Thank you for contacting us, I was reading your thread and I know that you are having a thunderbolt issue, I will be more than glad to assist you.
I have read this thread and I have noticed this issue seems to be related to the thunderbolt drivers provided by HP. Please bear in mind the thunderbolt drivers available on our Intel web site were developed for Intel® NUC only. My suggestion would be contacting HP and check for future drivers or check if they have any information about this matter.
