My UPS is an Ellipse Eco made by Eaton. Every day without fail it starts a series of beeps, that lasts about 10 seconds, at 12:58 P.M. my time. I am thinking that it has somehow been set to go off at 1:00 but its internal clock has lost two minutes. Then again, it might be programmed for a different time zone in which my 1 pm is 5 pm… or whatever. The thing is it is acting like some sort of alarm clock. I was wondering if perhaps it suffers a loss of voltage input at this exact time every day, but I hooked up a multi-meter to the mains and there was no drop in voltage at all as the “alarm” went off. The thing is, I have no idea how to program or deprogram this “feature” of the UPS. I do have the proprietary Eaton software which, when hooked up to USB, just gives electric data, no place to input data. It’s beginning to have a kind of Groundhog Day effect… Anybody have an idea? ---

Have you contacted the manufacturer and asked them? It sounds like a feature without an obvious purpose. You might be able to download an operator’s manual from the company’s website which should tell you something. ---

Does the UPS beep at that time when unhooked from the computer? It might be running some kind of self test according to some schedule. It might be being tested by the software you mentioned. ---

What is the exact model? There are multiple Ellipse Eco devices. ---

It’s the 800 (and it was happening before I installed the software) ---

How long have you had the UPS? My off-the-cuff guess is that it is checking the internal battery and the beeping is just letting you know that the internal battery needs replacing. Try unplugging it and running your computer off the UPS for about 10 minutes and see what happens. My guess is that it won’t last 2 minutes. ---

I have a completely different brand but it beeps at the same time every day when it performs a self test. When the battery is actually bad it keeps beeping. (Just happened last week in fact and I had to replace the batteries for the second time in 12 years). ---

Try unplugging it and running your computer off the UPS for about 10 minutes and see what happens. My guess is that it won’t last 2 minutes. Bought it 2nd hand about 1 year ago… It will not last two minutes, correct. ---

(Just happened last week in fact and I had to replace the batteries for the second time in 12 years). A self-test… never heard of that before.
