Chapter 3. Computer locks
This chapter provides instructions on how to lock your computer with the locking devices to keep your

Locking the computer cover helps prevent unauthorized access to the inside of your computer. Your
computer features a padlock loop so that the computer cover cannot be removed when a padlock is
installed.
