I had the same problem. I brought it to Radio Shack and the guy said it was not a problem and I just had to leave it in the charger for a day. I did, and before I knew it, my camera was back to normal. Try this method, but if it does not work call Tech Support.
If the charger and new Battey does not fix the blinking probem with the packaged charge /batter fro the 770. Be sure Casio will here from me as 6 months of limited use should not cause the meltdown of the manufactued - enclosed/included product companion specifically the Lith-IN batt and charger. Shame on you Casio. Casio and In house Law associates-You'll here from me if China/eBay can't fix my issue after-being forced to buy the after-market packaged charger and battery that was initially included with the casio exillim 770 purchased n Feb 2007- problems began Oct 2007. Thus I must take this chance to purchase an after maret item (on eBay) in hopes it can perform as well as your original inclusion of battery and charger with purchase of the Cssio Exillim 770. Please advise your thoughts and possible corrections to this issue as I am clearly not the only consumer with this unfortunate grievance. PS Wuld Love to use this camera on my NYC trip Oct 10-13.

Okay, the same thing happened to me. I ordered a new battery and that was not the problem since the same blinking light was haunting me! So I bought a wall charger for the battery alone and then it worked again on the original docking station. Apparently it will not recognize a completely dead battery on the docking station. It makes no sense but it worked for me. So good luck to you!
Call Casio Tech Support and tell them what's going on. They will tell you that you can send in your battery, charger and camera and Casio will send you a new battery after you send yours in. They will also tell you where to send your stuff. The only bad thing is that you will have to pay the shipping to get your stuff to Casio.
