Product: HP EliteBook x360 1040 G5 Notebook PC
Operating System: Microsoft Windows 10 (64-bit)

I've been running my laptop HP Elitebook X360 through my HP USB-C Dock G5  with 3 external monitors connected for a year now, but today the  external monitors stopped being detected while HP was installing an update. All screens turned black (no signal output). After installation they still didn't work. I have tried restarting, unplugging and restarting everything again. Uninstalling and then reinstalling the latest updates, but nothing helps. 
I don't know what to do next? Any ideas / suggestions I can try?

I dont know what update was installed so I cant really say, but I would try reverting Windows back via a Restore Point prior to when this update was first installed. Usually it works, not sure if the update actually altered the HP Dock though.

Hope it helps.

Thanks for your advise! I have been in contact with HP helpdesk and they have solved the problem. Apparently the problem was caused by a bios update which wasn't performed correctly. So, I updated the bios again and now all external monitors are working again.

A bios update failed? You got lucky sounds like. If it really went south, it would have bricked your laptop.

Glad its working now.

 

PS: Maybe you might want to consider creating Image backups to an external drive in case something does fail again?

Aomei or Macrium are a couple of popular programs that are free for that.

 

 

Good luck.

Yes, I know. I have an external drive where I save all my images as back up. But, thanks for the advise!
