This is FAQ #49:

UPS does not return to AC mode and stays on battery till it dies.
This is FAQ #51:

https://networkupstools.org/docs/FAQ.html#_the_power_came_back_during_the_shutdown_but_before_the_ups_power_off_now_the_ups_does_not_reboot_and_my_computer_stays_off_how_can_i_fix_that

These are subtle edge cases, but apparently a lot of entry-level UPS models omit
the interface to control these two situations. As mentioned in both of the FAQ
explanations, you can work around this in software, or you can sell the UPS to
someone who annoys you, and look for one that provides the
"battery.charge.restart" NUT variable (Minimum battery level for UPS
restart after power-off) and the "shutdown.return" instant command.

In both cases, we have tried to collect NUT variable dumps and command listings
from NUT users here: https://networkupstools.org/ddl/

Note that this information is best-effort, and sometimes vendors change the
underlying firmware without changing the model name. There is no substitute for
testing when it comes to shutdown procedures, unfortunately.

result is that I already killed a disk.

UPS server.

[Nut-upsuser] UPS shuts down on NUT boot with low battery [APS Back-UPS RS 550G]

Thanks for the reply. However these two FAQ are unfortunately not describing the
situation.
- The first issue is that NUT switches off the UPS upon reboot on low battery
(not that it dies because of low battery)
- The second issue is that the UPS does not recognise being online again (not
that the PC does not restart)

omit the interface to control these two situations. As mentioned in both of the
FAQ explanations, you can work around this in software, or you can sell the UPS
to someone who annoys you, and look for one that provides the
"battery.charge.restart" NUT variable (Minimum battery level for UPS
restart after power-off) and the "shutdown.return" instant command.

returns, all boots, after 30 sec power is brutally cut, and so on. The net
result is that I already killed a disk.

network UPS server.

[Nut-upsuser] UPS shuts down on NUT boot with low battery [APC Back-UPS RS 550G]

My apologies, I misinterpreted "UPS does not return to AC mode" as the
UPS AC output, and did not carefully read the first issue.

However, I still maintain that there are a few features missing from this class
of UPS (or they are mapped to proprietary APC HID usages). It is possible that
the Synology shutdown strategy is using a different command.

With the devices powered from something other than the UPS under test, can you
grab a log from something like "/lib/nut/usbhid-ups -DDD -a ups -k
2>&1 | tee /tmp/APC_Back-UPS_RS_550G_shutdown.txt"? The usbhid-ups
driver selects one of several shutdown commands, and I think we will need at
least 3x -D to see that logic in the debug output. Please gzip the log before
emailing
