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 lenovo t470 bios password reset verified
Non-Volatile Storage: The supervisor password (SVP) is stored on a separate EEPROM chip on the motherboard. This chip retains data even without power, meaning power-cycling or CMOS battery removal will only reset the system clock and Power-On passwords, not the supervisor password.
Security Redesign: Lenovo updated the BIOS security starting with the *40 series (e.g., T440). Older "tricks" like shorting specific pins on the chip during boot-up often result in a bricked motherboard on T470 and newer models. Verified Reset Methods
For a T470 with a forgotten supervisor password, there are only two widely verified solutions: 1. Official Motherboard Replacement
Lenovo's official stance for a lost supervisor password is that the entire motherboard must be replaced.
Cost: This is typically the most expensive option but is the only "official" way to restore a unit under warranty.
Verification: This can be done through an authorized Lenovo Support center. 2. Advanced Hardware Reprogramming (DIY/Third-Party)
This method involves physically reading the BIOS chip's data, patching it to remove the password, and writing it back.
Required Tools: An SPI flash programmer (such as the CH341A), a SOIC8 clip to attach to the chip without soldering, and a second computer. Process: Dismantle the laptop to access the motherboard. Locate the BIOS/EEPROM chip.
Use the programmer to "dump" (copy) the current BIOS firmware to a file.
Use specialized tools or services (like those found on community forums like AllService) to patch out the password from the dump. Flash the new, "clean" firmware back onto the chip. Methods That Do Not Work
CMOS Battery Removal: Only resets the date/time and simple user passwords; it does not clear the supervisor password.
Master Passwords: Modern ThinkPads do not have "backdoor" or universal master passwords.
Emergency Reset Hole: The small hole on the bottom of the T470 is for a "hard reset" if the system freezes, similar to pulling the battery. It does not affect security settings.

There’s nothing worse than powering on your T470 only to be met with a locked BIOS screen. Whether it’s a forgotten supervisor password or a second-hand laptop with an unknown credential, you have options.
After testing multiple methods, here is the verified, working procedure that does not require shorting EEPROM pins or expensive tools. A small paperclip or thin tweezers Steady hands
Before opening your laptop, try this: Remove the SSD and all RAM sticks. Sometimes the T470 locks the BIOS based on hardware hashing. Power on without RAM. If it prompts for a password, this won't help. But on 1% of units, removing the storage forces a default state. (It’s free, so try it.)
