    Battery 255% after Windows Update Sept 2022


    My Surface Pro 4 battery suddenly shows a 255% charge after the most recent Windows updates. If I unplug the Surface from the power source, it immediately dies. Any idea how this can be fixed? Thank you.

    Battery icon shows 255% even when battery not installed

    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.

    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.
