Surface Book not coming out of sleep


My SurfaceBook now will not wake from sleep properly – after last Tuesday’s cumulative updates.


  • Plugged into SurfaceDock
  • Walk away for a few minutes…press a key to wake it up
  • All I get is a black screen (on both) and my mouse pointer flashing but moveable
  • The only way to recover from this is to disconnect from dock and then reconnect
  • Then I waste time putting everything back the way I had it on the second monitor

Any clues as to resolve this issue? I’ve already run the Surface Dock update utility which says it is up to date.
