Chapter 3. Tips on using the computer

This chapter provides tips on using the computer.

Attaching a Kensington-style cable lock

You can use a Kensington-style cable lock to secure your computer to a desk, table, or other 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:

http://www.lenovo.com/support

Figure 5. Attaching a Kensington-style cable lock

Installing the computer into the TIO monitor

1. For the Tiny-in-One 23 monitor (MT: 10DQ), remove the rear Wi-Fi antenna cover before installing the

computer. See “Replacing the Wi-Fi antennas” on page 44.

2. Connect the computer either to the power adapter shipped with the TIO monitor or to the adapter

shipped with the computer that has higher power rating.

10 M920q User Guide and Hardware Maintenance Manual

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,

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

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 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:

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 (configurations). A coin-cell battery keeps this information active

when you turn off the computer.

Chapter 4.Replacing hardware 35

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 configuration information (including

passwords) are lost. An error message is displayed when you turn on the computer.
