Hi all,

Tonight at 2:30am my wife's UPS started beeping. I went into the office
and found that the "on battery" LED from the APC Back-UPS CS 350 was on.
Power was on, and my UPS had not tripped. So, I turned it off and tried to
turn it back on again. It beeped once, but no LEDs lit up. I held the on
button down until it beeped and then the "on battery" LED lit up again,
followed shortly after by the "overload" LED and the continuous siren
associated with it.

I disconnected everything from it (even though everything was switched
off, many pieces of equipment still draw some power) and tried again with
the exact same results.

I connected it to a different wall outlet, the one that my computer and
UPS are on, with the exact same results.

I removed the battery and tried again: it beeps once then nothing. If I
hold the button down it emits a continuous tone and the "on battery" LED
lights up until I release it.

The "surge only" socket will still power things even when the UPS is off.

The "replace battery" LED has never come on (the battery was replaced
about 3 years ago under an APC recall of certain batteries, so it's not
terribly old and it's only been used maybe four times in those three years
while the system was powering down).

Is this UPS dead?

TIA,

Ari

Ari,
I work for an APC reseller. What is the exact part number of your unit?

I looked at the manual for the BK 350 unit for reference.
If you go to the APC website, you can download the manual if you have lost
you original one.
Here is what I used.

The problem may be that the circiut breaker on the UPS has tripped. The UPS
has a circuit breaker similar to a standard wall outlet. This trips if the
load supported by the UPS exceeds the rating of the outlet on the UPS. (Much
like running a dryer, hair dryer Computer and vacuum all on the same 15mp
circuit.)
You also didn't indicate if the items supported by the UPS are still being
powered or not. If they are NOT being powered, my bet would be the circuit
breaker.
If you reset that and the problem goes away, reduce the number of devices
supported by the UPS (or get a larger one).
If not, I is likely that the batteries need replacement. They typically last
3-5 years regardless of the number of times the unit has gone to battery.

Post what happens, I am curious as I havea similar unit in the basement
powering my router and VoIP adapter.
