Administrator Password
Setting an Administrator Password deters unauthorized persons from changing configuration settings. You
might want to set an Administrator Password if you are responsible for maintaining the settings of several
computers.
After you set an Administrator Password, a password prompt is displayed every time you access the Lenovo
BIOS Setup Utility program.
If both the Administrator and Power-On Password are set, you can type either password. However, you must
use your Administrator Password to change any configuration settings.
