Toughbooks are great machines and well developed to hava a looooong life. There are plenty Company specific Toughbooks who are sold daily for a second life out there. No reason to give it to the garbage because it was manufactured for a specific company. Also the companies get good money when they sell it after a short lease from lets say 2 to 5 years and should take care the machine is free from EVERY custom specific SOFTWARE and PASSWORDS.
My issue:
I was on the search for a relative new Toughbook and bought a CF53 mk2 (CF53JGW69FG). As i found out it seems there is a customer specific supervisor password installed which is activated when loading the bios setup defaults.
The TB comes without bios password. What i did is set a supervisor password since its neccessary to activate TPM. After tests went good i wanted to clean up totally to make the w7 TB a w10 TB.
I started with save the bios function (wherever the TB saved it ???) and loading the setup defaults in the bios.
AND from that point on i cannot access the bios anymore. The supervisor password i gave the TB is not working or lets say overruled by the custom settings in the setup defaults.
I called panasonic toughbook service and had a friendly chit chat to get the following information:
The TB is customer specific model and there are two ways to access the bios again.
1.) Get the password from the Company, sure they are not allowed to tell me for which company the machine was produced for
2.) Get the machine to panasonic to change the mobo. Since i was not interested i did not ask for costs or if the machine will arrive back to me with the customer specific setup defaults (the unknown supervisor password) or they will set it free
My 53 mk2 is still in warranty

Is there somebody out who run in this problem and have a recommended method to get this TB run with ownership TPM ???
