EyeMWing,
This may be of no help but ............? How long have you had the camera - have you had (previous) battery experience with it?
Brand new Powershot A550; same behavior as your A530 with "Ultra Pro" and "Powerex" NiMH AA's. Tried regular and rechargeable alkalines, couple of brands - same problem.
Camera back to Canon who reported "no fault found" - but camera didn't know that!
So, looked around, tried "Rayovac Hybrid" and operation has been perfect for well over two years, fairly regular use. A battery the camera likes!
Apparently, some of these cameras are extremely sensitive to battery differences (dimensions or whatever). Few cameras in many of one model may behave idiosyncratically. Maybe if you try other batteries (and perhaps your patience) you could get lucky.
Perhaps your A530 is not "shot" - this info may be of no use but a having dead camera can feel like
..... so had to respond.
Best to you!
P.S. Camera refuses to eat what it doesn't like, to this day!
