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.
• 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
22
P620 User Guide
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.
Note: 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.
• System management password (for selected models)
You can enable the system management password to have the same authority as the supervisor
password to control security related features. To customize the authority of the system management
password through the UEFI BIOS menu:
1. Restart the computer. When the logo screen is displayed, press F1 or Fn+F1.
2. Select Security ➙ System Management Password Access Control.
3. Follow the on-screen instructions.
If you have set both the supervisor password and the system management password, the supervisor
password overrides the system management password.
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 Supervisor Password, Set Power-On Password, Set
System Management 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 should record your passwords and store them in a safe place. If you forget the passwords, see “Clear
CMOS” on page 31 to remove them by yourself. You can also contact a Lenovo-authorized service provider
to have the passwords removed.
Notes:
• If the supervisor password is forgotten, it might not be removed by clearing CMOS depending on your
BIOS settings.
• If the hard disk password is forgotten, Lenovo cannot remove the password or recover data from the
storage drive.

Use firewalls
A firewall can be hardware, software, or a combination of both depending on the level of security required.
Firewalls work on a set of rules to determine which inbound and outbound connections are authorized. If the
computer is preinstalled with a firewall program, it helps protect against computer Internet security threats,
unauthorized access, intrusions, and Internet attacks. It also protects your privacy. For more information
about how to use the firewall program, refer to the help system of your firewall program.
To use firewalls:
1. Go to Control Panel and view by large icons or small icons.
