My daughter's Asus memopad 7 was doing the exact same thing, wouldn't charge, wouldn't turn on...seemed dead. My wife was convinced we were going to have to make a purchase of a new tablet.... so since it seemed like a total loss, I decided to pop it open (which was fairly east once you get the first couple snaps to pop then work your way around) I unplugged the battery...which took me a few minute to figure out actually...because I was pulling down on the plug...and it pops up instead of down. I tinkered around with the foil that is attached to the back plate of the tablet....one of the "tabs" was crinkled down up near where the camera lens hole is...not sure if it is actually supposed to be making contact with anything... but looking at the board it seems several small pins are transferring energy through that foil... likely a chassis ground of some sort. I also noticed... the three contacts on the board where the Power button, volume up, and volume down buttons land on the board...had little black squares covering the top of the contact...there is sort of a small nipple on top of the contact...only the square on the power button contact had slid down so that the button wouldn't be hitting that little square. I am not sure what the little squares are....perhaps shims? Maybe the case was designed badly and the power button won't push the contact down without the shim? Who knows..I peeled it, and placed it back on top of the contact like the other two were. After fiddling around a bit....I plugged the battery back in...snapped the rear cover back on, pressed the power button and a red battery light flashed.... I plugged it in and it indicated that it was charging. After about half an hour, I went in and pushed the power button...the tablet booted right up. Now...what actually fixed it? I don't know.... my guess however, is that leaving the battery unplugged while I was messing around with other stuff, allowed to board to completely discharge and reset it. So that is what I would try first....pop the back off, unplug the battery and let it sit for 10 or 15 minutes...plug it back in, pop the back of the tablet on and plug the charger in. I have fixed many a laptop by simply popping the battery out...then pushing the power button and holding it for a few seconds... and I was pushing the power button tab on the board while I was messing with the little black square and had the battery unplugged. Hope this helps...and good luck!!
