2 Hardware Installation and Replacement Guide

Chapter 2. Overview

This guide provides information about installing or replacing Customer Replaceable Units (CRUs). However, this guide does not include procedures for all parts. It is expected that cables, switches, and certain mechanical parts be replaced by trained service personnel without the need for step-by-step procedures.

Note: Use only parts provided by Lenovo.

This guide contains instructions for installing or replacing the following parts:

v Battery

v Power supply

v Hard disk drive

v Optical drive

v Diskette drive

v Memory module

v Adapter card

v System fan assembly

v Front audio and USB assembly

v Keyboard

v Mouse

Additional information resources

If you have Internet access, the most up-to-date information for your computer is available at: http://www.lenovo.com/support

You can find:

Handling static-sensitive devices

Do not open the static-protective package containing the new part until the defective part has been removed from the computer and you are ready to install the new part. Static electricity, although harmless to you, can seriously damage computer components and parts.

When you handle parts and other computer components, take these precautions to avoid static-electricity damage:

v Limit your movement. Movement can cause static electricity to build up around

you.

v Always handle parts and other computer components carefully. Handle adapter

cards, memory modules, system boards, and microprocessors by the edges. Never touch any exposed circuitry.

v Prevent others from touching the parts and other computer components.

v Before you replace a new part, 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 in the package and your body.

v When possible, remove the new part from the static-protective packaging, 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 it.

v Do not place the part on the computer cover or other metal surface.

Replacing the battery

Your computer has a special type of memory that maintains the date, time, and settings for built-in features, such as parallel-port assignments (configuration). A battery keeps this information active when you turn off the computer.

The battery normally requires no charging or maintenance throughout its life; however, no battery lasts forever. If the battery fails, the date, time, and configuration information (including passwords) are lost. An error message is displayed when you turn on the computer.

Refer to the “Lithium battery notice” in the ThinkCentre Safety and Warranty Guide for information about replacing and disposing of the battery.

To replace the battery:

1. Remove the computer cover. See “Removing the cover” on page 11.

2. Locate the battery. See “Identifying parts on the system board” on page 9.

3. Remove the old battery.

Chapter 4. Completing the parts replacement

After replacing the parts, you need to close the cover and reconnect cables, including telephone lines and power cords. Depending on the parts replaced, you might need to confirm the updated information in the Setup Utility program. Refer to “Using the Setup Utility program” in the ThinkCentre User Guide for this product.

To replace the computer cover and connect cables to your computer:

1. Ensure that all components have been reassembled correctly and that no tools

or loose screws are left inside your computer. See “Locating components” on page 8 for the location of various components.

2. Position the computer cover on the chassis so that the rail guides on the bottom

of the computer cover engage the rails. Then, push the computer cover closed until it snaps into position.

Figure 33. Replacing the computer cover

3. If the cover is secured with thumbscrews, install them.

4. If a cover lock is installed, lock the cover.

5. Reconnect the external cables and power cords to the computer. See “Locating

connectors on the rear of your computer” on page 6.

6. To update your configuration, see “Using the Setup Utility” in the ThinkCentre

User Guide.

Note: In most areas of the world, Lenovo requires the return of the defective CRU. Information about this will come with the CRU or will come a few days after the CRU arrives.

Obtaining device drivers

You can obtain device drivers for operating systems that are not preinstalled at http://www.lenovo.com/support. Installation instructions are provided in readme files with the device-driver files.

Chapter 5. Security features

To help prevent hardware theft and unauthorized access to your computer, several security lock options are available. In addition to a physical lock, unauthorized use of your computer can be prevented by a software lock that locks the keyboard until a correct password is typed in.

Make sure that any security cables that you install do not interfere with other computer cables.

Integrated cable lock

An integrated cable lock (sometimes referred to as the Kensington lock) can be used to secure your computer to a desk, table, or other non-permanent fixture. The cable lock attaches to a security slot at the rear of your computer and is operated with a key. See Figure 34. The cable lock also locks the buttons used to open the computer cover. This is the same type of lock used with many laptop computers. You can order a security cable directly from Lenovo by searching on Kensington at: http://www.lenovo.com/support

Figure 34. Integrated cable lock

Padlock

Your computer is equipped with a padlock loop such that the cover cannot be removed when a padlock is installed.

Figure 35. Installing a padlock

Password protection

To deter unauthorized use of your computer, you can use the Setup Utility program to set a password. When you turn on your computer, you are prompted to type the password to unlock the keyboard for normal use.

What to do next:

v To work with another option, go to the appropriate section.
