How do I dissasemble nikon L105 - Nikon Coolpix L105 12.1mp 15x Optical Zoom 720p Hd Movie Recording Flash

You don't! That is a job for a qualified camera repair man. Trust me. I know what I am talking about. You will have a pile of parts that you cannot reassemble when you are done and on a Coolpix, the resulting repair bill will mushroom to more then the replacement cost of the camera. Cameras and lenses come apart fairly easily, but often cannot be reassembled by following a simple reverse order of the process.
