I thought that when APC BR1500GI's display went black (even with the fans still running) it is already in a shutdown state. This was not the case, it waited for a few more seconds until it totally went silent. At that time, I plugged the mains back and everything was working as expected :)<o:p></o:p></p></blockquote><p class=MsoNormal style='margin-bottom:12.0pt'>Unfortunately, electric utilities are not always so polite.
