For the past week I have been getting Low Battery warnings on my desktop machine. Machine is plugged in to an APC Back-UPS ES 750. There are no error lights on the APC and the machine is otherwise working fine. Do I have a bad power supply? How can I find out?

A Low battery alarm refers to the CMOS battery on the motherboard itself. This battery is responsible for keeping all your custom BIOS settings and the time on the computer when it's turned off. This battery looks similiar to a watch battery. This is the battery that needs to be replaced.

Or am I misinterpreting the error and you are getting this inside windows.... not when first booting up?

I get it in windows and this morning before I logged on, none of these times has been after a restart/shut down though (at least not yet). Could it still be the CMOS batter?

Probably not, it's an unusual message for sure in a Desktop system. I would narrow it down a bit. Plug the computer directly in the wall and see if you still get the message if not it could be a problem with the APC

I replaced the battery in the APC and it seems to be functioning correctly now.

Thanks much for your help!
