Located immediately next to the Hirose board-to-board connectors are small MLCC (Multi-Layer Ceramic Capacitors) filtering the raw 5V input. Because these capacitors handle incoming power directly from the baseboard, voltage spikes frequently cause them to crack internally and fail closed, creating a direct short-to-ground (0 Ohms).
