I have the same problem with a Thinkpad x240. Never managed to figure it out, instead I just use suspend which works reliably.

  I normally just use suspend too. I would definitely suggest trying the 4.8 kernel as mentioned in another comment. So far I haven't been able to make it fail.

    By any chance, do you know which kernel commit(s) fixed your issue? Maybe git bisect can pinpoint the commit? It would be interesting to know what the exact bug was.
