I have a MacBook Air, 2013-era, that will not charge. Plugging it into the charger briefly causes the "battery is dead, plug in" graphic to show up on the screen. The connection seems pretty solid and I can't see any objects in the port or plug.
The light on the charger never lights up. Is there any way to eliminate the charger as the cause of the problem? I have no other machine to test it with.
