I'm experiencing sleep/resume issue with my Lenovo two
laptops, same problem my friend sees, only he did file a
support request to Lenovo.
Wasn't it discussed right on this list a few days ago, on a separate thread also started by you?
It seems to me the issue is still being worked on.
It doesn't seem to be specific to Lenovo or Fedora either, but a result of the "standards" pushed by Microsoft for Win10 which deprecate older standards... ("Modern Standby")
