Before you head into this info dump you should know I'm not a professional! I'm just someone who wanted better battery life and a quieter laptop. This info dump will benefits laptop and PC users.

What is core parking

Intel CPUs that are Meteor Lake and below (Anything above Meteor Lake is handled differently afaik.) do not utilize their E and LPE cores like they do on Windows because the CPU scheduler prefers the P cores and will only use E or LPE cores when absolutely needed.

I'm unsure how the scheduler works on Windows but what I do know is Windows will "park" your CPU cores to save on battery. Window does this based of dynamic usage and your power profile and bla bla bla it basically just parks and unparks cores as it sees fit which is fine.

So what is core parking? In a easy to understand way it is a feature that tells the CPU scheduler it cannot use those cores, which allows those cores to sit idle in a sleep state in turn saving battery life.

I have a website now that includes a more dumbed down but straight forward version of this guide that isnt basied towards Arch Linux but considers most distros. https://linuxguidance.net/improve-battery-and-optimize-your-linux-laptop/

Everything I do in this guide is mostly taken from the Arch Wiki, and is for Arch Linux, obviously this can probably be applied to other Linux distributions especially Arch based ones, this guide is for people who want a laptop with similar effciency they had on Windows or MacOS. I hate the excuse of having to compromise on Linux to have good battery or thermals on laptops.

Please think of this guide as more of a starting point, if you're serious about fully optimizing your laptop research your laptop and the hardware inside of it as that can get you even further down the rabbit hole.

This guide assumes you have a relatively modern laptop with at least an SSD from the factory, if you don't, don't worry you can still probably follow this guide perfectly, if you have a 32-b
