Laptop wont turn on? Stuck on restart?

Hello Sasha!

The thing with ….charging for at least 8 hours…, it concerns those units which intermittently shuts down even though the battery shows a remaining charge . But now your machine is won’t power on, so it isn’t our case.

So, first we’re going to do is SMC reset.

1.Shut down you mac by holding power button.

2.Press and hold the right Shift key, the left Option key, and the left Control key for 7 seconds. Your Mac might turn on and show the Apple logo on its display. Keep holding those keys while you also press and hold the power button for another 7 seconds. If your Mac turned on when you first pressed the keys, it turns off at this point.

3.Release all three keys and the power button, then wait a few seconds.

4.Press the power button again to turn on your Mac.

If, this doesn’t help. We can try to restore your mac’s firmware but we’ll need to boot a first mac to DFU mode, second mac with Apple configurator 2 installed on it, and a cable to connect them with each other.

But just try to reset SMC, if it won’t do the trick just take your mac to apple authorized service provider it’s the best option, because you have the apple’s one year limited warranty. Let the technicians do their work :)
