Hi there, i just discovered powertop and i love it! However, i'm not getting consistent feedback about ACPI power usage... from looking at it, i guess i first have to wait at least 5 minutes to get it to start working, but it doesnt work.
Well, it does, i've seen it say sometimes i use 0.1 watt (when really really idle) and that i have like 8 hours left of battery, i even tried lowering the laptop backlight at that moment and usage went to 0.0 watt with 14 hours left. I'm pretty sure the estimate is wrong, i never seen my laptop on battery for more than 3-4 hours (i once wrote a script that would echo `date` > somefile every minute or so and the pc was really idle other than that, power was lost after around 4 hours. In any case, i'm sure when the estimate will say i have only a few minutes left, that it will be close to the truth! The problem i'm experiencing is i've seen this estimate a few times only and it stopped showing for unknown reason. It is stuck on "no ACPI power usage estimate available"... However, ACPI does report information about it: # cat /proc/acpi/battery/BAT0/state present: yes capacity state: ok charging state: discharging present rate: unknown remaining capacity: 50 mAh present voltage: 7452 mV # Any help will be greatly appreciated!
