Using passwords

supervisor password, no one can change the configuration of the tablet.

easier. It is recommended that you record your password and store 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.
