Supervisor password

The supervisor password protects the system information stored in the ThinkPad Setup program. Without it,
no one can change the configuration of the tablet.
If you have set a supervisor password in the ThinkPad Setup program, you are prompt to enter a supervisor
password when you start the ThinkPad Setup program.
Note: The system administrator can set the same supervisor password on many tablets to make
administration easier.
Only a system administrator can set, change, or remove a supervisor password.
To remove the supervisor password, do the following:
1. Print these instructions.
2. Save all open files, and exit all applications.
3. Turn off the tablet.
4. Insert the tablet into the keyboard dock and turn on the tablet.
5. When the logo screen is displayed, immediately press F1. Type the supervisor password to enter
the ThinkPad Setup program.

Attention: You might want to take a note of your password and keep it in a safe place. If you forget
your supervisor password, Lenovo cannot reset your password. You must take your tablet to a Lenovo
reseller or a Lenovo marketing representative to have the system board replaced. Proof of purchase is
required, and a fee will be charged for parts and service.
