I have had my tablet for over a year with no major issues. About a month ago it started freezing up A LOT. The last time it froze I held the power button until it went off...it hasn't charged since. I thought maybe it was the software but now when I hold the power button in the charger port and charger get hot. I read a forum that said try plugging it into the lap top so I tried that and while holding down the power button it shut my lap top off..this occurred twice so I'm sure it wasn't something else with the lap top....please help?!
