Recently I was given a Kodak camera that was a few months old but was not working. It had fallen off a chair and that fall had rendered it DOA. After taking it apart to look inside I discovered that the battery contact fingers were not touching the battery. The fix was easy, just bend the battery contact fingers up. That can be done without taking the camera apart.
Just in case you want a peak inside the camera, here is a picture with the front and back covers removed.
