I am seeing something strange with my SP4 as of lately. Maybe someone can make heads or tails of this. I have BatteryBar Pro, and it says I'm connected to A/C, and then shortly after it'll show me the time I have remaining (when already charged at 100%). So I ran a battery report and this is what I saw... In regards to battery bar pro, this is what I'm seeing: It'll cycle between these two... And then actual Battery Bar Pro upon hovering over it shows: and Can anyone tell me if this is hardware related or software related? I have two OEM chargers, and they both show the same thing. So I know it's not the charger itself. Update: Issue is gone, I thought I'd let everyone know what has changed. What I did was uninstall Battery Bar Pro, and then restarted, and reinstalled it again. What I believe happened is that since the last firmware update that MS released, which contained some new drivers for the battery and charging, conflicted with the BBP drivers. So I uninstalled, and reinstalled, and I haven't seen this issue yet.
