HP Recommended
Product: Elitebook 8470p/8460p AMD vid
Operating System: Microsoft Windows 10 (64-bit)

this is an old unsolved topic

http://h30434.www3.hp.com/t5/Notebook-Video-Display-and-Touch/8460p-video-AMD-Win-8-0-x64-video-driv...

 

but now I know what's going on.

 

The problem always happens when the Elitebook has a secondary monitor connected either at the VGA or DisplayPort;

when the PC comes back from sleep erraticlly crashes forcing the OS re-start (W10/W8.1/W8/W7, etc).

 

The point is that when the PC is at sleep the signals between the secondary monitor and the PC erratically crash the PC.

If before I send the PC to sleep I turn the secondary monitor off and I keep it off until the PC is later back on (awake) then the crash never happens again.

 

The problem is surelly the driver that is not turning the second monitor lines off when sleeping. I have tried million drivers, and configurations; they all suffer of this problem.

 

 

Best,

Patrick
