New HP Elitebook 850 G6.

  • Issue: black screen when booting with the HP Thunderbolt dock G2
  • Disable Win 10 "Turn on fast startup (recommended)". Can be done via Control Panel or registry ([HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Power] "HiberbootEnabled"=dword:00000000)
  • Update HP Thunderbolt Dock G2 firmware -> already done (through assistant).
  • Update BIOS -> boot in BIOS, select update BIOS. Current BIOS was 1.5.03 (or something), upgraded to 1.6.
  • ... problem seems to be fixed now.
  • Let's re-enable the fast startup (maybe was still using an old G2 driver).
  • ... Still having some issues. Unplug/Plug the docking seems to fix the issue, but I don't want to do that. Possible alternative fixes:
  • Keep "HiberbootEnabled"=dword:00000000
  • Checked FW again, and in fact the docking FW upgrade did fail. Try to reinstall...
  • Try with an HDCP monitor, or better yet an HP HDCP monitor.
