I took a couple of pictures and was ready to upload them to my computer. I plug in the USB cable into the camera (which is turned off) and then into the computer. Once I plug it into the computer I hear a click and it just shuts off. It is an HP so it has that blue light around the power button. Even though the comp was shut off, this light was still on. I tried holding down the power button but nothing happens. I think it may be the power supply but not sure. There is a green led that turns on whenever the power cable is plugged in. Any ideas on what the problem may be?
