Desktop starts showing active laptop battery usage

Window 11 24H2

My HP Desktop computer had just begun showing an active laptop battery including charging, discharging and shutting the computer down. This I believe began with the last 24H2 update. I do have a APS UPS but that never was indicated by the battery icon on. The computer AC plugs into the UPS. Noted also that Windows which is Pro version shows that an optional HP Firmware update is available, but when I tried to install it, it does not. Not sure if that is connected.
Stumped... Thanks for any assistance

It is OS Build 26100.4351. I've have had the computer for years and maybe I've done something incorrectly but it seems that the battery icon was always full and never functioning. Did I inadvertently click some option? Battery usage shows no usage in the past seven days although this morning the icon indicated it was almost out of power and now it has recharged to 100%???

UPS are monitored if you have connected the USB cable from the UPS to the PC. Have you? Simply remove the cable. Look at Settings, Apps, Installed Apps if you find anything relevant and uninstall it.

Thank you for the information!! Yes there is a cable (looks like a phone jack plug to a usb) attached to the computer. I have owned this UPS for decades. I do not keep my computer on when not in use, although the APC UPD ES 550 is continuously plugged in. When I turned the computer on this morning, thee computer indicated that the battery was at 0% and I it stopped. Not paying attention, sorry, I believe I just restarted the computer and it is running and is currently recharging and up to 3%. Window's Battery levels show that for the last 7 days it has had 0% charge which is well before this problem appeared. My screen shuts down and led blinks when I turn the computer off (as always) as well as the external speakers stay powered. It appears to act like a virtual laptop...........? What battery is being monitored??? This is an HP DESKTOP and 3 or so days ago it did not do this. I must be having a brain f*rt or something is unusually going on!
Appreciate the help. Windows shows that no apps have been using any power.... I will not disconnect the USB cable until I get more understanding of my situation.

I did decide to pull the USB cable off and the Battery indicator disappeared, so it is monitoring the UPS battery level????? It has been so long since I have messed with the UPS that I have forgotten about it. Although I haven't been able to reconcile all of my system's symptoms.

Bingo! It was the UPS battery level. I remember once in Windows XP that I had enabled UPS monitoring by curiosity and the computer wouldn't load Windows because no UPS was detected! I had to boot in Safe Mode and disable UPS monitoring. We frequently learn from our mistakes.

Hey, since I am trying not to disconnect the cable permanently, I tried a different BackUp Battery in the UPS. Still seem to be having some of same issues but I should let the new battery charge overnight. Will follow up again if it does or doesn't solve the problem.
Thanx.
