The silver contact to hold the solder is gone,causing it not to have solid contact.How can I fix this?
Sorry the pic isn't that good.But its the bottom center if you can't tell

Sorry, that picture is too blurry and unhelpful.

Is the lead for the component still there? Can you solder?

It was to show their is nothing to hold the hot pin in when soldering.I believe its the lead,if so its not their.In the pic you can see 5 spots to solder the jack in,but the 6th in the bottom center is gone.
After rewording about 4-5 times on google,I think I found something.

Maybe I just need to run a lil solder in the ring for the +.On the 2nd link it shows how to replace a internal copper sleeve,if was pulled out by accident.
Is that on all,most,or mostly older MOBOs?I don't think mine ever had one in it to start with.Its a late 2007 laptop.

I will take a couple more pics,they are from a cell and its hard to show detail.

1st pic is the top side of mobo(white square),2nd is the bottem.I tried.Their is still solder on rest of the 5.Just haven't got around to removing it yet.Want to try and get this hot pin figured out first.

The picture is too blurry for me to see well enough, but it appears that there should be only five leads off that connector. The sixth hole is just a placeholder.

Ah, I see new pictures. Still blurry, but there are five definite leads there. Likely the middle one is your center pin (+ pin). As long as you have the correct replacement connector, you just need to solder those five points. Use a little solder braid to clear those holes before trying to install the new connector.

Dang! On further consideration, it does look like that sixth lead is soldered on the top side only... can you confirm that there is solder on the top side of the board for that sixth lead? If so, then you will have to do that again. The board is not designed to take solder on that lead on the bottom, from what I see in the picture.

Thanks dngrsone,I thought the actual pin sticking out the back needs to be soldered in too though.Yeah I got desolder braid and a manual mini pump.Braid works faster.
 
Yes their seems to be some on the top,but its so fine you have to look hard.And their definatly isn't any on the bottom.
 
Then it is only reasonable to put a little solder on the topside of the board for that pin.

Be sure to cut the lead flush with the bottom of the board after you install it, so that it doesn't make contact with anything else.
