Seeing the same error on a 840 G10 laptop windows 10 22h2

Called HP.  They said I'd have to replace the motherboard.  Waiting on it to be shipped.  Seems like there should be a better solution because all the ports on the motherboard work fine.

Just had the same error on my Presidents notebook 840 G10, first time I've seen it.  We've had 80+ notebooks update the firmware in the last week and so far that was the only error BUT We've had some issues were the usb-c ports stop working, wont charge after this firmware update.  If we hard reset then they will work. But I am seeing in other forums that HP tells the users to replace the motherboard. 

I found this from a Dell customer back in 2022.  Did you have anything plugged into the usb-c ports besides power adapter while doing the install?

"I had the same issue with just the TbT Retimer 2 in a Dell XPS.  Each Thunderbolt (USB-C) port has a Retimer to boost signals.  If anything other than a power adapter is plugged in to one of these ports, it prevents the updating of the Retimer firmware.  A docking station will also prevent the updating.  I had an external screen plugged in which also delivered power, so I removed it and used a power adapter, then I had no more problems."

Thanks.  Gives same error with nothing plugged in.
