[ubuntu] Laptop won't charge

http://ubuntuforums.org – Hey everyone, don't know if this is the right place to post so sorry in advance. I have a Gateway M520 from a while back, and it just won't charge. When I plug in the power cord, it is loose and wiggles around. I have to hold it in a certain position for the "charge" light to light on, but as soon as I let go, the light goes off. Is this a problem with the cord or the DC jack? And would it require replacing the DC or should I resolder it? Appreciate any help. (Hardware)
