Chapter 3. Computer locks
Attaching a Kensington-style cable lock
You can use a Kensington-style cable lock to secure your computer to a desk, table, or another
nonpermanent fixture. The cable lock connects to the security-lock slot at the rear of your computer.
Depending on the type selected, the cable lock can be operated with a key or combination. The cable lock
also locks the buttons used to open the computer cover. This is the same type of lock used with many
notebook computers. You can order such a cable lock directly from Lenovo by searching for Kensington at:

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:
http://www.lenovo.com/serviceparts-lookup
• 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,
and 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
© Copyright Lenovo 2020 13
concealed by an access panel that is secured by more than two screws. You must remove the screws
and panel to access the specific CRU. Optional-service CRUs can be removed and installed by users
or, during the warranty period, by a Lenovo service technician.
Before replacing FRUs
Before replacing any FRU, read the following:
• Only certified and trained personnel can service the computer.
• Before replacing an FRU, read the entire section about 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.
• 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.
Locating FRUs (including CRUs)
Notes:
• Some of the following components are optional.
• To replace a component that is not in the list below, contact a Lenovo service technician. For a list of
Lenovo Support phone numbers, go to:
