[Guide] Native Power Management for Laptops

[RustyIsotope]

I have attached the output from AppleIntelInfo.kext from my laptop with a 6200u. I am not sure how to tell from this info if power management is working properly or not.

I'm having a very weird issue with power management.

I have HWP enabled and working, with injected frequency vectors. I have noticed that my battery life vastly improves if I briefly plug in an AC adapter. I don't have to charge the computer, just have to get it to recognize the AC adapter and battery management will improve after the AC adapter is unplugged

I'm using SSDT-PluginType1 as opposed to the full SSDT from ssdtprgen.sh, and X86PlatformPlugin is loaded.

You should open a separate thread.

CPU pstate x27 is consistent with your CPU specs.
Lower idle pstate could probably be attained by tweaking FrequencyVectors in the associated X86PlatformPlugin plist.

My base CPU and GPU freqs are stuck at much higher base freqs. How can I make them drop below 1.30 GHz and 500 MHz respectively. As per GPU, it's not much, 200 MHz, but for CPU it's almost 3 times the base/low frequency.

If I run Geekbench, test CPU goes up to 2.50GHz (no 2.70GHz for some reason?) and GPU goes upto 850 MHz (no 900 MHz too?). And Temperature went up to 52 C.


From Intel Power Gadget:
Base CPU frequency is always set to 1.30 GHz
Base GPU: 500 MHz.

Should I try using Experimental technique: XCPM only method?

I found it! I reapplied the guide and checked the terminal log and guess what?

What is your suggestion, RehabMan?

Thanks

Read about Pike's freqVectorsEdit.sh script.

I did and decided not to go with it and used SSDT-PluginType1 instead. But kext is not loading now. Should I add SSDT-PluginType1 to clover config's sortedorder?

If you're using SortedOrder and SSDT-PluginType1.aml is omitted, it will not load.

How can I make it to load with dropoem=true (also with sortedorder) then?

You must include all the SSDTs you expect to load in SortedOrder.
Clover will load only those SSDTs listed, in the order listed.
