Trying to figure out how my #ThinkPad Edge #E531 does the detection that it has a "genuine" battery.

Of course it has to be implemented inside the EC firmware.

It is an ENE KB9012. I have the datasheet as well as a dump of its firmware and the schematics for the laptop. But I cannot find where it writes to or reads from the right #SMBus registers.

Does anyone know where I can get in contact with the right people in this domain?

@DerFetzer I'd recommend looking at an old UEFI/BIOS update image. It should have a few clues.
