I am looking for any help and tips:
It's about the APC BP 420 (Back UPS pro system)) it stopped working 10 days ago, in
fact I heard some beeps at the reboot, first I thought it was my computer but after
looking a little closer I saw the input circuit breaker tripped, I tried to reset it but
it won't it stays in upper position loose.
the self test works and no lights other than the green one is on.
what should I do to be able to use my BP 420 again?
now I have my pc plugged into a regular APC surge protector and everything works fine.
the APC was not even overloaded:
on it there are:
Pentium 75 upgraded with a pentium 200
Monitor 14" color
USR external modem
that's it, was working fine before the incident.
Thanks for any input and ways to repair it!
