Will not let me upload pics says camera not connected to usb port
The error indicates that the computer is not getting an understandable signal from the camera (or dock if you are using one). The solution will be in discovering why the signal isn't getting through, or deciding that the camera or dock is defective.
Verify that the camera battery is charged. Then turn all devices (computer, dock and camera) off. Remove every cable and wire between computer and camera. Unplug power to the dock.
Examine each connection carefully. Look for dirt, bent pins, loose connections, or anything "strange". Look at the bottom of camera too, where it sits on the dock.
Reconnect the wires and cables, power everything up and see if any improvement.
If no improvement and you have WinXP or Vista, Do a System Restore back to a date when the camera connection was working. Restart and check for improvement.
If no improvement, check computer update history. Have any Microsoft updates been applied since the last time the camera connection worked? If so back them off and check for improvement.
If no improvement or no MS updates, decide that the camera or dock are defective and return them. Unfortunately, electronics sometimes fail. If you like the camera, give a replacement a chance.
Take the memory card out of the camera and copy the pics through a card reader.
