Try replacing your lithium battery. I was just reading about this yesterday. The manual says it was installed upon manufacture, not on purchase, and to be aware that it could be low.
Just an Idea.
Good Luck

I just got an A510 about 3 days ago. However, I experieced a "replace battery" message after only about 20-30 shots. I think the battery chamber is not properly designed and made. After I press the battery and close the battery cover, I can go for another 50 shots with flash on. Then the message appears again. There is no clear indicator of the batter power until the red sign warning about low battery which is incorrect as I mentioned above.
