The Administrator Password prevents unauthorized access to the BIOS Setup
options. Once the administrator password is set, the BIOS setup options can only
be modified after providing the correct password.
The following rules and dependencies apply to the Administrator Password -
● The administrator password cannot be set if computer and/or internal hard
drive passwords are previously set.
● The administrator password can be used in place of the computer and/or
internal hard drive passwords.
● When set, the administrator password must be provided during a firmware
update.
● Clearing the administrator password also clears the computer password (if
set).
Dell Technologies recommends using an administrator password to prevent
unauthorized changes to BIOS setup options.
The System Password prevents the computer from booting to an operating
system without entering the correct password.
The following rules and dependencies apply when the System Password is used -
● The computer shuts down when idle for approximately 10 minutes at the
computer password prompt.
● The computer shuts down after three incorrect attempts to enter the
computer password.
● The computer shuts down when the Esc key is pressed at the System
Password prompt.
● The computer password is not prompted when the computer resumes from
standby mode.
Dell Technologies recommends using the computer password in situations where
it is likely that a computer may be lost or stolen.
The Hard Drive Password can be set to prevent unauthorized access of the data
stored on the hard drive. The computer prompts for the hard drive password
during boot in order to unlock the drive. A password-secured hard drive stays
locked even when removed from the computer or placed into another computer.
It prevents an attacker from accessing data on the drive without authorization.
The following rules and dependencies apply when the Hard Drive Password is
used -
● The hard drive password option cannot be accessed when a hard drive is
disabled in the BIOS setup.
● The computer shuts down when idle for approximately 10 minutes at the hard
drive password prompt.
● The computer shuts down after three incorrect attempts to enter the hard
drive password and treats the hard drive as not available.
● The hard drive does not accept password unlock attempts after five incorrect
attempts to enter the hard drive password from the BIOS Setup. The hard
drive password must be reset for the new password unlock attempts.
● The computer treats the hard drive as not available when the Esc key is
pressed at the hard drive password prompt.
● The hard drive password is not prompted when the computer resumes from
standby mode. When the hard drive is unlocked by the user before the
computer goes into standby mode, it remains unlocked after the computer
resumes from standby mode.
● If the computer and hard drive passwords are set to the same value, the hard
drive unlocks after the correct computer password is entered.
