3. Technical Background

Most Lenovo laptops from the mid-2000s to early 2010s store BIOS passwords in a serial EEPROM (e.g., 24Cxxx series) or within the EC (Embedded Controller) flash. Unlike desktop CMOS memory, these passwords persist after power loss and battery removal.

RCUnlocker exploits either:

  • Known master password algorithms (weak cryptographic hashing based on serial number + static key).
  • Direct communication with the EC via the smbios or port 0x80 interface.
  • Generation of backdoor passwords that Lenovo service centers historically used.

Note: The tool does not brute-force passwords; it calculates them deterministically.
