Use the color sensor (for selected models)
The color sensor enables you to measure and adjust the color accuracy of your computer display. Therefore,
a color image or graphic is rendered as close as possible to its original intent. The color profile for your
computer display is preinstalled on your computer. If you want to install a different color profile, go to:
https://pcsupport.lenovo.com
To use the color sensor, open the Start menu, click X-Rite ➙ PANTONE Color Calibrator, and then follow
the on-screen instructions.
When the color sensor is in use, the color-sensor indicator on the computer outer lid blinks twice at regular
intervals. When the color measuring and adjustment finishes, the color-sensor indicator stays on.
After you use the color sensor for the first time, a calibration profile ECCM2SensorData.dat is generated. Back
up this calibration profile on an external storage device in case that both the color sensor and the internal
storage device are replaced.
To locate the DAT file, go to This PC ➙ Documents ➙ X-Rite.
The display provides a color profile that can work with the Microsoft Image Color Management (ICM)
function. If the graphics software you are using is compatible with ICM, you can display a color image on
your monitor and match it with the same quality one on another device, such as a scanner or a printer.
For more information about the Microsoft ICM, see the Windows help information.
Purchase accessories
Lenovo has a number of hardware accessories and upgrades to help expand the capabilities of your

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
© Copyright Lenovo 2019 21
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 the fingerprint reader
If the keyboard shipped with your computer has a fingerprint reader, you can log in to your computer simply
and securely by fingerprint authentication instead of passwords.
Enroll your fingerprints
Open the Start menu and then click Settings ➙ Accounts ➙ Sign-in options. Then, follow the on-screen
instructions to finish the enrollment.
During the enrollment, the fingerprints are associated with the Windows password automatically. It is
recommended that you enroll more than one fingerprint in case of any injuries to your fingers.

Log in with your fingerprint
If the fingerprint reader indicator blinks in amber, the authentication is not successful.
Maintain the fingerprint reader
To ensure that the fingerprint reader works correctly, do not:
• Scratch the surface of the reader with anything hard.
• Use or touch the reader with a wet, dirty, wrinkled, or injured finger.
Attention: If you always use your fingerprint to log in to the computer, you might forget your passwords.
Write down your passwords, and keep them in a safe place.
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,
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 antivirus programs
The computer is preinstalled with an antivirus program to help you guard against, detect, and eliminate
viruses.
Lenovo provides a full version of antivirus software on the computer with a free 30-day subscription. After 30
days, you must renew the license to continue receiving the antivirus software updates.
Note: Virus definition files must be kept up-to-date to guard against new viruses.
For more information about how to use your antivirus software, refer to the help system of your antivirus
software.

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
It is recommended that you erase all storage drive data before recycling a storage drive or the computer.
To erase all storage drive data:
1. Set a hard disk password for the storage drive you will recycle. See “Use passwords” on page 21.
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.

erasing process begins.
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.
Use the cover presence switch
The cover presence switch prevents the computer from logging in to the operating system when the
computer cover is not properly installed or closed.
