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.

/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... -- Leonid Isaev GnuPG key ID: 164B5A6D Key fingerprint: C0DF 20D0 C075 C3F1 E1BE 775A A7AE F6CB 164B 5A6D
