Fortunate that the power jack on your laptop is not soldered directly to the motherboard. On the ones that are, frequent damage occurs to the soldered connections, or even damage to the circuit board itself because of frequent pulling or sudden accidental strong jerking of the power cable. I do not know the model number of your particular laptop, but the video below should give you some idea of the work involved. In this video you will see a smaller pill organizer than the the one I provided a link too. I like the larger number of bays to segregate the screws in groups and order they were removed, no matter if they are perceived as the same size or not. That way when replacing the screws in reverse order you will be aware of how many should go back to that particular part or area. Also keep in mind that basic circuit boards and other parts are used in different products and that your laptop may have additional mounting screw holes that are not used. A good way to keep track of what is not used (if present) is to mark those holes with a black marker or felt tip pen. Another suggestion that might be helpful is to photograph the different stages of disassembly. That way if you are unsure how something is to be placed you can refer back to your images. Mark all cables and their specific connections with a unique mark.
Some or most of this friendly advice you may not need, but believe me you don't want to be putting your laptop back together and realize you are unsure what goes where or which way. (left right top or bottom)
