From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I've installed TLP on my Lenovo ThinkBook laptop and was wondering if there are additional steps I can take to extend the battery life when using the laptop unplugged.

Could you please share more tips and tricks for maximizing battery life on Linux laptops?

I'm moderately capable but a bit of a noob and oddly enough have a t480 with Debian and been trying to get hibernate to work. Did you figure this out yourself or was there a guide you followed that you might be able to point me to?

I've outlined the steps you have to take in my 1st post. basically, add swap, add resume to loader, rebuild initramfs, selinux policies, trick systemd to ignore absent swap (it gets activated on suspend) and that's pretty much it. then once systemctl hibernate works, switch suspend with suspend-then-resume system wide; optional, if you don't want that (spoiler: you do want that).

first made it work on fedora (linked post in my previous reply) and then recreated it in Arch with copious help from the wiki; not much different except mkinitcpio instead of dracut. then redid it in debian first with GRUB and then replaced it with systemd-boot.

maybe do a step-by-step writeup one of these days if I find the time.
