Just for the record if someone else has this issue make sure that you reinstall the drivers BEFORE you do the vbios update (and make sure Nvidia GPU shows in device manager), otherwise the the vbios update will run, do nothing, and you will think you have done it. Also I installed the vbios update in safe mode. Not sure if that makes a difference but good to know...
RTX 2060 disappears.Unplug.Wait 30 seconds.Plug in AC.Power on.It reappears.Bios update... please someone tell me there is a fix for this. I am considering factoring this as being sold substandard goods and seeing if I can get it refunded on my credit card because I have so many issues with this laptop after 2 weeks.... It is crazy!!!$3200 SO DEPRESSED
