If the camera won't turn on the mostly likely cause is defective batteries. Make sure batteries are charged and the battery contacts are clean.

If the battery holds its charge for only a short time or if the battery doesn't charge, it needs to be replaced. Remplacement de la batterie du Nikon Coolpix P4
