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.
© Lenovo 2005, 2008. Portions © IBM Corp. 2005. 3
Page 12
Locations
Locating controls and connectors on the front of your computer
v Always handle parts and other computer components carefully. Handle
adapters, 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.
This chapter provides illustrations to help locate the various connectors, controls
and components of the computer. To remove the computer cover, see “Removing
the cover” on page 9.

audio line in connector on a stereo system or other external
recording device.
USB connectors Used to attach a device that requires a Universal Serial Bus
(USB) connection, such as a USB keyboard, USB mouse, USB
scanner or USB printer. If you have more than six USB devices,
you can purchase a USB hub, which you can use to connect
additional USB devices.
Serial connector Used to attach an external modem, serial printer, or other
devices that use a 9-pin serial connector.

Installing internal drives
This section provides information and instructions for installing and removing
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 different drives that are
available for your computer are:
v Serial Advanced Technology Attachment ( S ATA ) hard disk drives
v Parallel ATA hard disk drives
v Optical drives, such as CD drives or DVD drives
v Removable media drives
These different drives are also referred to as integrated drive electronics
Note:
(IDE) drives.
Internal drives are installed in bays. In this book, the bays are referred to as bay 1,
bay 2, and so on.
When you install an internal drive, it is important to note what type and size of
drive that you can install in each bay. Also, it is important to correctly connect the
internal drive cables to the installed drive.
Drive specifications
Your computer comes with the following factory-installed drives:
v An optical drive in bay 1 (some models)
v A 3.5-inch hard disk drive in bay 2
v A 3.5-inch diskette drive in bay 3 (some models)

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 Safety and Warranty Guide for
information about replacing and disposing of the battery.
To change the battery:
1. Turn off the computer and disconnect the power cord from the electrical outlet
and from the computer.
2. Remove the computer cover. See “Removing the cover” on page 9.
3. Yo u might have to access the system board components. See “Accessing system
board components and drives” on page 10.
4. Locate the battery. See Figure 3 on page 7.
5. Remove the old battery.
Figure 20. Battery removal
6. Install the new battery.
Figure 21. Battery installation
7. Replace the computer cover, and connect the cables. See Chapter 4,
8. Turn on the computer and all attached devices.
9. Use the Setup Utility program to set the date and time and any passwords. See
“Completing the parts replacement,” on page 33.
Note: When the computer is turned on for the first time after battery
replacement, an error message might be displayed. This is normal after
replacing the battery.

Chapter 4. Completing the parts replacement
After working with parts, you need to replace the computer cover and reconnect
any cables, including telephone lines and power cords. Also, depending on the
part that was replaced, you might need to confirm the updated information in the
Setup Utility program.
This section provides instructions on how 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.
2. Reposition any cables that might impede the replacement of the computer
cover.
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.
3. If the drive bay assembly was removed, align it with the two slots and rails on
the sides of the chassis and reconnect the drive cables to the system board.
4. Slide the drive bay assembly towards the rear of the chassis until it snaps into
position.
5. Reinstall the front bezel if it was removed.
6. Position the computer cover on the chassis so that the rail guides on the sides
of the cover engage the rails and push the cover to the closed position until it
snaps into position. If your computer has screws to secure the computer cover,
install the screws.
Figure 39. Replacing the cover
7. Install any locking devices such as a padlock as necessary.
8. Reconnect the external cables and power cords to the computer. See “Locating
connectors on the rear of your computer” on page 5.

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 you install do not interfere with other computer
cables.
Integrated cable lock
With an integrated cable lock (sometimes referred to as the Kensington lock), you
can 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. Go to http://www.lenovo.com/support/ and
search on Kensington.

Padlock
Your computer is equipped with a padlock loop such that the cover cannot be
removed when a padlock is installed.
Figure 41. Padlock loop
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.
