Completing the parts replacement

After completing the installation or replacement for all parts, reinstall the computer cover and reconnect the
cables.

To reinstall the computer cover and reconnect the cables to your computer, do the following:

1. Ensure that all components have been reassembled correctly and that no tools or loose screws are left

inside your computer.

2. Ensure 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 when reinstalling the computer
cover.
