Back-UPS XS 1000 not keeping computer on during a 45 second power outage?

[Anonymous user]

Hi People,

I have a 1000VA unit and today we had a 45 second power outage. The UPS did not keep my computer on at all. Come to think of it, the last time we had a power bump (not even an outage) my computer shut down as well.

I just checked the battery connection and everything appeared fine. The battery shows 100% charged. The funny thing is if I unplug the UPS from the wall the battery kicks in fine and my computer stays on for several minutes with less than 20% battery usage.

Any ideas? Faulty circuit board, but good battery?

Unfortunately, my UPS is long out of warranty as it was purchased in 2003.

Hi,

During this outage, did the computer do a graceful shutdown or just a hard shutdown?

What is the total runtime reported by the software?

Your battery is 5 years old, right? I don't know if what you told us can happen to a worn out battery I mean, to output enough power for a few minutes and all of a suddend not provide enough power to run for a few seconds and then be "okay" again.

APC recomends changing the battery every three years...
