Title:
  cannot suspend, black screen - need to power off

Status in linux package in Ubuntu:
  New

Bug description:
  It seems a common bug ever since several years back, however no
  conclusive fix have been found. Here's my problem:

  First, I have an HP pavilion dv6 laptop. I recently installed Ubuntu
  16.04 alongside Windows 10 by partitioning my HD. Everything is
  working flawlessly except the 'suspend'/hibernate process - which
  needless to say is very important !

  The laptop will not sleep/suspend if I close my lid. More
  intriguingly, if I press 'suspend' manually, the screen goes all blank
  (black) and the fan starts to work alongside everything (wifi-button
  capslock... all as they were before pressing suspend) but I cannot do
  anything so stop it. My only option every single time is to use brute
  force and poower-off via the power-button and then on again.

  Please help me fix this and for several hundred others...
