Using Windows BitLocker Drive Encryption
To help protect your computer against unauthorized access, use the drive encryption software, such as
Windows BitLocker Drive Encryption.
Windows BitLocker Drive Encryption is an integral security feature of some editions of the Windows
operating system. It can help you protect the operating system and data stored on your computer, even
if your computer is lost or stolen. BitLocker works by encrypting all user and system files, including the
swap and hibernation files.
BitLocker uses a Trusted Platform Module to provide enhanced protection for your data and to ensure early
boot component integrity. A compatible TPM is defined as a V1.2 TPM.
To check the BitLocker status, go to Control Panel, and click System and Security ➙ BitLocker Drive
Encryption.
For more information about Windows BitLocker Drive Encryption, see the help information system of the
Windows operating system, or search for "Microsoft Windows BitLocker Drive Encryption Step-by-Step
Guide" on the Microsoft Web site.
Disk Encryption hard disk drive and Encryption solid-state drive
Some models contain the Disk Encryption hard disk drive or Encryption solid-state drive. This feature 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 device.
Using the fingerprint reader
Depending on the model, your computer might have a fingerprint reader. Fingerprint authentication can
replace your Windows password. In this way, you can log in to your computer simply and securely. To
enable fingerprint authentication, enroll your fingerprints first.
Enrolling your fingerprint
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:
• For Windows 7 and Windows 8.1
1. Start the Lenovo Fingerprint Manager program. For instructions on how to start the Lenovo
Fingerprint Manager program, see "Lenovo programs" on page 14.
2. Enter the Windows password as required.
3. Click the icon for the finger that you want to enroll, and constantly swipe your corresponding finger
across the fingerprint reader until the enrollment completes.
4. Click Finish. Your fingerprint is enrolled successfully.
For more information about how to use the fingerprint reader, refer to the help system of the Lenovo
Fingerprint Manager program.
• For Windows 10
1. Open the Start menu and then click Settings. If Settings is not displayed, click All apps to display all
programs, then click Settings ➙ Accounts ➙ Sign-in options.
