When official support is unavailable—perhaps due to a second-hand purchase without a receipt or a defunct company—the user enters the gray area of hardware-level intervention. For the ThinkCentre M720q, this is not for the faint of heart. It often involves shorting specific pins on the BIOS chip itself, a procedure known as an SPI (Serial Peripheral Interface) flash attack. An advanced user would need to disassemble the tiny chassis, locate the 8-pin BIOS flash memory chip, and use an external programmer (like a CH341A) connected via test clips to read, modify, or re-flash the firmware. Alternatively, some have discovered specific pin bridges on the motherboard that, when shorted during a precise moment in the boot process, can bypass the password check. These methods require a steady hand, detailed schematics, and a willingness to accept the risk of permanently bricking the motherboard.

Official Support: If the jumper method fails, Lenovo's official policy for lost Supervisor passwords usually requires a system board replacement.

If you're not comfortable with trying the above methods or if they don't work for you, you can contact Lenovo support for assistance. They may be able to provide you with a BIOS password reset procedure or offer additional guidance.
