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 7 "Using the Setup Utility program" on page 67.
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 11 for the locations of various
components in your computer.
2. Make sure that the cables are routed correctly. Keep cables clear of the hinges and sides of the
computer chassis to avoid interference with closing the computer cover.
3. Lower the drive bay assembly. See "Accessing the system board components and drives" on page 32.
4. If you have removed the front bezel, reinstall it.
