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 storage drive. Refer to the
procedures in “Power-on password” on page 53 and “Hard disk passwords” on page 55. For security,
a longer password is recommended.
• 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 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 58.
• Before you dispose of, sell, or hand over your computer, delete the data stored on it. For more information,
refer to “Notice on deleting data from your storage drive” on page 60.
The hard disk drive built into your computer can be protected by UEFI BIOS.
