I accidentally let the battery on my Nexus 7 run completely empty, and now it won't start up anymore even after charging overnight. How can I make it work again?
This is what happened in detail: My battery ran low, and I had no time to recharge it. I forgot about it, and found my tablet powered off. I attached it to a charger (the official wall-plug adaptor), waited a few minutes, and then turned it on. I expected it to be able to run from the cable like my phone, but it reported 0% battery and shut itself down immediately. I retried it after a slightly longer time. This time I didn't get to the home screen, but was shown a black and white animated battery icon. I pressed the power button, and the animation froze, and only disappeard after a long time (I put it away and discovered it was gone after a few hours). Since then I've been loading it for > 12 hours, but I haven't been able to get any response. The charger gets warm, but the tablet doesn't.
I've heard that once the battery is competely discharged, it only charges in "trickle mode" (that is normally used to top off a 98% loaded battery safely), and can take a very long time to become operative again. This would explain why the adapter gets warm but not the tablet. If this is true, is there any way to speed up charging?
