Sigh, another battery problem. Let me guess, somehow manage to overdischarge and battery voltage went south near 0v
It reminds me of Galaxy Tab 3 7.0.
The Tab refuse to turn on after the battery was depleted. No screen activity, no LED blinking, noting happen when the cable and the charger is connected, even after several hours plugged.
Physically unplug and replug the battery connector inside the Tab could trick the firmware to get it charge the battery and get its life again.
It also use non-removable battery, so the workaround is a little bit invasive method.
