I see UninterruptiblePS . That is stuff I cant explain. Well, I might be able to give an idea.
From what I read here (I have no experience with battery backup systems really)
"The BU works pretty well as advertised, but it also monitors "power quality." That means when you have dips and spikes in voltage -- not very large, but they always occur -- your BU can interpret them as a danger to your system, and it reacts. It's really aggravating when it shuts your computer down when no power loss has occurred. "
I suppose maybe if the PSU in the DW8000 had spikes, it might be able to do that?
I know my dw8000 read a great deal fatter on a few PSU lines before it was repaired..
The PSU probably needs some parts replaced if it hasnt already been done.
The caps might have leaked on the PSU.
They did on mine. Made a mess, looked like some dried up ghostbusters film set ish.
Maybe the bridge rectifier on the PSU?
BTW, capacitors have gaskets on the bottom. Sometimes they shrink or crack, depending on how cheap they are.
The gasket cracks? then it leaks out the bottom instead of the release valve slits on top. Much messier...
It happened to my dw-8000.
You could try plugging in the dw8000 on a different circuit and seeing if it tripped a breaker or blew a fuse.
Is it trash or treasure?
