My A500 Iconia seemingly chooses to completely power off at random. Just recently I was sitting at my desk and powered it on (it had powered off sometime overnight while I was charging it) because I planned on using it in a few minutes. I walked away for about 15-20 minutes and it had shut itself all the way off again. That leads me to my second issue: Powering on. Supposedly this is supposed work by holding the power button for 2 seconds, right? Mine usually takes me two or three tries of holding it for upwards of 5-10 seconds before it finally gives me the "bzzt" letting me know that it's going to let me turn it on. It has never actually FAILED to turn on, but it is annoying that I have to sit there sometimes pushing the button for 10 seconds only to have to release and try again just to get it to turn on. Does anybody else have this issue, and if you do, was there anything you did to correct it? I'm hesitant to get bring it in for "warranty" work because I dont want to be without it for a month, but I also don't have to worry about these issues forever... any advice?
