Lenovo T470 Bios Password Reset Verified ((hot))

The phrase "verified" in the context of BIOS password resets usually refers to a specific procedure involving the hardware maintenance manual, the removal of the CMOS battery, or shorting specific jumpers on the motherboard.

• No CMOS battery trick: Removing the main battery, CMOS battery, and holding the power button for 60 seconds does nothing. The T470 stores passwords in non-volatile memory within the Embedded Controller (EC).
• No backdoor passwords: Lenovo abandoned master passwords after the Core 2 Duo era. Websites claiming to generate a master password for a T470 based on a “date code” are fraudulent.
• SPI Flash is the key: The password lives in the MEC1653 EC or the BIOS SPI flash chip. Resetting it requires direct hardware communication.

Step 2: Connect the CH341A

• The Lenovo ThinkPad T470 is a solid business laptop; resetting a BIOS (Supervisor) password on it is possible but nontrivial, varies by method, and carries risks (data loss, warranty/TPM complications, and legal/ethical concerns).
