KBEC embedded controller firmware for the Lenovo ThinkPad T14 Gen 2, associated with an ITE controller referenced as 567901 in the name. No board number is given, so confirm the machine and EC chip before use. The EC controls power-on, battery charging, the keyboard, and thermal management. Reflashing it can revive a board that will not power on even though the main BIOS is intact. Back up the existing contents with a programmer before writing, and check the image size against the target chip.
