cannot suspend, black screen - need to power off

[edmond]

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...
