Sounds more like a brownout, than a blackout. A brownout (horrible choice of words), is when the mains goes low voltage, rather than completely cuts out. It's possible for it to go far too low for electrical devices to run, but there might still be enough for things like LED pilot lights to still illuminate. Brownouts are a common cause of bogus repair jobs. The mains went low, and caused equipment to behave oddly, but it never went completely of, so people assume the equipment failed rather than the mains, and take it in for repair, when it didn't have anything wrong with it. Or, the low mains power upset the circuitry and it randomises settings in computerised gadgets (televisions, video recorders), so the clock goes funny and all the tuner settings go askew. All those gadgets really needed was to be turned off, completely, for a few seconds, and turned back on again. And perhaps go through the tuning process, again. But people take the gadget in for repair, and the serviceman finds nothing wrong with it. -- tim@localhost ~]$ uname -rsvp Linux 3.16.3-200.fc20.i686 #1 SMP Wed Sep 17 23:07:44 UTC 2014 i686 All mail to my mailbox is automatically deleted, there is no point trying to privately email me, I will only read messages posted to the public lists.
