The most common problem is a bad battery.
You need to buy two new NiMH AA batteries and charge them before putting them in the camera.

I just upgraded to a Canon Power Shot A710 from an older Canon digital camera. I had been successfully using rechargeable batteries with my other camera for several hundred shots/charge. With the 710, the battery light comes on as soon as I put newly charged batteries in and the newly charged batteries only give me 30-50 shots. Anyone have any advice? Is it the camera?
