Hmmmmm I hadn't thought of it like that,....

I was actually buying this as a backup because
the computers etc still come up but from what
you've said they're vulnerable right now.

I think I'll do just that and replace the APC
and see if the light goes out or green.

In passing the number (2) Green Protection Circuitry
indicator in the center is green on mine.

I'll let you know what happens after I switch them.

Thanks,
Robert
