Started having issues from the first day of buying this device. It powers off with full charge.  Support process via Amazon/Dell was a mess to say the least. A few days ago the screen started showing some funny images ans today the screen refuses to show.Called Amazon and was rudely told to meet Dell. Dell said the warranty expired even before I  bought it. What about the one year warranty? Amazon says this is covered by them, that they only support 90 days. Spent almost 500 for this.
