New HP Elitebook 850 G6.
- Issue: black screen when booting with the HP Thunderbolt dock G2
- Raising the laptop lid doesn't fix the issue, both screens are black.
- Seems to occur (more frequently) since the latest docking station firmware upgrade.
- Relevant post: https://community.spiceworks.com/topic/2255741-thunderbolt-dock-230w-g2-outboard-monitor-problems
