The camera does not turn on. What to do?

"i do not know if you try it,but put battery inside,put usb cable in ,connect it to PC ..(1st try to use usb 3.0)

and maybe your camera will switch on..idea is based on that some model of Fuji camera have inside firmware option to choose what type of battery is used..as if selection is set to wrong type,then camera will not switch on. Well,to pass that we will connect camera to pc ,to see if respond ,and even after some time usually can be can be turned on in many cases,or even batteries can be charged(depends of choice of batteries), but really is worth to try to see if camera will respond when is connected to pc.."
