2. Select Security ➙ Electronic Lock to enable or disable the E-lock.
3. Press F10 or Fn+F10 to save the changes and exit. Your computer will restart automatically and then

UEFI BIOS passwords
You can set passwords in UEFI (Unified Extensible Firmware Interface) BIOS (Basic Input/Output System) to
strengthen the security of your computer.
Password types
You can set a power-on password, supervisor password, system management password, or hard disk
password in UEFI BIOS to prevent unauthorized access to your computer. However, you are not prompted to
enter any UEFI BIOS password when your computer resumes from sleep mode.
• 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
Setting a hard disk password prevents unauthorized access to the data on the storage drive. When a hard
disk password is set, you are prompted to enter a valid password each time you try to access the storage
drive.
