auto-cpufreq is a great find and recommendation! Slowly inching closer to finally setting a weekend aside to set up dual-boot Zorin/Linux. Do note this on the repo’s readme though:
Please note: auto-cpufreq aims to replace TLP and after you install auto-cpufreq it’s recommended to remove TLP. However, if for some reason you still need/want TLP installed and running auto-cpufreq doesn’t conflict and works great in tandem with TLP.
