There is no difference. The Surface Connect charging connector can be plugged into the Surface Connect port in either direction.
For Surface Laptop Go models, charging is supported through the Surface Connect port and also through USB-C. When using the Surface Connect charger, the connector is designed to work either way, so the end does not need to face specifically toward the front or the back of the laptop.
A quick check that it is connected correctly:
- Plug the charger into the Surface Connect port.
- Make sure the connection feels secure.
- Check that the LED indicator on the tip of the charging connector is lit.
- In Windows, look at the battery icon on the right side of the taskbar. It should show a plug symbol while charging.
