Title:
  video not working after resume

Status in linux package in Ubuntu:
  Confirmed
Status in linux source package in Xenial:
  Confirmed

Bug description:
  I suspended my x250.  Then plugged it in (overnight).  Then unplugged
  it.  Then opened it.  It resumed, but video did not work.  I closed
  the lid and opened it, a few times.  No dice.  Then, I pressed the
  power button, and the video came back on.  I was sitting next to
  Leann, Chris, and Brad here at the CDO Sprint.
