Question about Casio EXILIM Card EX-S770 Digital Camera
From theslug on another thread. Thi worked great for me...
"Hi,I just found a soultion on another website and it appears to have worked for me.Apparently the battery loses it memory when fully discharged,to fix this take a 9v battery and place the terminals + to + and - to - with the camera battery for 30 seconds or so then put the battery back in the camera and charge as normal.I just did this and it seems to be charging and the red light is solid.hope this helps."

The theory behind the posted suggestion is that there is a chip on the battery that tells the charger 'here I am, I'm a valid battery, please give me juice.' That way the charger doesn't give any power to something that might blow up. But if the battery is totally dead, the chip can't answer the call, and so no juice is provided. Seems valid - don't know that I'd use 9V to do it, but a good approach is to jump it from another battery in the same 3.6V range.
I was having the same pwr up problem from a dead NP-20 battery, so used another 3.6V pack to dump some joules in and sure enough it's charging properly now (w/o the flashing red light). I assume it will complete and be fine again. So the warning - try not to let your LiIon battery packs get discharged and sit around.

So I have posted this on several others hopefully you still have your casio. I was having the same problem where my battery wouldnt charge. I bought a new charger and battery. That did not fix it. The battery is held in by a locking clip that supposedly holds it close to the metal conductors that the positive and negative touch the camera inside the casing. I took the battery out, looked inside where the battery sits and used the paper clip to somewhat bend the metal up so that it makes contact with the battery hence you get your charge. If the battery was dead you will not know until you charge it for about a half hr. The reason I knew it was the metal conductors was because i charged my battery with separate charger that I bought and put it in and it still did not work. I pushed the battery in the slot and held it ther while simaltaneuously pressing the power button. The camera came on...once I let go of the battery it turned off. Then I got the paperclip and fixed the battery connection. This also explains why it will continue to happen over time.
hope it's that simple for you
