Hi, I have high Sierra installed and working pretty well on my HP Spectre x360. Only issue is that at idle, intel power gadget reports 1.8-1.9W of power usage, versus 0.5 W when idle on Windows. Is there any way I can track down what is drawling this much power from my machine? Problem reporting files attached.

Fixed. Issue is still showing. Any debugging tools I could use to track this down? Could output of AppleIntelInfo be helpful?

Your kextcache output proves kexts are not installed correctly.
All kexts you need must be installed to the system volume.
Read post #2 of the Clover guide for details:

Of course you should have checked your CPU PM with AppleIntelInfo.kext.
See guide:

And your NVMe is likely running without power management. No known solution other than replacing it with a SATA SSD.
 
Looks like it was the NVMe, is there any progress or beta solutions on enabling power management for NVMe drives? I understand that there's nothing finished at the moment but it seems that with newer generation laptops shipping with these drives looking into enabling power management would be useful

None that I know of.
But of course, I'm not using any NVMe for macOS, so I'm not actively searching for any solution to NVMe PM.

Ok, thanks for the advice
 
Does anyone know how to check if third party NVMe drives are getting proper power management? I'm getting horrible battery life with mid-2014 15" mbp using 960 evo 1tb

NVMe PM is known to be not working with non-Apple NVMe devices.
 
Do you think this is something that possible at all or we're just **** out of luck and just need to buy drives that actually perform at lower voltage? Intel 760p and maybe the new 660p QLC drives?
