I plug my camera SD memory card into my computers card slot and nothing comes up on the screen. I then try putting the card into an adaptor that plugs into a port. Still nothing comes up on the screen. I then connect the cable that came with the camera into a port and bingo I get an indication that the camera has been connected and I can save my photo's to the computer. Has the card reader device been disabled when it was in for repair ? If so, how do I restore things ?![]()
