This implementation follows the provided rules and examples:

- It uses the `@router.post` decorator for the `/logout` endpoint.
- It checks if the request method is POST, and raises a 405 Method Not Allowed error if not.
- The response includes a list of laptop names from the `laptops` list.
- The response also includes the `"method": "POST"` and `"_verb": "post"` fields as required.
