I found this old Canon Powershot A460 yesterday, and put newly bought EVEREADY AA batteries into it. But seeing this error everything looks fine in this CAM . I have also cleaned the battery components terminal inside and on camera door both using alcohol there is almost no corrosion, still can't use the camera. I tried so many times to turn it on but mostly it shows this error but eventually 1-2 times it turned on and even clicked 2 pictures with it at that time it shows low battery and after clicking pictures it can turned off showing the "Change the batteries" error . Can anyone help me with it ? Listing all possible methods to try .
