Notebook suddenly shutting down on battery at 20% charge
Product: EliteBook X360 1030 G2
Operating System: Microsoft Windows 10 (64-bit)
My notebook has started shutting down suddenly, without warning, when on battery. It happens when the charge reaches about 20%. The system instantly shuts down and will not reboot at all unless it's plugged back in. It seems like there's a discrepancy between the real charge level and what Windows is seeing because of a bad cell. I've run the Battery Check diagnostic, and it says the battery is fine, but in the Advanced screen I see the following:
Not sure if I'm reading this properly: it looks to me like Cell 1 is simply not taking a charge at all. Yet the other stats are in normal range. Any clues how to interpret this? Or further diagnostic steps?
