Introduction to Power Management
I’ve always been keen on optimizing my laptop’s power consumption, and with the latest Linux kernel and systemd advancements, it’s become a lot easier to manage. In this article, I’ll walk you through my experience with taming my laptop’s power usage using systemd and Linux tools.
Understanding Power Consumption
To get started, you need to know where your laptop is consuming power. I usually start with the powertop tool to analyze power usage. It’s a command-line tool that shows you which components are consuming the most power. You can install it on most Linux distributions, including Arch Linux and Debian. Don’t bother with the GUI tools for this - powertop gives you all the info you need.
