When you push down the outside sleep/lock button, on the inside their is a shiny thin round piece of metal that causes the round on/off "button" on the flex cable to toggle on and off.
The sleep/lock button at the top right of the iPod touch 4 has a flex cable inside which is wrapped around a piece of metal held in by two screws. If you carefully, without tearing the flex cable, remove it from the inside you will see that under the plastic power button (the one you press on top of the ipod, but on the inside) you will see the thin shiny rectangular with rounded ends piece of metal.

If you pull back the flex cable and the piece of metal it is connected to, you should be able to push the silver looking round metal piece back UP into place and seat it properly under the bottom of the sleep/lock button.

It sounds confusing, but take a look and you can figure it out pretty quickly.
If the ipod was dropped severely and the back casing is really dinged in, you may need to get someone to transfer everything over to a new back case. This requires experience and soldering skills.
