First off, if the silver wire disconnects, you CAN put it back together.
Just take the bottom off, look under the CD tray(its in a small crack, hard to see without a flashlight) and you will find a little plug in that is just big enough for the silver wire.
Get it in there, blue side up(i think) and after this DO NO PULL ON IT WITH ANY FORCE, gently move it around so it will not fall out again.
Also use a pair of tweezers to push it in further, you will know if it is in far enough if you plug it in and turn it on and you have power to your eject and reset button.
