[Guide] Native Power Management for Laptops

Does anyone know ?
Intel HD 4400 should stay at 200 , even when playing video ? The only time I see max speed is on benchmark.

Is it possible , like on windows , to have cpu-gpu constantly at max frequency when on power and enable speed step only when on battery ?

Not that I know of.
And that would causes excessive heat anyway... no reason to do it either.
 
Made some changes to dsdt and config.plist.

Can you check ?

Hi @RehabMan, I have a question? in THe CoffeLake using one of your config.plist the native power management is enabled by default because of the CLover>ACPI>SSDT>GENERATE>PLUGINTYPE>true? but I have very high clock speeds even when idle. WHat should I do? thank you for your answer
