Bug description:
  I have an HP laptop in a docking station.
  It has been working fine for months, but now it crashes and I have to hold 
the power button to restart. Black screen.

  Example 1:
  The PC is docked, lid closed. I turn it on, login and the two external 
monitors go black.
  Restart PC but holding power button. (Undocking / Opening the lid does 
nothing)

  When the desktop is loaded, I close the lid. The two external monitors go 
black.
  PC goes black, does not respond.
