You haven’t given us much info about the Mac. Which MacBook model? Does it have a MagSafe charging port on the left side, would be closest to the upper left side? From your comment, “left bottom port” not at all sure if you mean the MagSafe connection, or one of the USB-C connections, if it is a newer Mac. If it does charge in the MagSafe connection, then charge it there, as it is supposed to do . . . it’s fine in that case. Otherwise agree with the reply that say get it to the AppleStore - or at least an Apple Authorized repair source.
