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 need some help with linux energy management and hibernation (lemmy.ml)

Hi there!

I need some help with my framework laptop and fedora. I want to switch to linux more permanently, but fedora does not enter hibernation properly when closing the lid. I dont care 10-20sec of wakeup time when opening it again. (even windows is more efficient?!) The relatively bad performance on battery life is OK for me, I already installed TLP instead of the default power management. But when closing the lid, the battery drains about 80% over night (10h?) which seems to be more than what other people reported.

I could not find a guide on this, which i understood (still a massive noob to afraid to mess up my carefully crafted linux partition :D).

If you have any advice I appreciate it! Thanks a lot! :)

See: https://wiki.archlinux.org/title/Power_management/Suspend_and_hibernate

You're probably missing a swap position or file. Modern Linux distro don't really support hibernate out of the box.

Also depending on ports you can have worse sleeping power draw. All USB C will give you the best battery life.

I have read this about the expansion cards and only use 2c and 2A. A bit stupid considering you can hack the hdmi port into suspending on its own.. Did not expect this from fw.

I will check out the link, thanks!

IIRC framework is working on addressing the expansion card issue via firmware/BIOS but it's been a while since I've seen any updates.

I generally lose 20-40% battery overnight with USBC and USBA in deep sleep mode. But I have set up hibernate in the past and had it working.

That is almost equivalent to 1h of browsing in Linux! :D \s Other expension cards are drawing about 1W of power, even without use! That's crazy much I think..

[–] PainInTheAES@lemmy.world 2 points 11 months ago (1 children)

Kinda true though. I wish Framework would focus on power usage a bit. As much as I love the concept and laptop the battery life is not one of its strong points. I've done a lot of tuning and squeeze about 6-7 hrs out at ~40% screen brightness.

[–] WbrJr@lemmy.ml 1 points 11 months ago (1 children)

In Linux?! That's quite a bit. With heavy workload?

[–] PainInTheAES@lemmy.world 1 points 11 months ago (1 children)

Yeah, but with a light workload (browsing, some videos, office applications). It lasts longer than Windows where I get like 5 hours.

Yo lol, that's impressive :D
