Locking the keyboard
you can lock the keyboard so that others are unable to use it. if a user password is set using the configuration/setup utility program, the keyboard is locked when you turn on the computer. you must type the password before the keyboard will unlock.
you can enable the user password feature with the configuration/setup utility program see “using passwords” on page 24.
some operating systems have a keyboard and mouse lock-up feature. see the documentation that comes with your operating system for more information.
