Hardware Replacement Guide

Replacing the External speaker

1. Remove any media (diskettes, CDs, or memory cards) from the drives, shut

down the computer, and turn off all attached devices.

2. Unplug all power cords from electrical outlets.

3. Locate the Speaker. Refer to “Locating connectors on the rear of the

computer” and “Locating connectors on the front of the computer”. Your

speaker might be connected to the Audio connector to an Audio connector

at either the front or rear of the computer. Locate the connector for the

speaker.

4. Disconnect the failing speaker cable from the computer and connect the new

speaker cable to the same connector.

Completing the installation

After replacing the parts, you need to close the computer cover and reconnect

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. Refer to “Starting the Setup Utility” in the

User Guide or in the

Hardware Maintenance Manual.

To complete the part installation:

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

or loose screws are left inside your computer. Refer to “Locating components”

for the location of the various components.

2. Make sure that the cables are routed correctly before installing the computer

cover.

3. 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.
