Chapter 2. Overview  
This guide provides information about installing and 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

Note: Use only parts provided by Lenovo.  
This guide contains instructions for installing and or replacing the following parts:  
v Battery  
v Power supply  
v Heat sink and fan assembly

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.

Connector  
Description  
USB connector  
Used to attach a device that requires a Universal Serial Bus  
(USB) connector, such as a USB keyboard, a USB mouse, a USB  
scanner, or a USB printer. If you have more than eight USB  
devices, you can purchase a USB hub, which you can use to  
connect additional USB devices.  
Ethernet connector

Note: To operate the computer within FCC Class B limits, use a  
Category 5 Ethernet cable.  
Serial port  
Used to attach an external modem, a serial printer, or other  
devices that use a 9-pin serial port.  
Audio line-in connector  
Used to receive audio signals from an external audio device,  
such as a stereo system. When you attach an external audio  
device, a cable is connected between the audio line-out  
connector of the device and the audio line-in connector of the  
computer.  
Audio line-out connector Used to send audio signals from the computer to external  
devices, such as powered stereo speakers (speakers with built-in  
amplifiers), headphones, multimedia keyboards, or the audio  
line-in connector on a stereo system or other external recording  
devices.  
eSATA connector  
Use this external Serial Advanced Technology Attachment  
(eSATA) connector to attach an external hard disk drive.  
DisplayPort connector  
Used to attach a high-performance monitor, a direct-drive  
monitor, or other devices that use a DisplayPort connector.  
Standard mouse connector Used to attach a mouse, a trackball, or other pointing devices  
that use a standard mouse connector.  
Standard keyboard

Installing internal drives  
This section provides information and instructions for installing internal drives.  
Internal drives are devices that your computer uses to read and store data. You can  
add drives to your computer to increase storage capacity and to enable your  
computer to read other types of media. Some of the types of drives that are  
available for your computer are:  
v Serial Advanced Technology Attachment (SATA) hard disk drives  
v SATA optical drives, such as CD drives or DVD drives  
v Removable media drives  
Note: These types of drives are also referred to as integrated drive electronics  
(IDE) drives.  
Internal drives are installed in bays. In this book, the bays are referred to as bay 1  
and bay 2.  
When you install an internal drive, it is important to note the type and size of the  
drive that you can install in each bay. Also, it is important to correctly connect the  
internal drive cables to the installed drive.

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. Open the computer cover. See “Opening the cover” on page 12.  
4. Remove the old battery.

Chapter 4. Completing the parts replacement  
After completing all parts replacements, you need to close the cover and reconnect  
cables, such as 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” in the ThinkCentre User Guide for this product.  
To complete the parts replacement:  
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. Make sure that the cables are routed correctly before lowering the drive bay  
assembly.  
Important  
Correctly route all power supply cables to avoid interference with the  
drive bay assembly. Keep cables clear of the hinges and sides of the  
computer chassis.

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. 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. You can order a security cable directly from  
Lenovo by searching on Kensington at:
