Adding the Power-on Password

The power-on password is provided to protect your computer from unauthorized access.

There are two types of the power-on password: machine password and user password. The machine password is provided

for users with administrator rights on the computer to change all the setup options in the BIOS setup screen, as well as to

start the computer. The user password is provided for the standard users to allow for changing some of the BIOS setup

options, as well as starting the computer. To set the user password, you must first set the machine password.
