2009/11/12 Sam Varshavchik <[email protected]>:Somehow, since a few weeks ago, occasionally gnome power manager loses its mind and starts telling me that my laptop battery's "last full charge" is 946.0 watt-hours of juice. Which makes the battery percentage indicator pretty much meaningless.Have a look at /sys/class/power_supply/BAT*/* when this happens. I would bet money the kernel is lying to us.
If I'm reading this right, the kernel is giving out right data. [r...@lc2440 BAT0]# cat /sys/class/power_supply/BAT0/energy_full 63000000 [r...@lc2440 BAT0]# cat /sys/class/power_supply/BAT0/energy_full_design 60000000 [r...@lc2440 BAT0]# cat /sys/class/power_supply/BAT0/energy_now 59055000This matches up what gnome-power-manager is telling me what my current charge is -- 59 watt-hours left. My full charge is 63 watt-hours, and the full design charge is 60 watt-hours (it's a fairly new battery).
Meanwhile, with all of the above, gnome-power-manager is now showing me the last full charge of 947.4 watt-hours, throwing everything off kilter.
