Tablet correct but does not like to be discharged

I have the LG G-PAD 8.3 for 7 months, the performance is not extra-ordinary compared to my iPad Air (4 times more expensive, retail ...) Anyway, being a computer scientist, I needed a tablet Android for a small price and it does the job.
As against the battery of this tablet does not like to be discharged, so if it is completely empty, the tablet comes back more!
But Google is my friend and I found the solution that works if your LG G-PAD 8.3 seems asleep forever:
1 NON-connected tablet, press and hold the button for On-Off 10-12s
2-Connect the micro-USB power cord and release the power button, the display will light and the battery logo will appear, let connect about 3 hours to recharge ...
