Battery 0: Discharging, 87%, 01:57:08 remaining
That is all the output I get. Is there a file that is related to
discharge rate some place I can not find? Is this rate built into
the kernel? From what I read this is built in to the kernel but I am
not sure I am grasping that. Am I chasing something that is moot to
overall performance and stability of the laptop? Can I give any
other info I am not thinking of sharing? Is this question that bad I
get the silence? ;)
well, back when I was using a laptop I used /proc/acpi/battery/BAT*/* where
a state file gave information in mAh about the full state and the present
state in which it is discharging. crafting a progressive algorithm that
dynamically averages battery usage and calculates a remaining time from it
shouldn't be that hard.
I'm not really sure where the mechanism that is trying to calculate these
things for you is coming from, and myself would try to shut it down / see
myself to make things cope with strange data. How correct is the estimate you
get, anyway?
On another notice, does the error make your cpu go crazy or something else
imminent like this? Because otherwise I wouldn't worry too much about it.
cheers!

/proc ACPI entries have been deprecated. All files are now located
in /sys/class/power_supply. The correctness of numbers in there depends on your BIOS and can be completely nonexistent...
I do know this laptop has a buggy DSDT but I have never had luck in
trying to get the errors fixed. I can never find things online in
relation to the errors it produces, best I have ever done is clear 2 of
the 200 something errors when trying to recompile it :P
I guess that must be it though the BIOS not playing nice, just weird it
only shows on the Arch kernel. Maybe I need to finally figure out how to
do my DSDT.
