Advanced Menu

Security Menu

The BIOS Setup program allows the user to specify passwords in the Security menu. The passwords control access to the BIOS and certain Security menu options during system startup. The passwords are not case sensitive. In other words, it makes no difference whether you enter a password using upper or lowercase letters. The BIOS Setup program allows the user to specify two separate passwords: a “Supervisor” password and a “User” password. When disabled, anyone may access all BIOS Setup program functions. When enabled, the Supervisor password is required for entering the BIOS Setup program and having full access to all Security menu options.

Change Supervisor/User Password
When you select this function, a message box will appear on the screen that says [Enter New Password]

Type the password you want, up to six characters in length and press [Enter]. The password typed now will replace any previously set password from the CMOS memory. You may also press [ESC] to abort the selection and not enter a password.

When the Supervisor Password is set, User Access Level and Password Check will be shown on the menu. You can make further settings of access rights in the User Access Level item. Setting options: No Access, View Only, Limited and Full Access. The Password Check item is used to specify the type of BIOS password protection that is implemented. Settings are described below:

Setup The password prompt appears only when the user tries to run Setup.
Always A password prompt appears every time when the notebook is powered on or when the user tries to run Setup.

To clear a set password, just press [Enter] when you are prompted to enter the password. A message box will show up confirming the password will be disabled. Once the password is disabled, the system will boot and you can enter Setup without entering any password
