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:
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 “Using passwords” on page 49. 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 55.
Note: The Microsoft Windows 7 operating system supports the TPM management feature.
3. 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. See “Using Windows BitLocker Drive
Encryption” on page 54
.
4. Before you dispose of, sell, or hand over your computer, be sure to delete data stored on it. See “Notice
on deleting data from your hard disk drive or solid state drive” on page 59
.
Notes: The following drives can be protected by UEFI BIOS:
The hard disk drive built into your computer.
The hard disk drive installed in a Serial Ultrabay Slim bay.
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 Windows 7. It is supported in the
Ultimate and Enterprise editions of the Windows 7 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 les, including the swap and hibernation les.
BitLocker uses a Trusted Platform Module to provide enhanced protection for your data and to ensure early
boot component integrity. A compatible TPM is dened as a V1.2 TPM.
