Surface Book 3 Nvidia Graphics card disappears after updates.

Hello

Both myself and a friend were having this same issue with Surface Book 3 Nvidia Graphics card (driver) loss. We both tried various fixes mentioned here and some worked but only transitorily. Finally, using a third party driver updater... I discovered that the Nvidia driver ...Microsoft still had on the laptop after all the Windows and System Updates were complete .....was still ***** 6 months older***** than the most (current driver version) on the Nvidia website.  Both of us updated to the latest Nvidia driver.. and this completely solved all problems. 

Perhaps a mutual sharing of updates by Microsoft and Nvidia would be in order.

I agree. I am getting very tired of this issue.  Some games can handle losing the dGPU while running and a "Scan for Hardware Changes" in the device manager brings it back.  But others games cannot.  There are days I feel like I wasted a lot of money on this thing.

I think everyone is missing the point. This should NEVER happen. If my desktop simply just decided to detach the graphics card and then I had to reboot it just to get the video back would infuriate me. However, because we happen to have the main intel GPU to fall back on we merely accept the behavior and go through whatever "fix" we have become accustomed to in order to keep working is just crazy. 

The more I hear of it I am beginning to believe it has something to do with the connections from the NVidia GPU. I don't seem to have the issue as often if there isn't an external monitor connected to my machine. The problem is that to prove it you have to take apart the bottom section. Unfortunately that means you have most likely destroyed your machine since there is no way to take it apart without damaging the case. 

Regardless, this is an abysmal design flaw and I wonder if Microsoft will EVER admit and fix it.

For some reason it seems to be degenerative for me. I used to be able to play some games and not others, but now any game that uses the nvidia hangs mid-load, when I get the 'detached' sound. I can scan to find it again, but it just happens again. I'm crossing my fingers that when they fix the screen blackouts it fixes this as well. A little naive perhaps. I'll give it a little bit longer and just send it for a replacement, but I'd rather not.

This is NOT a fix or the problem solved, it is a workaround. Having to detach, reboot, and use any other workaround is either a design flaw or a bug. In more than one use case having to go through any of these workarounds is plain and simple disruptive at the very minumun.
