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.

drive. Refer to the procedures in “Power-on password” on page 47 and “Hard disk passwords” on page

• 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 52.
