There are two micro-switches on the camera. One is in the door frame of the battery compartment. One is in the door frame of the memory card compartment. The doors must be closed and fit correctly or the camera will not power on.
Also, are you using any 3rd party accessories on this camera (in particular, are you using a "battery grip"?)
