You can set passwords in UEFI (Unified Extensible Firmware Interface) BIOS (Basic Input/Output System) to strengthen the security of your computer.
Power-on password
When a power-on password is set, you are prompted to enter a valid password each time the computer is turned on.
Supervisor password
Setting a supervisor password deters unauthorized users from changing configuration settings. If you are responsible for maintaining the configuration settings of several computers, you might want to set a supervisor password.
When a supervisor password is set, you are prompted to enter a valid password each time you try to enter the BIOS menu.
If both the power-on password and supervisor password are set, you can enter either password. However, you must use your supervisor password to change any configuration settings.
Hard disk password
After you set a hard disk password, your data on the storage drive is protected even if the storage drive is removed from one computer and installed in another.
Before you start, print these instructions.
Restart the computer. When the logo screen is displayed, press F1 or Fn+F1.
Select Security.
Depending on the password type, select Set Supervisor Password, Set Power-On Password, or Hard Disk Password and press Enter.
Follow the on-screen instructions to set, change, or remove a password.
Press F10 or Fn+F10 to save the changes and exit.
If the hard disk password is forgotten, Lenovo cannot remove the password or recover data from the storage drive.
