Do both charging ports need to be soldered?

The chromebook doesn't charge, light that indicates that doesn't show, so I thought maybe it needed a charging port replacement, or maybe the battery. The charger works, tested it on different devices. I want to know if both charging ports needed to be soldered, or I can just easily replace one of them, because I have no soldering experience. My Chromebook model is 14-da0012dx but the internals look very similar in the guide.
