Hi everyone,
The strangest thing happened to me yesterday. My 2011 MBP was stuck with a black screen two days ago after I accidentally drained the battery (well I'm not sure how it happened exactly but whatever). I had tried everything, recycling by pressing power up to 30 seconds, then unplugged both power cord and battery to make sure it was trying to fresh start, even unplugged the hard drive, reset the SMC (the actual reset seemed to happen, but it did not change a thing), reset the NVRAM (that however did not go as usual). Battery fully recharged of course.
After all that it was still stuck, when I pressed power the sleep light would light up, fans started spinning (normal speed), for like 3 seconds, then it all shut down with a small *clic*, then back on again, forever. Screen remained black all the time. No chime, no "superdrive startup noise". To me it sounded as if it was still trying to wake up, with no success.
I googled, found everything I had tried already, and then I found this page: http://osxdaily.com/2017/04/02/fix-black-screen-wake-sleep-mac/ .
Went to the comments, and then I first tried what the second comment said, alt+n. Went as before, no change. Then I tried ctrl+N as the first comment said. I was convinced it wouldn't do anything as well, come on I've never read that before. I tried just to make sure I tried everything and be at peace with myself.
But the miracle happened, "superdrive startup noise", chime, and the mac starts normally. macOS didn't say anything happened (did not offer me to reopen apps). I then did an AHT to make sure, no problem detected.
And then the strangest is that I googled that combination, and I find no mention of it actually.
Of course it could always be a coincidence. I think I had that same problem (or a similar one) before and after a few days it resolved by itself.
