Windows 10: Warning: battery is low; plug the computer in.

My Windows 10 desktop PC today 7/26/18 decided to display a warning continuously that the battery is low and to plug the computer in. I shut it down and changed the plug from UPS to a power bar which my printers which are on are plugged into. Still get the warning message. The battery icon in the system tray shows 6%. It always used to say 100%. I went to Cortana and typed troubleshoot, enter and followed the instruction to troubleshoot hardware. and devices Nothing was found.

Desktop PC warning "Low Battery - Plug Computer In"

My desktop PC today decided to warn me several times that the battery is low and to plug the computer in. It is plugged in or it wouldn't be running. The battery icon in the system tray shows 100%. My PC is plugged into a UPS but the UPS power display
is the same as it normally is. I've jiggled all the cable connections. Is this a bug or is something really wrong?

 

Low battery fails to give warning before putting computer to sleep

When my laptop's battery becomes as low as 10% it has always warned me and given me an opportunity to plug the computer in. But since it updated Windows to Windows 10 Version 1709, the computer goes to sleep without warning even when the battery still is
13% charged. Power options specify low-battery notification to be On. How can I get a warning and an opportunity to plug in?
