this seems to make sense now, it looks like your battery is dead: > /proc/acpi/battery/BAT0/info:design capacity: 5200 mAh > /proc/acpi/battery/BAT0/info:last full capacity: 100 mAh > /proc/acpi/battery/BAT0/state:remaining capacity: 90 mAh I think powertop filters these obviously wrong numbers and it's likely that the '90 mAh' number doesn't change over time. since powertop makes estimates based on deltas, it can't computate anything from this. Does that battery actually work reasonably long or is it dead? Auke _______________________________________________ Power mailing list [email protected] http://www.bughost.org/mailman/listinfo/power
