Updated to Sierra, big mistake apparently. Mac won’t turn on. I’ve tried all tutorials, including the command/control/shift/power button options and it’s still just a black screen. Took all day to get it to a green light on the charger when there were no issues before. Nothing comes up on the screen, just black. Can’t remove the battery
MacBook Air, MD712LL/A
I am pretty sure I said at least 3 times the computer is not turning on at all, only black screen. Now I’ve gone two days without a computer that I need badly, because I updated it. Fix the problem and stop asking me if it turns on. It does not turn on! Nothing comes on the screen!

Try booting into Internet Recovery (command - option/alt - R on a restart). It is a slow process. This will install the OS that the computer shipped with. You can then try to upgrade from there.
If you live near an Apple Store, make a Genius Bar appointment to have the computer tested. Supposedly there is no charge for testing. Use 2nd link if not near an Apple Store or aren’t in the US. Hardware Repair - Keeping Confidential Data Safe
Take the original purchase receipt with you.
Nothing is restarting. Nothing even shows up on the screen after trying the reboot with command R. A file folder with a question mark appeared on the screen just 15 minutes ago. Hit command r and it shut off and won’t come on again
Two possibility, in case you haven’t tried already.
Power on with command+option+P+R to reset parameters ram. Then:
1) Turn on with shift key pressed.(safety mode).
or:
2)Turn on with option/alt key pressed; this start up to a volume (partition) selection, before using the macOS. If this do not start probably there is an he problem.
How about we STOP THE AUTO REPLIES AND FIX THE ISSUE! That idea won’t work. I just went there. Apple store is tying to charge me FOUR HUNDRED SEVENTY FIVE DOLLARS to send it in and “see” what’s wrong with it. I’m not paying anything when it was APPLE’S update that caused this! There’s no way this should be appropriate when I just bought this computer 4 months ago! Stop treating your customers like nothing. Give me an address of who I can send this to and will FIX it, because Apple is completely responsible for this. Maybe I should include all 4 of my old iPhone, my old MacBook and iPad along with it, as they were all rendered useless after pestering me every two hours to run an update and then they sucked! Fix it!
If you bought the computer new 4 months ago it should be under warranty. People have posted answers that should have fixed your problem or led to other troubleshooting options. If they didn't, then maybe your computer is having a hardware problem.
Your rant about stop the auto replies serves no purpose.
Good luck on getting any help.
It’s not under warranty it was refurbished. I know, I’ve heard that already. Apparently $800 for a computer makes it totally worth throwing in the trash after using it for 4 months. I don’t know where Apple thinks that people get all this money to hand over when it was perfectly fine before I installed the operating system. Shame on you Apple. This is the worst and most disgraceful way I could ever have been treated by a company whom I’ve handed thousands and thousands of dollars over to as it is. Disgusting
Boot to the Recovery Volume (command - R on a restart) and select Recovery Volume. Run Disk Utility and select First Aid. Then re-install the OS.
See this article and last paragraph also If your Mac won't turn on - Apple Support
It doesn’t turn on, black screen, nothing else when trying to turn it on. Also when hitting the buttons
If it was refurbished by Apple, it should be under warranty.
It wasn’t
Still waiting on the address of someone I can send this to, and I’m not paying $500 to do it. I can send it somewhere for $20. So where do I send it?
Mac won’t start after updating
