有效的电源管理可以帮助设备降低发热并且省电，在笔记本电脑上这点体现的更加明显，因为它还可以延长笔记本电池的使用寿命，让你免除设备风扇的操作和键盘本身发热带来的不适
电源管理软件
Manjaro有多款电源管理软件可供选择，以下介绍几款流行的软件。
TLP
TLP是自动化电源管理的最常用方案
安装 TLP
TLP可以直接从Manjaro的存储库中获得，也可以使用其他包管理器或者终端命令方式安装
pamac install tlp
Now that it is installed, you need to start and enable the service. This can be accomplished with the command:
systemctl enable tlp --now
Configuring TLP
TLP can manually configured by editing the file /etc/default/tlp as described in The Official Documentation.
A simpler way to configure TLP is via the GUI tool TLPUI
To install TLPUI install the package tlpui using your favorite package manager or with the command
pamac install tlpui
Laptop Mode Tools
An Alternative to TLP for laptops is Laptop Mode Tools(LMT).
Installing LMT
To install laptop-mode-tools, enter the following command into your terminal:
pamac install laptop-mode-tools
Once installed, to enable LMT to start automatically every time you boot your computer, enter the following into your terminal:
sudo systemctl enable --now laptop-mode.service
LMT automatically configures some settings for you in order to optimize your laptop's battery life.
LMT Configuration
For configuration, the file to edit is /etc/laptop-mode/laptop-mode.conf}
The individual kernel modules can be configured from the configuration files present in /etc/laptop-mode/conf.d/
PowerTOP
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.
Installing PowerTop
It can be installed as
pamac install powertop
Generating Reports
You can generate a report using powertop with the command:
sudo powertop --html
This will create the file powertop.html in the current directory. You can open this file in any web browser.
If you are using TLP for power management you may notice some differences in the recommendations between the tools. The article Comparing TLP with PowerTop reporting describes some of the reasons for these differences.
Automated Tuning with PowerTop
The command sudo powertop --auto-tune" will allow PowerTop to automatically tune power management based on it's recommendations.
From a practical perspective, the best way to use PowerTops auto-tuning is with a systemd service.
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
Temperature/Thermal Management
ThermalD
ThermalD, the Linux Thermal Daemon can be used to automatically handle CPU frequency scaling according to system load.
To install it, install thermald in your favorite package manager or use the command:
pamac install thermald
After installing it needs to be configured to automatically start at boot in order to work:
sudo systemctl enable --now thermald
