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.
  • DONE - Keep "HiberbootEnabled"=dword:00000000
  • DONE - Checked FW again, and in fact the docking FW upgrade did fail. Try to reinstall... installed manually, now the installer reports that all components are up-to-date.
  • DONE - Say that Fast Boot must be disabled in BIOS for pre-boot usage. Not sure if this is necessary, or what are the consequences...
  • ... No more issues reported after several days...
  • More possible alternative fixes:
  • Try with an HDCP monitor, or better yet an HP HDCP monitor.
  • See Dock troubleshooting guide.
