A few days ago my APC Smart-UPS 1500 starting emitting a fairly annoying, high-pitched screech. I thought I had some logs on screen or dmesg on my server that was saying something about full storage or unable to contact the UPS, but I restarted everything.
I'm running NUT on a rPi, and everything seems normal. When I ask for status, I don't see anything out of range. The UPS self-tests OK when using the front panel button, and has no lights on it indicating battery, etc. I shut everything down, turned off and unplugged the UPS and it still makes the noise (because of the batteries I assume).
It either has to be an alarm, or a piece of equipment inside the unit is making the noise. Has anyone had this happen before?
The unit is one I bought off eBay used, and put new batteries into it. I'm guessing the next step is I have to take the batteries out, but I've just been avoiding it--mostly because I have been doing a lot of photography lately and wanted to make sure the server backups run (such as they are).
