Why doesn't my Samsung Galaxy Y Duos S6102 power on?

My Phone doesn't turn on... I left my low battery phone in the table. And a few days i charge it and after it charge i check my phone and then this happened, it wont turn on or do anything. First i though it was my charger but when i tried it to my other phone, it works fine. I tried holding the power bottom for 10-12 sec and it doesn't work. I tried removing the battery for 50-60 sec and reinsert it again but it doesn't work. I just got this phone a few months back. No cracks in the screen, no anything. I didn't drop it in the water or any liquid surfaces.
