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 76 for the locations of various
components in your computer.

page 80.
3. 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.
