So it would appear that my magsafe cord has a wee short in it. At least that's what I'm guessing. If it flexes in any direction the little light on the connector goes off and it is no longer charging. If its sitting still, then no problems. I have to unplug the whole thing from the wall and then reattach it to get it to charge again. Now, I don't know if this is a coincidence, but my batter wont charge over 97% unless I unhook it from the power supply and run the battery down, then it will charge up to 100%. However the next time I look at it, it will be right back at 97% again. This is a mid-2010 MBP. Any suggestions or am I just stuck shelling out $80 for a new charger?
