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 47. For security, a longer password is
recommended.
2. To provide reliable security for UEFI BIOS, use the security chip and a security program with a Trusted
Platform Module management feature. Refer to "Setting the security chip" on page 53.
Note: The Microsoft Windows 7 and Windows 8 operating system support 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
and Enterprise editions of the Windows 7 operating system and Windows 8 operating system. See
"Using Windows BitLocker Drive Encryption" on page 52.
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 57.
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 and and Windows 8
operating systems. It is supported in the Ultimate and Enterprise editions of the Windows 7 operating
system and Windows 8 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.
