Disk Encryption hard disk drive and Encryption solid-state drive
Some models contain the Disk Encryption hard disk drive, Encryption solid-state drive, or Encryption hybrid
drive. This encryption technology helps to protect your computer against security attacks on media, NAND
flash, or device controllers by use of a hardware encryption chip. For the efficient use of the encryption
feature, set a hard disk password for the internal storage drive.
Setting the security chip
Strict security requirements are imposed on network client computers that transfer confidential information
electronically. Depending on the options you ordered, your computer might have an embedded security chip
(a cryptographic microprocessor). With the security chip, you can do the following:
• Protect your data and system
• Strengthen access controls
• Secure communications
Before you start, print these instructions.
To set an item on the Security Chip submenu, do the following:
1. Restart the computer. When the logo screen is displayed, press F1 to start the ThinkPad Setup program.
2. Select Security
➙
Security Chip by using the directional keys.
3. Press Enter. The Security Chip submenu opens.
4. Move to an item you want to set by using the directional keys. When the item is highlighted, press Enter.
5. Set other items that you want to set.
6. Press F10. A Setup Confirmation window is displayed. Select Yes to save the configuration changes and
exit.
Notes:
• Ensure that the supervisor password has been set in ThinkPad Setup. Otherwise anyone can change the
settings for the security chip.
• When you clear the security chip, turn off your computer and then turn it on again after you set the security
chip to Active . Otherwise, the Clear Security Chip option is not displayed.
Using the fingerprint reader
Depending on the model, your computer might have a fingerprint reader. Fingerprint authentication can
replace your passwords, such as the Windows password. In this way, you can log in to your computer simply
and securely.
Enrolling your fingerprints
To enable fingerprint authentication, enroll your fingerprints first. 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.
To enroll your fingerprints, do the following:
1. Open the Start menu and then click Settings ➙ Accounts ➙ Sign-in options .
2. Follow the instructions on the screen to finish the enrollment.
