If you've never taken apart a notebook computer before, here's some guidelines to stick by:
1: Remove everything you can that's large right away (hdd, ram, etc)
2: Place your screws on a mat or large magnet in the position you took them out of. Often manufacturers will use different screw lengths in different places - make sure they all go back the same way. I have several Cisco switch mounting magnets that I use.
3: If it doesn't move or come apart, you missed a screw.
4: If you just can't find a screw and it still won't move, take a breathe, get a flashlight, and spend 5 minutes just looking at the notebook. Search for seams, clips, hidden holes, covered parts, etc.
5: Remember what order you took things apart in. Often they only go back that way.
6: Small flathead screwdrivers are your friends. Manufacturers love to use clipping chassis designs, and these drivers are perfect to wedge them apart.
EDIT: oh, and about the power connector. It's just three leads soldered onto your board. Go to radioshack, get a compatible connector, desolder your old one off, and solder your new one on. good as new.
Thanks for the quick reply. I took apart a Toshiba and reassembled it a few months ago. It has been sitting around a few years after my wife spilled coffee in it. I need to find a replacement for it down the road and get it working.
