'''Note: After executing the shutdown command, the screen will briefly display "plymouth-poweroff.service" for approximately 1-2 seconds. If power is restored during this time, the system will fail to boot and will remain in a shutdown state until the next power outage and restoration. The probability of entering this dead zone is extremely low; it is not a concern for local use. However, for remote unattended use, please carefully evaluate the situation.'''

This is how a supercapacitor UPS starts discharging when fully charged (capacitor voltage around 5.2V), then restarts charging when the capacitor voltage drops below 3V, until it is fully charged (capacitor voltage around 5.2V).
