    Macbook Air 2017 startup problem
    After shutdown my MacBook Air by apple menu or power button I can't restart normally (by power button).

    I need to unplug and replug the battery, after that I plug the power cable and the macbook will automatically restart.

    I try to reset SMC, NVRAM and reinstall macOS and nothing, always the same problem.

    I don't know what to do. Any idea ? The keyboard works cause after shutdown the Mac, when I press the power button I can see the power led changing state.

    Maybe I should replace the battery ?

    I don't know if this will be able to detect an issue, but give Apple Diagnostics, How to use Apple Diagnostics on your Mac - Apple Support, a try?

    I am a bit confused. Removing the battery is a rather lengthy job requiring the removal of the case. So are you removing all the case screws to take out and reinstall the battery? Wow.

    In addition to what ferrarr suggested - when you do get it to boot check the battery under About This Mac-> System Report-> Power->Health Information. That should give you a look at how many cycles and if it is supposedly running normal.

    Recommend using Onyx to clean your Mac.

    The result is normal and 185 cycles. Yes I removed the case and just unplug replug the battery. Actually I don't shutdown the Mac, I just close the screen and when I reopen it, he automatically leave the sleep mode. Some times I don't know why, its doesn't work, maybe its a deep sleep mode.

    What version of OS X are you running? I do know there was a patch for Mojave that dealt with coming out of sleep issues.

    Do you have AppleCare for this MBA? If so, you should let Apple take care of this for you or replace the MBA.

    The apple store can run a more in depth diagnostics and at least give you an idea. As far as I know it is still free.

    Try disabling Power Nap in Energy Settings, this has been a restart problem for some. Of course that is not a fix just a workaround and there is obviously a problem that needs to be fixed but just try it as an elimination process and let us know if that makes any difference.
    I used to be conceited but now I'm perfect.
