Chapter 2. Using Your Computer
Make sure that only authorized individuals access your computer. Establishing different
kinds of passwords requires that other possible users know the proper passwords in
order to access your computer or your data.
As many as three passwords might be needed for your computer: the Supervisor
password, the User password, and the Hard disk drive (HDD) password. When the
Supervisor password is set, only the Supervisor password entitles you full control of the
computer.
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 Check is set to Always. 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 Check is set to Always, 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 cannot 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.
To set a Supervisor Password:
Only a system administrator will be able to perform this procedure.
