Supervisor Password; How To Remove The Hard-Disk Password - Lenovo Ideapad Z560 Hardware Maintenance Manual

Supervisor password

A supervisor password (SVP) protects the system information stored in the
BIOS Setup Utility. The user must enter the SVP in order to get access to the
BIOS Setup Utility and change the system configuration.
Attention: If the SVP has been forgotten and cannot be made available to
the servicer, there is no service procedure to reset the password. The system
board must be replaced for a scheduled fee.

How to remove the hard-disk password

Attention: If User only mode is selected and the user HDP has been forgotten
and cannot be made available to the servicer, neither Lenovo nor Lenovo
authorized servicers provide any services to reset the user HDPs or to recover
data from the hard disk drive. The hard disk drive can be replaced for a
scheduled fee.
To remove a user HDP that has been forgotten, when the SVP and the master
HDP are known, follow the steps below:
1. Turn on the computer; while the initial screen is displayed, press F2; then
the BIOS Setup Utility screen opens.
2. Select Security, using the cursor directional keys to move down the menu.
3. Select Password.
4. Select Hard-disk x password, where x is the letter of the hard disk drive. A
pop-up window opens.
5. Select Master HDP.
6. Type the current master HDP in the Enter Current Password field. Then
leave the Enter New Password field blank, and press Enter twice.
7. Press F10.
8. Select Yes in the Setup Configuration window. Both user HDP and master
HDP will have been removed.
