Hi I have the same laptop and had the same thing happen. I am not a tech, just some dude that is handy and has "messed" with hardware for a bit. So this advise is "USE AT YOUR OWN RISK", I'm not responsible for anything. Well with that said here you go.\015\012
\015\012Remove the batter for safety. As you go keep the screws separated so you don't have to remember which is which when you put it back.\015\012
\015\012Flip the laptop over and you will find about a dozen screw holes labeled F7. You need to remove all of these to open the laptop. You'll find some running along the back edge of the laptop as well. \015\012
\015\012In the battery well, you'll find some more screws labeled F4, you should remove these as well.\015\012
\015\012There is a slider screw towards the right center of the machine that helps hold the cd bay in place, you don't have to remove this one, but you can in the even that you need to move the bay to gain better access to the DC jack.\015\012
\015\012Once you remove all the screws, flip the laptop up right. Open the screen as if you were going to use it. \015\012
\015\012Along the top of the keyboard, you will see that the bezel edge has a break away section the same with as the key board.\015\012
\015\012Using a small flat head screw driver pry it open from either the left or right side, and continue unclipping it across. \015\012
\015\012This will expose four very small screws. Remove them making sure to keep them safe, as they are holding your keyboard in place. Once you remove them, slowly seperate the keyboard from the body of the laptop. You will find a flat wire connected to the mother board from the keyboard. You can use a toothpick to slowly slide out the white edge from the brown connection bridge. Once you slide the white plastic peace away from the brown the wire will come out easily. BE CAREFUL with the wire since it is very fragile\015\012
\015\012Now you should have the keyboard separated from the laptop, put it in a safe flat place and continue.\015\012
\015\012On the left side hand of the laptop body is a card slot, use it as a finger hold to gently but firmly pry the laptop open. It is held together by clips running along both side edges and the front edge. These can be a little tough to open, so apply slow gentle force till you hear them pop open.\015\012
\015\012Before you pull it apart after unclipping it, use the same method used to remove the keyboard flat wire from the mother board connection on the three connections holding the top part of the machine to the motherboard. You'll find two towards the bottom center and one at the top left corner. Play close attention to the small flat white one as this is VERY fragile and the copper flanges at the end can bend very easily.\015\012
\015\012At this point you should be able to freely separate the top half (cover) of the pc from the bottom. Exposing the insides.\015\012
\015\012You'll be able to easy work with the dc jack now, in my case it was the plastic housing of the body of the laptop that broke. I held it in place with a dab of hot glue. \015\012
\015\012If you find that the CD drive is in your way, you can remove the two small black screws on either side of its copper connector, then lift the back of the bay up of the body and slow pull it and lift towards the left.\015\012
\015\012Work backwards to put it back together.
While I am not familiar with this particular model, most Toshiba laptops I have encountered have the DC jack soldered to the motherboard. If it has become disconnected, then reconnecting it is quite possible, but does require some skill. If you do not already have experience with soldering and/or PC repair, I would suggest asking a friend or family member who does.

In addition, if the laptop is still under warranty, I would speak to Toshiba support, as this problem is sometimes covered. Just back up your data first!
