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, 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 70 for the locations of various
components in your computer.
2. 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.
3. Reinstall the front bezel if you have removed it. See “Removing and reinstalling the front bezel” on
page 75.
4. Position the computer cover on the chassis so that the rail guides on the bottom of the computer cover
engage with the rails on the chassis. Then, close the computer cover to engage the cover-release button.
