Hi!
I installed win 11 when it came out, but in the last few days i noticed that there is a small battery icon by the clock, like on a laptop. I have a desktop pc, hooked up to an UPS and connected to it via USB (Cyberpower CP1300EPFCLCD). It always displayed that im connected to the grid and battery is always full, so i thought that its just a bug, but today we had a short blackout, the UPS kicked in and the small icon in win11 switched from "connected to the grid" to "battery power: 100% remaining". It stayed on 100% the whole time, even after 10 minutes, so i dont think it works properly, but it definetly detected correctly the change in power supply.
I didnt find anything on it on official sites and never had anything similiar on win10. Can somebody confirm that it will be a new feature when its bug free? Or just the Cyberpower software messed up the win11 energy management?
Hi. Yes, this is something that is supported natively in Windows (and has been for a very long time).
I also couldn't find any official Microsoft documentation on it, but this has some details - https://www.apc.com/us/en/faqs/FA164514/
The driver is hidbatt.sys.
Now it's also possible that Cyberpower installed their own software/driver that integrates with Windows - looking in device manager (mentioned in the link above) to see the name of the driver being used would let you know which it is.

Yes the Cyberpower software does that. It can also be set to automatically shut your PC down after a certain percentage remaining. I would test it by running down the battery further and seeing what happens, you may need to contact Cyberpower support.
