Tips on using the hard disk passwords
• You can set the minimum length of a hard disk password through the Security menu.
• If you set a hard disk password of over seven characters, the hard disk drive can be used only with a
computer that can recognize a hard disk password of over seven characters. If you then install the
hard disk drive in a computer that cannot recognize a hard disk password that contains more than
seven characters, you cannot access the drive.
• Record your password and store it in a safe place. 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. You must take your computer to a Lenovo reseller or a marketing representative to have the hard
disk 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 or hard disk
drive. Refer to the procedures in “Power-on password” on page 51 and “Hard disk passwords” on page
53. For security, a longer password is recommended.
• To provide reliable security for the 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 56.
• If a Disk Encryption hard disk drive and Encryption solid-state drive is installed in your computer, be sure
to protect the contents of your computer memory from unauthorized accesses 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, Windows 8, and Windows 8.1 operating system. See “Using
Windows BitLocker Drive Encryption” on page 56.
