I have a MacBook Pro (Retina, 15-inch, Mid 2015). Now after three years of use, the charger isn't responding to being plugged in. I tried to reset the SMC by holding down the left side shift control option and the power key but no luck.
Is it possible to charge my MacBook using Thunderbolt 2 ports or USB 3 ports? I have seen some videos on Youtube people charging their device using these but I am not sure.
