Change battery message

F/U to "ikes" comment, posted 10/06 - Suggestion seems to have worked for me, here's my history: Same msg. Set #1 died after a few days, nothing alarming. Set #2 and #3 didn't work; figured they were not charged. Set #4 were brand-new Duracell PLUS Alkalines dated 2012. These worked for a while under minimal (<90 shots over an hour) load. Typically I get well over 200 shots regardless of whether they're taken in an hour or over days. Note: My NiMH are all different brands, none were mixed with each other (I do this to ensure keeping "sets" of four). Alks died, same msg again. Waited, turned back on, worked a few more shots, same msg. Repeated a few times over next couple hours, finally would not turn on any more (just msg). However, I could preview just fine. Tried ikes' suggestion of previewing, then using shutter button instead of switch to get back into shooting mode. It worked! Lens came out, now I can turn on/off at will as usual on batteries the camera previously thought were dead! So, it seems to have fixed it but time will tell. (Not trusting this camera currently, even though it otherwise exceeds most of my needs.) Thanks, ikes... (I hope)

I am experiencing exactly the same problem with my Canon Powerhot S2IS. I tried the same thing to remedy it by cleaning off the contacts, but no luck. And it's not simply a cold weather problem. My camera does this with brand new Duracell batteries as well as with freshly recharged NMH batteries. What gives? I've had the camera for nealy 2 years and have taken excellent care of it.

I was just messing with my camera that had the same problem, my camera would allow me to view pictures with out the message popping up so i had the memory card out while it was on and put the card back in while the camera was still on and in view mode and pushed the button to take a picture and it switched modes without saying change the batteries. it said no memory card but i turned it off and back on and it was as good as new...probably a lucky fluke in my case but hopefully it will work for those with the same problem.
