current power consumption

[Joerg Sommer <joerg@alea.gnuu.de>]

Hi,

is it possible to get the current power consumtion from
/proc/pmu/battery_0?

$ cat /proc/pmu/battery_0 

flags      : 00000013
charge     : 3789
max_charge : 3930
current    : 195
voltage    : 12650
time rem.  : 2603

I've measured a power consumption of 24 Watt, but I don't know where to
find this in values above. What are the units of the values above? Is
charge and max_charge in Ah (Ampere hours) and voltage in mV? Why current
is 0 if the battery is full? The laptop still consumes power.

Bye, Jörg.

PS: I have a iBook G4
