So this is the model that I have. It's pretty old and I know it should be replaced. I intend to do so in the near future.

https://www.apc.com/shop/ca/en/products/APC-Back-UPS-ES-750-VA-120-VAC/P-BE750G

In the meantime though, yesterday the power went off. I have the PowerChute software installed and had it set to run for 5 minutes before it shuts the computer down. I waited a couple of minutes to see if the power would come on and when it didn't I went to shut it down myself and it was already off. I get the impression it drained completely perhaps before the 5 minutes was up.

So my question is, is there a way to see if the software actually shut it down properly as intended or if for some reason it didn't do it's job and resulted in a hard shutdown? I looked all through the software and couldn't see that information anywhere. I also checked the Event Viewer and there was nothing there to indicate it shut the computer down either.

The battey took a really long time to recharge after that event. By the end of the day yesterday it was just over 50% and today it's finally at 100% and showed an estimated battery time of 83 minutes before I ran a self-test which it passed and now the estimated battey time has dropped to 60 minutes and the charge is only at 73% so it's charging again. I've also lowered the run time from 5 minutes down to 3 minutes.

Aside from my question about history to show a shutdown, is the above information showing signs of imminent failure or could it still be doing its job properly?

Karen check the event viewer. It should note an unexpected shutdown [as long as you know the approx time the pw failure occurred]

Once the battery is at 100% unplug the UPS and time how long it takes for the computer to shut down. Kind of crude but at least you will know.

I am on my third UPS since 2009. The first UPS failed under warranty so I received a free replacement. I think I had some signs of problem but did not know for sure until one day its alarms went off causing it to fail to start. I only remember replacing one UPS battery during that time. I try to run self tests once in a while so I will know when there is a problem. That is how I knew to replace the battery. I know they recommend replacing the battery every so many years but I just wait until the self-test says when its time. Most UPS batteries are lead acid. They do take a long time to charge.

So it looks like it didn't work properly. Here are some events I found. The first one under Application is what occurs every time I boot the computer and I'm pretty sure it's the regular check the UPS does itself at starup.

But then there are two events under System that seem to indicate a hard shutdown. The only strange thing is that it shows the unexpected shutdown at 6:49.02 when that was when I first booted the computer and it ran fine after that until the power went off at 7:15 a.m.

Thanks. I was thinking of trying that too.

As you can see from the messages from the Event view I posted above it looks like it's not working properly but I wonder why it shows that it passed when I run a self-test.

Karen:

I've been using APC Backup-UPS battery backup units for several years.
The BE425M and BE600M1 models are what I currently use.

Once it's no longer receiving electrical power and is running only on its battery, it should beep once about every 30 seconds.
Once its battery gets very low, it should keep beeping continually.

If you want to determine how much burn time the battery has left, make sure to turn off your computer BEFORE it's completely drained.
Do NOT allow the battery to completely drain and shut down your computer.

Yes, it was doing that at first.

I thought so but I had turned that off because the beeps are loud and scared my dog as much as thunder and fireworks. I just turned it back on with the stipulation not between the overnight hours and it's not beeping at the moment.

Understood. :)

I've never installed and used the PowerChute software because I've had no need for it, so I won't comment on it.

I'm currently on my third set of battery-backup units.
When the battery in each unit ran out of juice after about 5 years, I replaced each unit instead of replacing its battery.
It costs a little more, but I prefer having a brand new and more modern unit, and they're also lighter in weight.

It's good to install the software because it shuts down the computer properly if there's a power failure and you're not home. At least it's supposed to. :)

I always prefer to buy a new unit as well since it doesn't cost much more than the battery alone.

The only time any of my computers are on and running is when I'm using them. (y)

If you use PowerChute the battery should never run down completely unless you configure it to. The options are:
Option 1: Preserve battery power
Shuts down computer when it has been on battery power for [5] minutes.

Option 2: Keep computer on as long as possible
Shuts down computer when [5] minutes left on battery.

Well I got my answer. The power flicked off for a couple of seconds and the computer went off completely and the UPS made a long continuous noise (not beeps). So I guess I'd better get a new one pronto!

It did that and still passed the selftest in Powerchute? I am surprised by that.
