 shows updates for the thunderbolt firmware, but they are older than this computer. Is there a newer version for zbook 15 g6. Trying these updates doesn't complete properly

thanks for your inputs

Your dock is the 1st gen TB dock... I would update the Zbook while the dock is unplugged with HP Image Assistant... Make sure that all is updated, including the BIOS AND all drivers, and Intel components... then, plug in the dock and run HP Image Assistant again to see if it finds additional dock related updates to do

then, run the dock f/w updater

Thanks for the suggestion. Unfortunately, the same problem occurs after doing the updates as suggested.
