Completing the parts replacement

After completing the installation or replacement for all parts, you need to reinstall the computer cover
and reconnect cables.
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 102 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 108.
4. If you have removed the front bezel, reinstall it. See "Removing and reinstalling the front bezel" on
page 107.
5. Position the computer cover on the chassis so that the rail guides on the computer cover engage the
rails on the chassis. Then, slide the computer cover to the front of the computer until it snaps into
position and is closed. Then, install the two screws to secure the computer cover.
