Well the only other info I can find online, besides trying different 
settings which have had no effect. I have tried numerous 
fixes/workarounds that were posted in regards to people having a similar 
bug but it was in regards to acpi telling them it was discharging at 
zero rate. My output is as follows

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? ;)

Anyways thanks for reading, hope I am not just pumping noise
