How to remove the hard-disk password

Attention: If User only mode is selected and the user hard disk password has been forgotten and cannot be
made available to the service technician, neither Lenovo nor Lenovo authorized service technicians provide
any services to reset the user hard disk password, or to recover data from the hard disk drive. To put the
system back to operational status, the only Lenovo and Lenovo-authorized service solution would be to
replace the hard disk drive or solid-state drive with a scheduled fee.
To remove a user hard disk password that has been forgotten, when the supervisor password and the master
hard disk password are known, do the following:
1. Turn on the computer.
2. When the ThinkPad logo comes up, immediately press F1 to enter ThinkPad Setup.
3. Select Security, using the cursor keys to move down the menu.
4. Select Password.
5. Select Hard-disk x password, where x is the letter of the hard disk drive. A pop-up window opens.
6. Select Master HDP.
7. Type the current master hard disk password in the Enter Current Password field. then leave the Enter
New Password field blank, and press Enter twice.
8. Press F10.
9. Select Yes in the Setup confirmation window. Both user hard disk password and master hard disk
password will have been removed.
