Since hard reboot and a USB recovery attempt were already tried, the remaining supported next steps are:
- Try the basic power/start checks once more only if they were not done exactly this way:
- Disconnect all accessories, including USB devices, SD cards, external displays, Type Cover, and any dock.
- Connect the power supply designed for Surface.
- Charge for at least 15 minutes.
- Press Windows logo key + Ctrl + Shift + B.
- Then press and hold the power button until the logo screen appears, about 20 seconds.
- If the device is still stuck on the Windows logo screen after that, the documented self-service step is to start it with a USB recovery drive:
- Shut down Surface.
- Insert the USB recovery drive.
- Press and hold volume-down while pressing and releasing power.
- When the Surface logo appears, release volume-down.
- If Windows still does not start after the USB recovery process, the next documented action is service or repair.
- Send to Microsoft by creating a service order and printing a shipping label.
- Get in-person support through an Authorized Service Provider where available.
- If the device is organization-owned, contact the IT helpdesk or admin.
- For additional support, use the Surface app or a web browser and select Get Help.
The context does not provide any further self-service fix beyond forced restart, USB recovery, and repair/support escalation for a Surface Pro 6 that remains stuck on the logo screen.
