There is thread about this problem and guy was having the same problem as I and he said to me that only solution is to replace motherboard because it is somehow "fried". Here it is : https://forums.lenovo.com/t5/IdeaPad-Y-U-V-Z-and-P-series/Y580-Won-t-Boot-on-Battery/m-p/1784995#M13... ; There is no problem with the battery because when I boot with AC I can use laptop for about 3-4 hours with battery. I think my problem is this charging controller and I need to replace it. Could you please send me a few links on ebay, amazon or alibaba with free shipping to buy this particular mosfet.

Lenovo is doing remarkably little to address this. I, too, performed a battery reset and now have to jump through hoops to charge my battery. Up until this point I had been pleased with the computer other than the plastic cracking with age on a machine that has been babied. While I have the capability to perform the repair, I think Lenovo should fix all affected computers.
Thank you to the author, as I may end up doing this as a last resort.

Thanks or posting this Janslip! I just replaced my bad MOSFET with one from Digikey. Totally worth the work to not need a new motherboard. I suck at soldering so it took a while but now it's all working.

I used the part suggested above by Jansilp and it's working fine.
Here is the link for the alternate, FDS6681Z at Digikey--> http://www.digikey.com/product-detail/en/FDS6681Z/FDS6681ZCT-ND/1626210
