Today will be one more time HP Specialist to replaced another systemboard. When I talk with him by a phone he said that problem is escalated and he kindly ask to do not make bios updates for now. All my warranty tickets are opened and escalated.
If I didn'r receive and information for a week I will make updates bios and one more time make phone call to HP Specialist to replace another boards lol
As I said before I'm so angry for this situation that I will regulary will have replacing board. God bless that I have hp onsite carpack.
