Secure Mode

Secure mode secures the system against unauthorized use. Secure mode inhibits keyboard and mouse input, and disables the power switch and reset button. Secure mode takes effect when the keyboard and mouse remain inactive for an amount of time that you determine. You can gain access to the system only after you enter the correct user password.

Note: You must set a user password before you can enable secure mode.

Refer to the following table for information on the options available for the secure mode.
