Hard disk security

To protect passwords from unauthorized security attacks, several of the latest technologies and algorithms
are integrated into UEFI BIOS and hardware design of ThinkPad notebook computers.

To maximize security, do the following:

• Set a power-on password as well as a hard disk password for your internal solid-state drive or hard disk

drive. Refer to the procedures in “Power-on password” on page 40 and “Hard disk passwords” on page
40. For security, a longer password is recommended.

• To provide reliable security for UEFI BIOS, use the security chip and a security application with a Trusted

Platform Module (TPM) management feature. Refer to “Setting the security chip” on page 45.

Note:

The Microsoft Windows 7 and Windows 8 operating system supports the TPM management feature.

• If a hard disk drive or solid-state drive with encryption technology is installed in your computer, be sure

to protect the contents of your computer memory from unauthorized access by use of drive encryption
software, such as Microsoft Windows BitLocker

Drive Encryption, which is supported in the Ultimate and

Enterprise editions of the Windows 7 operating system and Professional and Enterprise editions of the
Windows 8 operating system. See “Using Windows BitLocker Drive Encryption” on page 44.

• Before you dispose of, sell, or hand over your computer, be sure to delete data stored on it. Refer to

“Notice on deleting data from your hard disk drive or solid-state drive” on page 48.

Note:

The hard disk drive built into your computer can be protected by UEFI BIOS.

Using Windows BitLocker Drive Encryption

To help protect your computer against unauthorized access, be sure to use drive encryption software, such
as Windows BitLocker Drive Encryption.

Windows BitLocker Drive Encryption is an integral security feature of the Windows 7 and Windows 8
operating systems. It is supported in the Ultimate and Enterprise editions of the Windows 7 and Professional
and Enterprise editions of the Windows 8 operating system.

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
