hello. I have a dead Thinkpad MB. in looking up the serial, I get a very general result: X1 Yoga 2nd Gen (Type 20JD, 20JE, 20JF, 20JG) Laptop (ThinkPad) - Type 20JD. does this mean the same MB will fit all these models, or do I have to tear the unit down to find the serial on the MB to ensure fitment?
THANKS!!
THANKS!!
