If for whatever reason either command returns an error then your sleep image likely doesn't exist, which would explain the problem.

Once the Mac restarts I would use the following command in terminal to check the size of the sleep image, it will likely be the same size as the amount of installed RAM in the Mac: ls -lh /private/var/vm/sleepimage

My first plan of action would be to remove the current sleep image using this command in terminal, you will be prompted to enter your admin password once you enter the command: sudo rm /private/var/vm/sleepimageįollowing that command I would restart the Mac using > Restart. I'm not familiar enough with noSleep to know if it removes/prevents this image but it wouldn't surprise me if this was the case since it's main function is to prevent the Mac from sleeping. Before attempting a more complex solution, charge your Mac to 100 with the adapter and use it for two hours with the charger connected. Hold the left Control + Option keys and the right Shift key for 7 seconds.
If the issue persists, follow these steps: Turn off your Mac. Try to unplug your Mac and see if it shuts down. Release the button, then power on your Mac after a few seconds. Power brick never gets warm so I don't think it's charging at all. Left it plugged in overnight and still won't boot up. This sleep image is located at /private/var/vm/sleepimage. Press and hold the power button for 10 seconds. Let my brand new 15' MacBook Pro's battery drain (not on purpose) and now it won't boot back up. Safe sleep relies on a functioning sleep image to store the contents of memory once power is lost. When your Mac loses power thanks to the battery draining it should enter Safe Sleep. If you are using a MacBook Air or MacBook Pro, you can charge your device and then press the Power button to see. You can check the power outlet to see whether the power supply is normal. In my opinion this sounds like a missing or corrupt sleep image. When your Mac computer goes to a black screen, the first thing you need to do is to check the power for your device.
