Sometimes when I switch the camera on I simply get the empty battery flashing icon on the otherwise empty top display - even with a full battery. I remove the battery and replace it with another charged unit and all is well. I put the original battery back and still all is well. It is not the battery as I have marked it and the problem reoccurred with a different unit. So far the above remedy has worked but I am off to India next year and i don't want the camera to fold on me there.
Anyone ever seen this before?
