Supervisor password
With a Supervisor password, you can get full control of the computer. It
also can be used as a power-on password if Password on boot is set to
Enabled. Also, when you enter the BIOS Setup Utility with a Supervisor
password, you are entitled to set all of the options.
User password
If a User password is set and Password on boot is set to Enabled, a
password prompt appears when you turn on the computer.
Unauthorized users cannot get access to configuration data. You can also
use the User password to enter the BIOS Setup Utility, but only a part of
the options can be set. User password can not be set if Supervisor
password is not set.
Hard disk drive (HDD) passwords
Once an HDD password is set, you need to enter it to get access to the
hard disk. You can set the HDD password through Hard Disk Security
Setting in the BIOS Setup Utility.
Note:
If you set passwords through the BIOS Setup Utility and put your
computer into sleep mode by pressing Fn + F1, the following describes the
behavior of the computer when you bring it out of sleep mode:
You are prompted to enter the Windows log-on password rather than
the User password to resume operation.
If an HDD password is assigned to any hard disk drive, the hard disk
drive is unlocked automatically when you resume operation.
