We have 2 X1 Yoga 2nd Gen laptops that had the same issue. Thunderbolt failure that led to a missing thunderbolt controller and no longer charging.
Before anyone suggests
Things we have done:
pressed the reset button
unplugged the cmos battery
changed the battery completely
Downloaded new drivers but Thunderbolt controller is missing and can't update. (they are both dead so and I can't remember exactly what is going wrong)
Can't update firmware since we can't keep it on a charger as it wont charge.
Currently don't have a Yoga X1 Gen 2 doner laptop except my coworkers so he is haven't to swap the batter in and out to give it power to do more testing when he can.
I am assuming this is a full board replacement as they didn't seperate the Powerboard from the Mainboard unlike what they did with the Power switch which is on a seperate board....seems odd to me. Any doner board would come from a thirdparty and isn't something we are willing to do at this time.
I would like to know if anyone else has had this problem as this is 2 out of the 8 we bought that are completely dead. Any help would be greatfully apprecitated.
