I keep getting a message when battery is low and runs of power. When i try to turn on the tabletI get a blue screen that asks to reboot and a series of requests to update in Various ways. When I reboot it comes on and is glitchy. It turns on in safe mode. When I check out the requests I get a Scary green screen with a lot of writing and symbols I don't understand. Also I can't get the information for the nook that on the tablet, it won't open. Very much. not a skilled user of this new technology stuff. Of age to remember as an adult getting my first computer with no Internet
