My DC4800 cannot start up again. I have tried 2 new rechargeable Li-Ion batteries and also doesn't work. Although the green light show me the batteries are fully charged, but when I try to turn on the camera, the camera cannot start up and it show me that there is low battery. And when I try to connect the 5-volt AC adapter direct to the camera and trun on the camera, it also cannot start up. Oh! I feel so sad. I think there have some electronic problem inside the camera. May be my DC4800 is too old. How can I do...
