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. The
hard disk drive can be replaced for a scheduled fee.

1. Turn on the computer.
2. When the ThinkPad logo is displayed, immediately press F1 to enter the ThinkPad Setup program.
3. Select Security.
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, where HDP stands for hard disk password.
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 Fn+F10 to save changes and exit the ThinkPad Setup program. The user hard disk password and
the master hard disk password have been removed.
