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, hybrid drive, or solid-state
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, hybrid drive, or solid-state 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, hybrid drive, or solid-state drive. You must take your computer to a Lenovo reseller or a
marketing representative to have the hard disk drive, hybrid drive, or solid-state drive replaced. Proof of
purchase is required, and a fee will be charged for parts and service.
