if you connect your laptop to the camera via usb cable it should automatically detect that your device is a camera. if a window does not pop up try looking in my computer. perhaps you have autoplay turned off.
if your memory card reader slot doesnt work then you might not have the drivers for it installed. go to hp's website and look up your laptop model and get the driver set.
also remember that your camera most likely needs to be on and not powered off to transfer.
