Monitors stopped working

[Demonio_Azul]

Hi there...

I have an HP Zbook Fury 17 G7 laptop and an HP Thunderbolt Zbook 3 Dock.

I have two monitors connected to the laptop via the docking station, one is DisplayPort and the other is VGA. I have been working with these monitors for over 5 years now with no issues. Last Friday, at the end of the business day, I worked with them quite normally, there were no Windows updates, no reboots, no nothing. Today, Monday morning, the monitors show as not having an input signal. I did nothing different to cause this.

The monitors have no HDMI output, so I cannot try to connect them directly to the laptop, because my laptop has only one HDMI input.

I have consulted many of the entries in this community and updated all the drivers and Windows 10 is up to date as well. 

I have no idea what is wrong.  I have opened a ticket with my company's HelpDesk but they are quite slow to answer and I need the monitors. The problem is that I tried everything except the BIOS update which is locked by company policies... so I would expect to hear something else than "Please update the BIOS" because from Friday to Monday this shouldn't be happening... 

Thank you for any hints!

Cheers,

This has happened to me on both of my HP ProBooks.  I had to send them back to HP.  Fortunately, they were still under warranty.  However, it was the mainboard in my case.   

That being said, I did also notice that a powered dock made a difference.   Our company invested in all the same laptop, and it started happening to all our laptops about the same time.  I would not doubt it was something with a windows update, but no way to confirm that .

Thanks @NashuaDataSolut.... I am afraid I am expecting a hardware malfunction as well... I think there will be no other thing but to wait for my HelpDesk to see what they reply... my laptop is also under warranty, so I think I may even get a new one... but the problem is configuring it when you have all these people hurrying you to get a reply for all their issues and questions at work...
