2013 Macbook air 13" died suddenly during use. No low battery, no shutting down dialog, just blackness. The little orange-or-green light on the charger was black. Switching to another charger was the same. anything I can do?

2013 Macbook air 13" died suddenly during use. No low battery, no shutting down dialog, just blackness. The little orange-or-green light on the charger was black. Switching to another charger was the same. anything I can do? I tried the Hold-down-the-start-button-for-10-seconds in, no effect. We replaced the battery at the Apple Store a couple years ago. Could be a loose connection at the battery I suppose. Any ideas on what I can do, short of a trip this weekend to the Apple Store?
