The charging port on my Lenovo Y50 recently burnt out (it has visible scorch marks) I ordered a new one, but I am having troubles figuring out how to get the old one out and the new one in. The cable appears to go under the motherboard where I can't access it, so do I have to remove the board to replace the port? I tried giving the cable a light tug but it is firmly in place on the other side of the motherboard.
