This is FAQ #49: https://networkupstools.org/docs/FAQ.html#_my_ups_powers_up_immediately_after_a_power_failure_instead_of_waiting_for_the_batteries_to_recharge

> 	• If power returns after the system has started the shutdown sequence, the 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. 

(If you get an error from the mailing list about the message size, please try turning off HTML posting, and gzip any log files.)
