Three password types protect your computer from unauthorized access. Setting these passwords creates several different levels of protection for your computer and data: 6 Setup Password prevents unauthorized entry to the BIOS Utility. Once set, you must key-in this password to gain access to the BIOS Utility. 6 Power-On Password secures your computer against unauthorized use. Combine the use of this password with password checkpoints on boot-up and resume from hibernation for maximum security. 6 Hard Disk Password protects your data by preventing unauthorized access to your hard disk. Even if the hard disk is removed from the computer and moved to another computer, it cannot be accessed without the Hard Disk Password. When a password is set, a password prompt appears on the left-hand corner of the display screen. 1. When the Setup Password is set, the following prompt appears when you press F2 to enter the BIOS Utility at boot-up. Type the Setup Password and press Enter to access the BIOS Utility. 2.
