Q: My 2012 15" retina macbook pro won't turn on, sporadically

My macbook pro will go through phases of working fine, and not turning on AT ALL. I have reset the SMC, pRAM, bought a new charger, etc. But sometimes, I'll close my computer (which has excellent battery life, mind you) and it will, seemingly, die. No problem, right? Plug it in, start it up- NOPE! I'll plug it in for hours; until the charger turns green, even. And hold the power switch like there's no tomorrow. Trust me, all sorts of ways with different durations. It just will NOT turn on. No chime, no action with the fan. It just gets really hot after a few minutes. Then I'll leave it for a good 24 hour day alone. Only then, will I plug it in, and it will magically turn on. Bottom line- very worrisome, and untrustworthy problem I have. Are there any ideas?? Thanks in advance, everyone.

MacBook Pro with Retina display, OS X Yosemite (10.10.2)
