Hard disk security

Your computer supports an enhanced security solution for solid state drive or hard disk drive. To protect passwords from unauthorized security attacks, several of the latest technologies and algorithms are integrated into UEFI BIOS and hardware design of ThinkPad notebooks.

To maximize security, do the following:

1.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 90 and “Hard disk passwords” on page 91. For security, a longer password is recommended.

2.To provide reliable security for UEFI BIOS, use the security chip and a security application with a Trusted Platform Module management feature. Refer to “Setting the security chip” on page 96.

Note: Microsoft Windows 7 and Windows Vista support TPM management feature.

3.If a “Disk Encryption hard disk drive and Encryption solid state drive” on page 96 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 in Windows 7 and Windows Vista. Refer to “Using Windows BitLocker Drive Encryption” on page 95.

4.Before you dispose of, sell, or hand over your computer, make sure to delete data stored on it. Refer to “Notice on deleting data from your hard disk drive or solid state drive” on page 105.

Notes: The following drive(s) can be protected by UEFI BIOS:

• The hard disk drive built into your computer.

Using Windows BitLocker Drive Encryption

To help protect your computer from being subject to 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 Windows 7 and Windows Vista. It is supported in Ultimate and Enterprise editions of Windows 7 and Windows Vista. It can help you protect the operating system and data stored in your computer data, 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, do the following:

•For Windows 7: Click Start ➙ Control Panel ➙ System and Security ➙ BitLocker Drive Encryption.

•For Windows Vista: Click Start ➙ Control Panel ➙ Security ➙ BitLocker Drive Encryption.
