Completing the parts replacement
After completing the installation or replacement for all parts, you need to reinstall the computer cover and
reconnect cables. Depending on the parts you installed or replaced, you might need to confirm the updated
information in the Setup Utility program. Refer to Chapter 6 “Using the Setup Utility program” on page 37.
To reinstall the computer cover and reconnect cables to your computer, do the following:
1. Make sure that all components have been reassembled correctly and that no tools or loose screws
are left inside your computer. See “Locating components” on page 65 for the locations of various
components in your computer.
2. If you have removed the front bezel, reinstall it. See “Removing and reinstalling the front bezel” on
page 68.
3. Make sure that the cables are routed correctly before reinstalling the computer cover. Keep cables clear
of the hinges and sides of the computer chassis to avoid interference with reinstalling the computer cover.
4. Position the computer cover on the chassis so that the rail guides on the bottom of the computer
cover engage the rails on the chassis. Then, push the cover to the front of the computer until it snaps
into position.
