Battery icon in notification area bug

On my 18.04 desktop, I have a red battery icon in my notification area. It puts up a message that my battery is in critical condition, and comes up on any screen that I might be using, even over a game screen.

I figured out what to do. I went into Startup and disabled the Power Manager daemon. Rebooted and it is gone.

Click on the "Show more" button. :smiley:

I have marked my answer as ā€œSolvedā€ as you need at least one answer to mark it as such (you donā€™t need to type ā€œSOLVEDā€ in the title-bar of the thread starter now!). :smiley:
