guide.
