<div lang="en" dir="ltr" class="mw-content-ltr">
Power Saving techniques can be used to minimize the heat produced and conserve energy.  On laptops, this can be especially important as it can significantly extend battery life and excessive heat can be both uncomfortable and loud on portable devices.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=Power Management Software=
[[File:battery.png|left|96px]]
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
There are several options for managing power under Manjaro.  In this article, we will introduce three of the more popular options.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
{{note|In most cases running more than one power management tool at a time can cause conflicts so it is best practice to only use one of the below options}}
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
[http://linrunner.de/en/tlp/tlp.html TLP] is the most commonly used option for automatic power management.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
===Installing TLP===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
TLP is available from the Manjaro repositories, can be installed with your favorite package manager or by using entering the following command into your terminal:
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
pamac install tlp
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Now that it is installed, you need to start and enable the service.  This can be accomplished with the command:
 systemctl enable tlp --now
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
{{note|TLP 1.2.2 and lower need another service as well: tlp-sleep.service}}
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
===Configuring TLP===
[[File:Tlpui.png|left|400px]]
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
TLP can manually configured by editing the file '''/etc/default/tlp''' as described in [http://linrunner.de/en/tlp/docs/tlp-configuration.html The Official Documentation].
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
A simpler way to configure TLP is via the GUI tool [https://github.com/d4nj1/TLPUI TLPUI]
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
To install TLPUI install the package '''tlpui''' using your favorite package manager or with the command
 pamac install tlpui
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
==Laptop Mode Tools==
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
An Alternative to TLP for laptops is [https://github.com/rickysarraf/laptop-mode-tools Laptop Mode Tools(LMT)].
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
===Installing LMT===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
To install {{ic|laptop-mode-tools}}, enter the following command into your terminal:
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
pamac install laptop-mode-tools
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Once installed, to enable LMT to start automatically every time you boot your computer, enter the following into your terminal:
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
sudo systemctl enable --now laptop-mode.service
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
LMT automatically configures some settings for you in order to optimize your laptop's battery life.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
===LMT Configuration===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
For configuration, the file to edit is {{ic|/etc/laptop-mode/laptop-mode.conf}}}
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
The individual kernel modules can be configured from the configuration files present in {{ic|/etc/laptop-mode/conf.d/}}
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
==PowerTOP==
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
PowerTop a diagnostic tool used to identify and report issues with power consumption and management.  It can be used as a reporting tool, an automated power management tool or both.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
===Installing PowerTop===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
It can be installed as
 pamac install powertop
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
===Generating Reports===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
You can generate a report using powertop with the command:
 sudo powertop --html
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
This will create the file {{ic|powertop.html}} in the current directory.  You can open this file in any web browser.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
If you are using TLP for power management you may notice some differences in the recommendations between the tools.  The article [http://linrunner.de/en/tlp/docs/tlp-faq.html#powertop Comparing TLP with PowerTop reporting] describes some of the reasons for these differences.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
===Automated Tuning with PowerTop===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
The command {{ic|sudo powertop --auto-tune"}} will allow PowerTop to automatically tune power management based on it's recommendations.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
From a practical perspective, the best way to use PowerTops auto-tuning is with a systemd service.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
To create, start and enable a systemd service for PowerTop you can use the commands:
 sudo sh -c "echo -e '[Unit]\nDescription=PowerTop\n\n[Service]\nType=oneshot\nRemainAfterExit=true\nExecStart=/usr/bin/powertop --auto-tune\n\n[Install]\nWantedBy=multi-user.target\n' > /etc/systemd/system/powertop.service"
 sudo systemctl enable --now powertop.service
</div>

</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
==ThermalD==
[https://github.com/intel/thermal_daemon ThermalD], the Linux Thermal Daemon can be used to automatically handle CPU frequency scaling according to system load.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
To install it, install {{ic|thermald}} in your favorite package manager or use the command:
 pamac install thermald
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
After installing it needs to be configured to automatically start at boot in order to work:
 sudo systemctl enable --now thermald
</div>
