Camera won't turn on, won't charge. (by 5 users)

I bought a Casio Exilim EX-S770. I have had the camera for almost a year with no problems. I just got done taking a picture and docked it to add the picture to my computer.... the USB light will come on when it is docked but not the charge light. My camera won't turn on either.... at all. I unplugged the dock from the power source and the USB light is still on as long as the camera is on the dock. It was working fine and now nothing. I know the battery wasn't dead when I set it up to transfer the files. I am also getting a message that states: USB Device Not Recognized One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it. For assistance in solving this problem click this message.... and then the message says: Unknown device (now I have more than one USB port on my computer and have tried it in all 4 of them) It also says: try reconnecting the device. If windows still does not recognize it, replace the device. I don't understand, it seems like if it was my USB dock or even the USB cable, the camera would still turn on but I get nothing.
