System Sequrity: Supervisor Password requierd

@shimekeleme the Supervisor Password (SVP) is stored in the non-volatile memory of the Embedded Controller (EC) of the system and is tied to the Trusted Platform Module (TPM). Your system is locked down at the hardware level in order to prevent wiping of the board. There are no backdoor codes, no master generator websites and no jumper to clear the password for modern ThinkPads.

The official Lenovo policy for a forgotten SVP on these computers is to replace the complete motherboard. You can alwasy try to clear the SVP by connecting a JTAG/SPI programmer to the EC pins on the motherboard, then you would need to read out the raw firmware and to patch the SVP block in the hex editor. then you need to reflash the firmware. Unless you own an EEPROM programmer and know how to read board schematics and can edit a firmware file, you are permanently locked out of this computer.

Firmware, software, flashing and missing (forgotten) passwords are really not what we deal with on here. We are more of the hardware repair kind of group. For your "issue" I suggest you check those forums that deal with that. you could check on here as well as on here for a start.
