Why won't my Nikon N80 turn on?

Hi Maegan, often times when carrying your camera with you throughout the day, or even just having it sitting at home, dust and other foreign objects can become imbedded within the camera. Try gently clearing out all the spaces by the power switch to get rid of any dirt or dust that may have accumulated throughout your travels and make sure the power switch can move freely. While you mentioned that you had tried charging the batteries, I would recommend that you try other batteries and make sure they are each in their correct chambers as well as making sure the chambers are free of any debris.
