This seems to be an acpi problem, since acpitool reports the same wrong value.
~$ acpitool -B Battery #1 : present Remaining capacity : unknown, 99.33%, 00:00:00 Design capacity : 5616 mA Last full capacity : 5816 mA Present rate : 2289 mA <----------- WRONG Charging state : Discharging Battery type : Li-ion Model number : 42T4647 Serial number : 2487 So maybe this isn't powertop related.
