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.
!
Once you have set the power-on password, you cannot start your computer without entering the password. Make sure not to forget the password. Write
down your password and keep it safe and private from other people.
If you forget the power-on password and need assistance to reset it, a password reset fee will be charged, and your computer may need to be sent in
for depot service for password reset.
✍
If your computer is equipped with the fingerprint sensor and you have set the power-on password in conjunction with the fingerprint authentication
functionality, you can substitute fingerprint authentication for password entry when turning on your computer. For more information, see
Using
Fingerprint Authentication (page 114) .
