I've been using the same charger since I got the tablet for Christmas.Are you 100% sure the charger you're trying to use is working?
Have you held down the power button for over 10 seconds to do a hard power cycle?
Beyond that there isn't much more I can suggest. As I said before, my ROM doesn't touch the bootloader partition and my kernel runs at stock frequencies and voltages, so unless you've applied your own tweaks and potentially cooked something, it sounds like you've just gotten unlucky with hardware.
What's the hard power cycle do? Should I try that after it's charged up for a bit?
It's on and charging right now... I honestly have no idea what's going on. lol
