I suspect that reusing the H8 EC code for the xx30 series Thinkpads is a source of bugs. There isn't any H8 EC on those mainboards anymore, the EC was replaced with a completely different SMSC MEC1619. The T440p port seems to have a few bugs which might be due to the different EC.
Is the EC on the xx20 series Thinkpads (e.g. X220) an H8 EC or not?
AFAIK, yes. The specific H8S model used varies, but they are similar. I re-checked the T440p and it uses a different SMSC MEC1633L EC. That would explain why only the T440p had some weird issues regarding EC stuff.
Best regards, Angel
