#tlp — Public Fediverse posts

Just tested TLP on a ThinkCentre M920q (i5-8500T, 35W TDP) running Proxmox: idle power dropped from 18W to 12W with TLP bat mode + runtime PM on NVMe + intel_powersave governor. That is a 33% reduction. The settings that matter most:

1. CPU_SCALING_GOVERNOR_ON_AC=performance (when plugged in)
2. CPU_SCALING_GOVERNOR_ON_BAT=powersave
3. RUNTIME_PM_ON_BAT=auto (PCIe power management)
4. DISK_APM_LEVEL_ON_BAT=128 (HDD spin-down)
5. WiFi power_save on (offload off for latency-sensitive apps)

Combined with C6 sleep state enabled in BIOS, the box idles at 11-13W. That is barely more than a Raspberry Pi 5 with 3x the compute. SFF/NUC + TLP is the sweet spot for 24/7 homelab.

I'd love to hear your opinions on a possible change to the #TLP #Linux #powersaving tool's configuration.

I just released version 1.10.2 of the #TLP #Linux #powersaving tool. It provides a bug fix that restores the ability to set the charge threshold on ASUS laptops. This feature was broken by a change in kernel 7.1.

@mausmalone #tlp does not "stop working" suddenly, it was just the charge thresholds. You must have done something beforehand to cause tp-smapi-dkms to be uninstalled.

I just released version 1.10.1 of the #TLP #Linux #powersaving tool. It fixes a charge threshold issue on Lenovo laptops (non-ThinkPad and ThinkBooks) and the start of tlp.service on Fedora.

Following a successful beta phase, version 1.10.0 of the #TLP #Linux #powersaving tool has been completed and published today.

You can now choose the profile to use for automatic switching. For example, you may set it to balanced on AC and power-saving on battery power.

Support for power profiles and frequency limits on Intel Xe/Arc GPUs has been added, charge thresholds work with newer kernels and additional hardware.

I have just released version 1.10.0-beta.2 of the #TLP #Linux #powersaving tool.

A number of changes and fixes have accumulated since the first beta. Please take the opportunity to participate in the beta test. I'm looking forward to your results!

Currently, there's no viable way for #Framework laptops to enable the standard sysfs attributes charge_control_start_threshold and charge_control_end_threshold. The out-of-tree framework_laptop module is abandoned, and recent changes to Framework's EC firmware break the cros_charge-control module. #TLP is thus prevented from setting charge thresholds. Let’s hope @frameworkcomputer devs are working on it.

Learn how to extend your Linux laptop's battery lifespan by setting charge thresholds with TLP in Linux. Step-by-step config for all major Laptop brands.

Step-by-Step Guide here: https://ostechnix.com/linux-battery-charge-thresholds-tlp/

#tlp #LaptopBattery #ChargeThreshold #Linuxtips #Linuxhowto #CLI

I would like to hear your opinion on whether I should establish a new #TLP config default:

RESTORE_THRESHOLDS_ON_BAT=1

This would mean that the charge thresholds are reset to their configured values every time the power supply is disconnected. For example, if you previously removed them using tlp fullcharge in order to fully charge the battery for longer mobile operation.

Would this be useful for your use cases? Currently, you have to configure this explicitly.

Il semble que la coexistence entre #tlp et #power-profiles-daemon soit problématique (je n'ai pas beaucoup de détails). Il faut donc arbitrer et le choix majoritaire est en faveur de #tlp (parmi les utilisateurs de #Thinkpad)

@cracrayol

Merci. Pour les #Thinkpad soyez attentifs, une fois de plus cette MàJ m'a tout simplement désinstallé #tlp => sudo apt install tlp

Version 1.9.1 of the #TLP #Linux #powersaving tool was released. It consists mainly of security fixes for #tlp-pd. For details, please refer to the publication by the #openSUSE Security Team.

#TLP #powerprofiles

I'd like to hear your opinion on #TLP auto-switching.

Since release 1.9, #TLP has three #powerprofiles: performance (automatically on AC power), balanced (automatically on battery power), and power-saver (only manually by the user).

Should there be an adjustable preference that allows for something other than the fixed assignment to the power source? What are your use cases?

I have just released version 1.9.0 of the #TLP #Linux #powersaving tool.

Enjoy the brand new #tlp-pd (TLP Profiles Daemon) for easy profile switching with a mouse click!

tlp-pd replaces #power-profiles-daemon by implementing the same D-Bus API that major Linux desktop environments like GNOME, KDE and Cinnamon already use.

https://github.com/linrunner/TLP/releases/tag/1.9.0

#TLP 1.9.0-beta.1 story part 3:

Configuring TLP_AUTO_SWITCH=0 together with TLP_DEFAULT_MODE=BAL: the system comes up with the balanced profile and requires manual switching from there on.

#TLP 1.9.0-beta.1 story part 2:

How do you prefer profile shifting, automatic or manual? As before, you can let TLP do the work.

Configuring TLP_AUTO_SWITCH=2 (the default) means that TLP automatically switches to performance profile every time the charger is connected, and to balanced when it is disconnected. If manually switched to power-saver, this is retained when the power source changes.

I have just released version 1.9.0-beta.1 of the #TLP #Linux #powersaving tool.

The key innovation in this release is the new Profiles Daemon. #tlp-pd enables you to conveniently switch between performance (AC), balanced (BAT) and power-saving (SAV) settings profiles from your Linux desktop environment and replaces #power-profiles-daemon.

Please take part in the beta test. I look forward to seeing your results.

Sait-on pourquoi la màj #LinuxMint 22.1 vers 22.2 désinstalle l'indispensable #tlp ? https://doc.ubuntu-fr.org/tlp

(Indispensable pour les possesseurs d'un Thinkpad, entendons-nous)

For Linux (Ubuntu) I find 2 utilities to do battery management on laptops.
laptop-mode-tools and TLP.
Does anyone know if those are 2 means to the same end, or is there a difference?
