Battery ran out, and now my MacBook Pro can't turn on?

My MacBook Pro ran out of battery 2 days ago, so I charged it up for like 2 hours before opening it again. It does not turn on, it takes an hour but still on the white screen with the gray apple logo. I figured letting it "rest" for the night will do the trick but the next morning, still nothing happened.

I tried looking for answers and came across the SMC Reset where you hold the left Shift + Ctrl + Option + Power button all together while charging. I tried that and the LED light on my MagSafe adaptor did change, so I thought yey it worked. But no, it didn't. It still won't open! It's driving me crazy. I also tried the Disk Utility repair where you press and hold Command + R after the chime, but my S.M.A.R.T. status appears 'Verified' so nothing's wrong, I even clicked the Repair Disk and then it says nothing's wrong. So I shut it down, and tried opening it one more time, and it still doesn't open.

I tried resting it for a day and it still won't open. And now I think I made it worse, because when I try to open it, the white screen with the gray apple logo will pop up but then for about 3 minutes it will shut itself down. :( My MacBook's resting for about 2 days now.

Please help me!
