I was struggling with battery draining very often. I had tried battery saving softwares and full cycle recharges... Anything was working out. Once I had my battery almost 50% and suddenly the tablet restarted and never started up anymore. The screen started to blink, the Asus logo appeared and restarted, and so on and so on ... Even pressing the wake button for several seconds, it didn't seemed to shut it down. So the battery started to get hotter and hotter and I counld't shut down the tablet, so I figured out a way... Just opened the back cover and unplugged the battery connector and leaved it for 10 minutes.
After this procedure, my battery was reborn and now I have a brand new tablet.
To everyone who wants to open its tablet, remember to remove the SD card first before unsamble the back cover, otherwise you will damage your SD slot.
