Thank you for posting your inquiry here in Microsoft Community, Dr. Gökhan Tolun.
I'm sorry to hear that the GPU driver disappears after the device wakes up from hibernation. Please boot the device to the UEFI settings (turn off the device > press the volume up then the power button for 15 seconds) and check if the dGPU option is enabled, once you are on the UEFI settings go to Devicesthen look for dGPU. If it is already enabled, disable it for a few seconds then back to enabled. Choose Exitafter then click Restart now.
If the issue still persists after restarting the device, run the steps below:
- Run Surface Diagnostic Toolkit and make sure to complete the tasks.
- Check for new Windows updates. Go to Settings > Update & Security > Windows Update.
- Run the System File Checker.
- Install the drivers manually.
- Check the specific OS build of your Windows Settings> System> About.
- Download the driver and firmware for Surface, choose Surface Book 3 and click download on the next page.
- Please choose the .msi file that matches your current OS Build and click Next.
- After the download, runand installthe .msi then Restart the Surface Device.
