Battery icon shows 255% even when battery not installed

HP dv-6c63NR Laptop. Recently (not sure when it started), the battery icon in the System Tray show 255% charge when the battery is installed or removed. I've rebooted multiple times and just finished a reset. Nothing changes, still shows 255% charge.

Any suggestions on how to trouble shoot this?

It was okay a week or two ago.

This laptop is in the Insider Fast stream and currently has 1903 18362.1. I could install a non-insider build on my 2nd HDD (I have a 500GB SSD boot and a 500GB HDD 2nd drive) as a test.

As 255% is FF (hex) - all 1's - suggests a certain kind of bug...

If you have a live boot disk, that should prove it's not hardware related.

You could also try a 3rd party battery monitoring program, but if that reads the same buggy info from the OS, might give garbage too.

The battery should last about 3 hours, I still think it's a Windows power managment setting check this link for info
