Hard disk password

There are two kinds of hard disk passwords:
• User hard disk password - for the user
• Master hard disk password - for the system administrator, who can use it to get access to the hard disk
even if the user has changed the user hard disk password
Note: There are two modes for the hard disk password: User only and Master + User. The Master + User
mode requires two hard disk passwords; the system administrator enters both in the same operation. The
system administrator then provides the user hard disk password to the system user.
Attention: If the user hard disk password has been forgotten, check whether a master hard disk password
has been set. If it has, it can be used for access to the hard disk drive. If no master hard disk password is
available, neither Lenovo nor Lenovo authorized service technicians provide any services to reset either
the user or the master hard disk password, or to recover data from the hard disk drive. The only Lenovo
and Lenovo authorized servicer solution to put the system back to operational status would be to replace
the drive for a scheduled fee.
To remove a user hard disk password that has been forgotten, when the supervisor password and master
hard disk password are known, do the following:
1. Insert the tablet into the keyboard dock and turn on the tablet.
2. When the logo screen is displayed, immediately press F1.
3. When the user hard disk password icon is displayed on the screen, press F1. The master hard disk
password icon is displayed.
4. Enter the master hard disk password to enter the ThinkPad Setup program.
5. Select Security.

New Password field blank, and press Enter twice.
