Using the Passwords
Using the Hard-Disk and Power-On Passwords
You can use a hard-disk password with a power-on password.
When you turn on the computer, you are prompted to enter first the
power-on password and then the hard-disk password.
The hard-disk password can be the same as the power-on password.
If both passwords are the same:
You are prompted only once with the power-on password prompt
when the computer is turned on. Both passwords are changed
or removed at the power-on password prompt.
The resume function caused by the timer or an incoming call can
be used. The hard-disk password prompt will not appear when
normal operation is activated from the suspend mode by the
timer or an incoming call. Enter the hard-disk password at the
blank screen. The LCD remains blank until the correct password
is entered.
Using the Supervisor and Hard-Disk Passwords
When a supervisor password is set, the same password is
automatically set for the hard-disk password. Before setting a
supervisor password, make sure that you do not have a hard-disk
password set. If you do, removed it.
When you change or remove the supervisor password, the hard-disk
password also is changed or removed. Even though a hard-disk
password is set by the supervisor password, you are not prompted to
enter the hard-disk password when the computer is turned on; you
cannot change or remove the hard-disk password set by the
supervisor password.
