If you forget the user hard disk password, or both user and master hard disk passwords, Lenovo cannot reset your passwords or recover data from the hard disk drive or hybrid drive. You must take your computer to a Lenovo reseller or a marketing representative to have the hard disk drive or hybrid drive replaced. Proof of purchase is required, and a fee will be charged for parts and service. Hard disk security To protect passwords from unauthorized security attacks, refer to the following tips to maximize security: • Set a power-on password as well as a hard disk password for your internal solid-state drive, hard disk drive or hybrid drive. Refer to the procedures in "Power-on password" on page 55 and "Hard disk passwords" on page 57. 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 60. Note: The Microsoft Windows 7 and Windows 8.1 operating system support the TPM management feature. • If a Disk Encryption hard disk drive, an Encryption solid-state drive, or a Disk Encryption hybrid drive 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 8.1 operating system. Refer to "Using Windows BitLocker Drive Encryption" on page 60. Chapter 4. Security 59
