Surface Book 3 Nvidia Graphics card disappears after updates.

Hi Yosha#,

Thank you for reaching out to Microsoft Community.

I'm sorry to hear about what happened to your Surface Book 3. Please try to boot your device first to its UEFI screen and check if the dGPU option is enabled. Refer to this page for the steps on How to get to the UEFI settings. Once you are on the UEFI screen, go to Devices then look for dGPU. If it is already enabled, disable it for a few seconds then back to enabled. Choose Exit after then click Restart now.

If after the restart and still the NVIDIA Graphics card does not show, please run these steps below:

1: Run Surface Diagnostic Toolkit and check Windows Update

2: Update drivers and firmware

                               Check what is the current OS Build of your Windows version by going to Settings > System > About.

                               Go to Download driver and firmware for Surface, choose Surface Laptop 2 then click Download on the next page.

                               Choose the .msi file that matches your current OS Build and click Next.

                               After downloading, run and install the .msi then Restart.

3: Run System File Checker Tool in Windows 10

Yosha - I had this happen once on my SB3 13.5".  I undocked the tablet and re-docked it.  That seemed to make it re-appear in the device manager.  Good luck!

Having similar issue, on resumption from hibernation (yes I'm old school) the Nvidia GPU is no longer accessible to apps (everything runs on the Intel integrated), even in the NVidia Control Panel app the GPU is no longer accessible.  The only fix is a reboot.

I had the exact same problem with my new Surface Book 3 with Nvidia graphics. Worked great for a few weeks and then it completely disappeared. The Surface Diagnostic Toolkit was no help at all - said everything was fine. Tried rebooting. Tried undocking the display. Nothing worked.

Then installed the latest Surface Book 3 update (SurfaceBook3_Win10_18362_20.051.9924.0) that was available to download. Rebooted. Everything was fine again.

I had the same issue, its also happened before on Surface Book 2. On my SB3 you can either re-install or update to latest firmware.

Seems to be suspend/resume related. I also find if you perform a cold boot and hold down the power button for 10 seconds. Then power on as normal it magically appears.

@Microsoft - You need to get this bug fixed, not good for a 3k laptop.
