I have the same laptop and am experiencing the same bug. I have tried upgrading to 4.8.0-30-generic but that does not fix the problem for me. I did try and turn off all monitors except the laptop monitor before undocking and that allowed me to put the laptop to sleep. I could not wake it up, though.
