Resetting a BIOS supervisor password on a Lenovo ThinkPad T470 is significantly more difficult than on older laptops. Because the password is stored in non-volatile memory (EEPROM), traditional methods like removing the CMOS battery are no longer effective for this specific model. Core Challenges with T470 BIOS Security
Restricts access to the BIOS/UEFI settings. This is the primary hurdle for hardware modifications. The Storage Mechanism lenovo t470 bios password reset verified

Locks the storage drive itself. If this is lost, the data is usually unrecoverable. Method 1: The "Backdoor" Key (Official Route)
