Public bug reported: My laptop is plugged into main power most of the time, but as I'm currently travelling, it's connected a lot more intermittently right now. So I don't know when this problem started. But I noticed my desktop indicator was reporting 9% charge and that the battery was not being charged. Disconnecting and reconnecting the power did not change this. Suspending and resuming did not change this. But after rebooting, the desktop was CORRECTLY showing that the battery was at 100% capacity.
The problem seems to be wrong values being reported in /sys from the kernel: $ cat /sys/class/power_supply/BAT0/charge_{full,full_design,now} 170300000 328720000 65330000 $ The charge_now value is, TTBOMK, correct. But the charge_full value is NOT and appears to change over time? So now my laptop which has been plugged in over night is reported to be at 38% battery.
