My battery status indicator and the Power settings don't show the current (correct) battery status. When I start my pc with the battery charging, even if I unplug from AC, it keeps showing that the battery is charging - when it is obviously wrong, and moreover the percentage doesn't decrease. And this also happens on the opposite: if I start the pc and the battery isn't charging, no matter how many times I plug and unplug, it will never indicate it is actually charging, even if I can see the percentage increasing over time. I already tried re-installing the indicator but it didn't solve anything., and the bar in the Power settings has the same behaviour.
How can I fix it?
