Hi,
I have a MacBook Pro and the magsafe cord had been tripped over one to many times and the ground became disconnected. I opened up the wire and I had just placed the wire on the ground ring. recently the MacBook will shut down as if it was just unplugged (btw I dont have a battery). I am going to get a new charger of course, but i also want to know if this is a problem cause by the cord's ground or if it is actually something with the laptop. Thank you.
