My MacBook Pro (I don't know the year, sorry. I'm guessing late 2012, or 2011) won't turn on. It was working perfectly fine yesterday, then today I went to turn it on and it didn't work, so I let it charge from ~4:30 to 8pm, and I tried to turn it on again and I got nothing. (Nothing at all) I tried to hold cntrl opt and r and it still didn't work. I tried holding it down for 10 seconds then adding the charger back and it still didn't work. (The charger is also green when it is plugged into the Mac). I got a new battery this September so I highly doubt it has anything to do with that.
