A:AnswerI am not certain if it will. I know for the new generation X1 carbons Lenovo changed the input side of the adapter ( The side that plugs into the computer). I am not sure if lenovo changed it across all laptops. You can search online or Lenovo directly to confirm. I do know it works for the t460 bc I had it. Hope this helps.
