The two times the power went out in my area this year, my Mini PC never came back on. I had to open it up and disconnect the CMOS battery for hours to get it to work again.
Is there any way to prevent it from crashing again when it is suddenly turned off?

    srpantano Your MINI PC doesn’t boot up after the power down, because it triggered the protection system, so you need to restore the CMOS.
    Next time, you can try to clear the CMOS instead of taking out the battery.
    Please turn off the PC , unplug the power supply, and put the pin in the pinhole and press it for about 10 seconds , restart the PC after ten minutes.
