Computer locks
Locking the computer cover
Locking the computer cover helps prevent unauthorized access to
the inside of your computer. Your computer features a padlock loop
so that the computer cover cannot be removed when a padlock is
installed.
Attaching a Kensington-style cable lock
Attaching a cable lock
You can use a Kensington-style cable lock to secure your computer
to a desk, table, or other nonpermanent xture. 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: http://www.lenovo.com/
support.
A cable lock can be used to secure devices, such as the keyboard and
the mouse, by locking the device cables to the computer. The cable
lock connects to the cable-lock slots on the rear of the computer.
To install a cable lock, do the following:
1
Insert the clip 1 into the cable-lock slot 4.

Computer locks 11
Guide the cables you want to lock into the grooves of the cable
lock.
Press the clip 2 into the cable-lock slot 3 until it snaps into
position.
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 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 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
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 specic 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:
