However, this policy is mainly to prevent unauthorized access. For those who legitimately own their device and have lost the password, third-party community-developed tools and advanced procedures offer viable solutions.
Disassemble the laptop casing to locate the physical SPI Flash EEPROM chip on the motherboard. Connect the programmer clip to the chip pins. Dump the current BIOS hex dump using a secondary computer.
