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 replacing 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.
