HP Recommended
Product: HP Elitebook 840 G3
Operating System: Microsoft Windows 7 (64-bit)

Hello,

 

Running laptops with Win 7 x64 Enterprise as the OS and we've noticed after a recent purchase of 840 G3's that the monitors will blink and go to sleep without reasoning while docked. The laptops are still running in the background and still accept keystrokes / mouse inputs. We can remote them with RDP and other software, but the screen(s) themselves remain asleep. This has been causing major issues and after some searching on the HP site, we found a couple solutions. These have only assisted in eliminating the issue about 30% of the time.  This has occurred using VGA, DP, and conversion in between (USB->VGA / DP)


_Win 7x64 Ent SP1

_8-16GB RAM

_i5-6200U 2.3GHz

 

I have updated to the most recent BIOS

I have updated to the most recent video driver(s)

I have updated the firmware on the docks to the latest and greatest (has exacerbated the issue a couple times - no display at all)

 

Any information would be appreciated and I'll be opening a case with HP soon.

 

Thank you,

 

N
