Product: EliteBook 840 G4 and G5, UltraSlim Dock
Operating System: Microsoft Windows 10 (64-bit)

Hello,

 

Hopeing someone has some advice.

 

We've been switching to HP laptops recently for faculty, with a docking station connecting to two external DP monitors.

 

A number of people have complained that when first docking the monitors continually flicker on/off.  Usually turning the laptop off, then back on resolves the immediate issue but obviosuly that is inconveneint.

 

We've seen this on Elitebook 840 G4 and G5 laptops.

 

Steps already taken on a G4 system to attempt resolve:

 

- Install latest Intel driver from HP Support site for laptop

- Install latest BIOS update from HP Support site

- Update firmware on dock to 2.33 (advised on other posts).

 

The problem however remains and is realiably reproducable. If the laptop is un-docked / re-docked the flickering display occurs.

 

Any suggestions on where to look next? All systems are still under warranty.

 

Many thanks,

 

Chris
