If you have removed the front bezel, reinstall it. See “Removing and
reinstalling the front bezel” on page 89.

cover. Keep cables clear of the hinges and sides of the computer chassis to
avoid interference with reinstalling the computer cover.

6.
If there is a padlock available, lock the computer cover.
