Use passwords
Password types
You can set the following passwords in UEFI (Unified Extensible Firmware Interface) BIOS (Basic Input/
Output System) 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. The computer cannot be used until the valid password is entered.
• Administrator password
Setting an administrator 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 an
administrator password.
When an administrator 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 administrator password are set, you can enter either password.
However, you must use your administrator 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.
Notes:
– 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.
– If the hard disk password is forgotten, there is no way to reset the password or recover data from the
storage drive.
Set, change, and remove a password
Before you start, print these instructions.
1. Restart the computer. When the logo screen is displayed, press F1 or Fn+F1.
2. Select Security .
3. Depending on the password type, select Set Power-On Password , Set Administrator Password , or
Hard Disk Password and press Enter.
4. Follow the on-screen instructions to set, change, or remove a password.
5. Press F10 or Fn+F10 to save the changes and exit.
You might want to record your password and store it in a safe place. Otherwise, if you forget the password,
you have to take your computer to a Lenovo reseller or a marketing representative to have the password
canceled. However, if you forget the hard disk password, Lenovo cannot reset your passwords or recover
data from the storage drive.
Use the fingerprint reader (for selected models)
If you use a mouse with a fingerprint reader on it, fingerprint authentication can replace your passwords and
enables you to log in to your computer simply and securely.
