Years ago I had a box that did all sorts of peculiar things which I could
not explain... finally a guy suggested to me that I plug it into a different
circuit in the house and the issues went away. Turned out that the old
Fridge in the kitchen was on the same under-rated circuit for some reason
and when it kicked in it created one heckuva drop.
Fast Forward...
Out here in the sticks I get fluctuations daily in the bad weather months
and weekly in nice ones and 1 or 2 minute outages frequently... so get to
observe the UPS in action regularly.
Several months ago I was getting unexplained PC shutdowns with no power
outage to go along with peculiar error messages that had little or no common
theme except that the whole thing reminded me of the fridge incident only
that I now had shutdowns included. After an outage where the unit failed I
called the support folks for my UPS and told them that I must have a bad
unit. After a suggested test, they insisted only batteries even though I
pointed out that it did not always shut down (and made my case, I thought,
for the AVR being faulty). Being that this was a very expensive unit and
that batteries only cost 16 US bongos each I decided to take that $36 chance
first before a couple hundred if I could not get them to cover it... the new
batteries solved it. I do not know how AVR works, but I suspect that when
there is a drop it relies on the batteries for an instant, not only when
there is an outage???
At any rate... I would try the UPS if I were the original poster as well and
would throw in that one of these times it's going to corrupt a file or
driver or database when it happens and that is going to start popping up all
sorts of other issues as well... it's not a harmless occurrence sometimes.
