Given the symptoms and the steps already tried, the remaining supported actions are limited.
- Disconnect all accessories, including USB devices, external displays, Type Cover, and any dock.
- Use the power supply designed for the Surface and leave it connected for at least 15 minutes. A solid white light on the official charger indicates the connector light is on, which means the power connector is detecting a connection.
- Try the display wake shortcut with a keyboard attached: Windows key + Ctrl + Shift + B.
- Try another forced restart: press and hold the power button until the logo screen appears, about 20 seconds. If Windows is reachable at any point, use Start > Power > Shut down, then hold the power button for 20 seconds.
- If charging through USB-C, confirm the charger is USB-C PD and provides at least the same wattage as the power supply designed for the Surface.
Important: do not remove the battery driver on Surface Pro X because the documented warning says restoring it requires a full reset. That warning is specific to Surface Pro X, not Surface Laptop 7, and no context here confirms that step for this exact model in a no-boot state.
Based on the documented guidance, if the device still will not charge or start after the above checks, the next step is service. Since a warranty service order is already open, that aligns with the supported path. The Microsoft Q&A content in the context also describes similar battery/power behavior as likely hardware-related rather than a Windows issue.
