Because the KBC1126-NU does not have internal flash memory, replacing it is often easier than other KBC types (like the NPCE series) because it the controller itself after soldering.
A common fix for "no power" issues associated with a hot KBC is to reprogram or replace the main BIOS flash chip.
The IC handles states from complete shutdown (G3) to soft-off (S5) and active operational states (S0). It acts as the gatekeeper that listens for the power button press before asserting the necessary enable lines for primary voltage rails (+3VALW, +5VALW). kbc1126nu datasheet hot
