Solid state drive 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. Refer to
the procedures in Power-on password on page 46 and Hard disk passwords on page 46. 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 50.
3. If a solid state drive equipped with Encryption features 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. Refer to Using Windows BitLocker Drive
Encryption on page 50.
4. 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 solid state drive on page 55.
Note:
The solid state 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 Windows 7. It is supported in the
Ultimate and Enterprise editions of the Windows 7 operating systems. 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.
