[Guide] Native Power Management for Laptops

I implemented the "Experimental technique: XCPM only" technique, but I am unsure if it is actually working... My battery life is pretty bad and heat / fan speed seem to be worse than linux/windows. I'm using a haswell chip so i figured i'd try it before going the more traditional route...

I tried to follow the instructions on how to test, but it just sort of ends at, run a few benchmarks and look at the AppleIntelInfo.kext results. Problem is, I don't really know what to actually look for...

I've included some files and kextstat outputs... if anyone can give me any advice that would be great.

Code: 
➜  Downloads kextstat|grep -y acpiplat

AppleLPC is not loaded. See ACPI patching guide:

Sorry, I guess the outputs could be different than before the patch. here is the new package of files you've requested.

I included the correct DSDT in my previous post and forgot to update it in the zip. Sorry, and thanks again for taking the time.
