I know the screen (Power on/off schedule) says "A power outage may invalidate the power-on schedule. If this happens, please power on your device manually"

So Sunday at 10am (local time) my system ran off battery for 5 seconds. Notifications show this.

So I have a Sunday night schedule at 10PM to power down the (F4-223) and back on at 100:59PM.
So Monday morning the unit was still off. So doing what it says above, I powered back on the F4-223.
What I don't understand is why? If the schedule was okay with a 5 second battery run, then as the schedule requested the unit shutdown at 10PM. What disappeared that it can't be brought back up according to the schedule?
Just curious?

Did the TNAS' Internet connection go offline and not come back due to the power outage? If so, it might be an NTP sync issue.

Maybe check the voltage of the RTC battery; it could be below the 3V required for normal function & require replacement.

If the scheduled startup failure persists, the latter is more likely the issue than the former.

I find this situation happening all the time, regardless of whether the mains power has "failed" or not. Sometimes the nas will not turn off in the evening and, likewise, not turn on in the morning. Some things I have noticed/done in part to remedy:
a) if more than one task is scheduled under Control Panel > Hardware > Power things go haywire more often than not. As a result I only use this function to schedule "Power On". (Every day in the am).
b) I run a command line 'shutdown' via Control Panel > Scheduled Tasks - as in every night (before midnight).

Note for @TMSupport: What I have not been able to do is use the command line messaging facility normally found within the 'shutdown' command to warn users that the system is going down. Is there anything within TOS that can message logged-on users via their GUI

Hi, is your network back to normal after power outage?

Everything was fine. I mean I saw the notification that unit ran on UPS for 5 seconds. Unit was functional all that day, then that night, the schedule shut down the unit but the schedule didn't bring it back up. I did try last night the same schedule, worked fine, off then later it came back on.
Only difference was there was no switching to battery.
I know the screen (Power on/off schedule) says "A power outage may invalidate the power-on schedule. If this happens, please power on your device manually" ***My question is why? Clearly the fact the GUI mentions this and I seemed to have proved it. Why could have possibly happened on the F4 during the 5 seconds on battery that would stop the power on schedule. Oh I had a thought, I will check the network switch to see if that is on the UPS as well. Maybe the 5 seconds was enough to trigger something on the F4. But like I said the F4 was fully functional (no issues) all during that day. Power blip was 10am and the schedule to power down at 10PM.

Update: We had power go out for 1 minute this morning. Both 223 and the 424 are on UPS, but only the 424 has the USB cable attached to the UPS.
So I did get the email from the 424 saying running on battery then later running back on line power. Both NAS did not lose power and were and still running fine. I will check later tonight to see if the scheduled shutdown on both happens. Of course I just remembered, the network switches the NAS's are connected to I can't remember if I have them on the UPS as well. I don't want to simulate another power outage to confirm that.
