So my N7 died yesterday while at nearly full battery. It was running a game, made a horrible buzzing noise instead of the game's usual sound effects, then I tried to turn it off with a long press to reset it, and eventually it did turn off after a number of "app X is not responding" messages. The screen went black, and it hasn't been back since. Plugging in the charger shows no response. No backlight, no flicker, no noise. Deadsky. No combination of power+volume buttons, at any length of time (have tried for 30-45 seconds, 2 minutes, and once desperately for 5+ minutes) seems to help. Battery is well connected internally, and I have tried disconnecting and reconnecting it. Stock charger does nothing much, and plugging into PC USB again no response. There does seem to be some power draw, as the battery grows warm when plugged into the charger for extended periods. Have left it unattended and not charging, and then charging for hours, without result. I purchased it from newegg, so I'm guessing I'm stuck going to ASUS for an RMA. Any tips, hints, advice?
