Newbie question: how do I properly shutdown my android 2.1 epad? If I hold the power button for only a few seconds, it goes to a blank screen but the blue light stays on, which I believe is just sleep mode. I don't get the little popup screen asking if I want to shutdown the device. So the only way I know to shutdown is to hold the on/off button for 10 seconds. Am I doing it the wrong way? Thanks for the help.
