Completing the parts replacement
After completing the installation or replacement for all parts, you need to reinstall the computer cover

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 8 for the locations of the various
components in your computer.
2. Make sure that all the internal cables are routed properly to avoid interference with lowering the drive bay
assembly and closing the computer cover. Keep the cables clear of the hinges and sides of the chassis.
3. Lower the drive bay assembly. See “Accessing the system board components and drives” on page 14.
4. If you have removed the front bezel, reinstall it.
