The disabled turbo doesn't work on my Dell XPS 9300, 1065g7, tested on fedora 36 KDE. I'm thus also reaching 100C on cpu while stress test instantly.

Edit: It just resets after reboot, I'll fix this myself with cron or something

Why don't you mention the thermald daemon? It is great for temperature control.

[NebulLLA]

Good video but Chris.... Isnt it possible in Linux to control battery thresholds Fedora??? My Asus Win10 I use Asus battery Health and set to charge arround 60% for more healthy battery when plugged in all day?

Can someone show or write what to do? Tried linux in the past many times but my privacy concerns for windows now and the furture are now so big I´m switching to Linux for good.

I missed it! lol, but definitely will talk about it in the future.

I'll see if I can't find a project that does this, my laptop has a bios setting called adaptive battery that discharges it to 50% when plugged in and charges it up after a period of time.

Thanks..... I will look to see if I got these settings in BOIS as well

No rush and take you time. If you find anything you could make a new video for Youtube for more views and it will help many people as well but you decide ofc

So I have been playing around with auto-cpufreq and its very simple to setup and use. https://github.com/AdnanHodzic/auto-cpufreq

I'm getting this error when I try to turn off cores... and I'm running with sudo, so not sure what the probem is... any suggestions?

bash: /sys/devices/system/cpu/cpu2/online: Permission denied

This typically just needs to be run again. Sometimes I get this and re-running it does the trick.

[5p4r74cu5]

I tried again a number of times and it only worked when I switched to su with the sudo su command...

According to man nproc, just nproc prints the number of processing units available to the current process, which may be less than the number of online processors. That behavior may lead to leaving more active processors than expected.

Also, each pass of the for loop used for disabling processors, nproc will print less active CPUs.

An alternative may be to use nproc --all instead.

how about tlp in my opinion it's a very good program to extend battery life and the default settings are pretty well optimized to extend battery life and with tlp ui it's also quite user friendly

Yeah I just discovered that, it looks promising.

I also found this, but haven't tried it yet: https://github.com/pop-os/system76-power

A question on a different line. In windows laptops after disabling GPU(Ex. Nvidia MX150) in device manager, will it still draw little power ? If so can we stop it?

[ChrisTitusTech]

Windows has no way to officially shut off the nvidia card... hell in Linux it pretty much requires a reboot. So, I prefer the windows method, but it does suck an extra 5W or so in standby mode.

You can do it in linux. I'd recommend switching to linux, I switched over from Windows about 6 months ago, and it was totally worth it.

How to revert back changes like Setting Min/Max Power to default and turn on all cpu cores to default

[BurhanBudak]

What Im missing is disabling turbo boost. The setting is gone in the Legacy Bios(I have UEFI) and the power management. BUt thx Chris, with new thermal paste the laptop isnt goin nuts but the CPU still goes above 2.4Ghz.

[cranky-pythonista]

I recently watched your video on auto-cpufreq and started using it and removed tlp. Now I saw this. Please which suggest which is better, cpufreq vs cpupower? I dont do gaming. Mostly casual tasks and maybe 4k movies on weekends. I'm on laptop btw.

Check BAT out. It's a battery charge threshold command line tool. Supposed to replace the Windows ASUS utility and works by setting a value of either 60% or 80%

UPDATE

Fedora is now installed as my main system (tried linux severial times in the past) but I'm a real noob. In my search for more tweaks and exstention to Fedora I found Battery Health Charging extention.

It works perfect...

Just saw your answer. Haven't tried it yet but will do that.

Thanks!

[sachinchaudhary1808]

so to limit charge to only 60 percent there is wiget tool in debian 12 with kde plasma it has graphical interface to do that @NebuLLA

My processor is 13500HX i just want 2 of the efficiency cores for when i use my laptop unplugged but the core0 is a performance core, cant shut that down any workaround?

I would say just use something like powerprofilectl don't go disabling things that will be always a hadech
