Log in to your computer securely

This section provides secure ways to log in to your computer with a password or your face.

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 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 21 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 software security solutions

This section provides software solutions to secure your computer and information.

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,

M75q Gen 2 User Guide

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.

2. Click Windows Defender Firewall, and then follow the on-screen instructions.

Use computrace Agent software embedded in firmware (for selected models)

The Computrace Agent software is an IT asset management and computer theft recovery solution. The software detects if changes have been made on the computer, such as hardware, software, or the computer call-in location. You might have to purchase a subscription to activate the Computrace Agent software.

Use BIOS security solutions

This section provides BIOS solutions to secure your computer and information.

Erase all storage drive data

2. Restart the computer. When the logo screen is displayed, press F1 or Fn+F1.

3. Select Security ➙ Hard Disk Password ➙ Security Erase HDD Data and press Enter.

4. Select the storage drive you will recycle and press Enter.

Note: During the erasing process, the power button and the keyboard are disabled.

6. After the erasing process is completed, a message is displayed, prompting you to reset the system. Select Continue.

Note: Depending on the storage drive capacity, the erasing process will take half an hour to three hours.

7. After the resetting process is completed, one of the following will happen:

• If the data on the system storage drive is erased, you will be prompted that no operating system is

available.

• If the data on the non-system storage drive is erased, the computer restarts automatically.

To bypass the error message and log in to the operating system:

1. Properly install or close the computer cover.

2. Enter the BIOS menu, save and then exit.
