Been using my Tf810 for a couple of weeks now. I have generally been very happy with it, but today it just decided to crap out on me. Won't start up at all, not sure why, battery is fully charged, but when I hold down the power button all I get is a buzz that indicates it's trying to turn on and then nothing after that. Really disappointing as I loved this thing. Anyone have any ideas on a fix? I'm gonna call up asus tomorrow (I think my warranty through Adorama is over) and see about getting a replacement. Really upset about this.
