„ Using passwords
Using passwords helps prevent your computer from being used by others.
Once you set a password and enable it, a prompt appears on the screen each
time you power on the computer. Enter your password at the prompt. The
computer cannot be used unless you enter the correct password.
For details about how to set the password, see the Help to the right of the
screen in the BIOS setup utility.
