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

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.

Connector Description

Standard mouse connector Used to attach a mouse, trackball, or other pointing device that

uses a standard mouse connector.

Standard keyboard
connector

Used to attach a keyboard that uses a standard keyboard
connector.

Serial connector Used to attach an external modem, serial printer, or other

devices that use a 9-pin serial connector.

Parallel connector Used to attach a parallel printer, parallel scanner, or other

devices that use a 25-pin parallel connector.

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.

Ethernet connector Used to attach an Ethernet cable for a local area network

(LAN).
Note: To operate the computer within FCC Class B limits, use
a Category 5 Ethernet cable.

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 device.

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.

Chapter 3. Installing options and replacing hardware

This chapter provides an introduction to the features and options that are available
for your computer. You can expand the capabilities of your computer by adding
memory, adapters, or drives. When installing an option, use these instructions
along with the instructions that come with the option.

Attention

Do not open your computer or attempt any repair before reading the “Important safety
information” in the Safety and Warranty Guide that was included with your computer. To
obtain a copy of the Safety and Warranty Guide, go to the Support Web site at
http://www.lenovo.com/support.

Note: Use only parts provided by Lenovo.

Installing external options

External speakers, a printer, or a scanner can be connected to your computer. For
some external options, you must install additional software in addition to making
the physical connection. When adding an external option, see “Locating connectors
on the rear of your computer” on page 6 and “Locating controls and connectors on
the front of your computer” on page 5 to identify the required connector, and then
use the instructions that are included with the option to help you make the
connection and install any software or device drivers that are required for the
option.
