For sure some bits are missing. This laptop doesn't have an EC per-se, it's got a "EMEC" - Emulated EC, where on Windows there's just a bunch of drivers handling EC-like functionality. So e.g. already for battery, we just talk with the sbs-battery directly. I assume this will be the case for the other components on this laptop as well. Regards Luca
