So I found this video that shows you how to replace that power jack part - thing is where are you going to get one from?? On the other side of that motherboard you will see the battery sits and also the contacts now they should look and feel (don't be rough) quite solid on the board itself. Best get a magnifying glass and have a real close look at the soldered connections it they show any cracks then they are "dry" and need a touch of solder onto them. The new power jack assembly is just fixed back in.
Now one last thing a quick TIP
when I work on laptops the screws are so small and varied and are easily lost. So I get a large bath towel preferably white and duct tape it it the flat top - WHY because if you drop the tiny screws they will invariably skid off a hard surface and be lost forever more on the floor - the towel stops them in their tracks. Also keep the different sized screws separate like this bloke has - in pots I use pots with magnets stuck underneath to retain the little blighter's.
The bit in the video come in at a bout 7.30 minutes but to be sure watch it all and be careful with those ribbons cables they are fragile and the retaining clips are hard to see .
My pic shows a Toshiba but you can see the sort of retaining clips I mean they are fairly standard.
Last TIP take this chance to really give everything a good clean and reseat the cables .
