TLP：一个可以延长 Linux 笔记本电池寿命的高级电源管理工具 | Linux 中国
笔记本电池是针对 Windows 操作系统进行了高度优化的，当我在笔记本电脑中使用 Windows 操作系统时，我已经意识到这一点，但对于 Linux 来说却不一样。
多年来，Linux 在电池优化方面取得了很大进步，但我们仍然需要做一些必要的事情来改善 Linux 中笔记本电脑的电池寿命。
当我考虑延长电池寿命时，我没有多少选择，但我觉得 TLP 对我来说是一个更好的解决方案，所以我会继续使用它。
在本教程中，我们将详细讨论 TLP 以延长电池寿命。
我们之前在我们的网站上写过三篇关于 Linux 笔记本电池节电工具 的文章：PowerTOP 和 电池充电状态。
TLP
TLP 是一款自由开源的高级电源管理工具，可在不进行任何配置更改的情况下延长电池寿命。
由于它的默认配置已针对电池寿命进行了优化，因此你可能只需要安装，然后就忘记它吧。
此外，它可以高度定制化，以满足你的特定要求。TLP 是一个具有自动后台任务的纯命令行工具。它不包含GUI。
TLP 适用于各种品牌的笔记本电脑。设置电池充电阈值仅适用于 IBM/Lenovo ThinkPad。
所有 TLP 设置都存储在 /etc/default/tlp 中。其默认配置提供了开箱即用的优化的节能设置。
以下 TLP 设置可用于自定义，如果需要，你可以相应地进行必要的更改。

如何在 Linux 上安装 TLP
TLP 包在大多数发行版官方存储库中都可用，因此，使用发行版的 包管理器 来安装它。
对于 Fedora 系统，使用 DNF 命令 安装 TLP。
-
$ sudo dnf install tlp tlp-rdw
ThinkPad 需要一些附加软件包。
-
$ sudo dnf install https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm
-
$ sudo dnf install http://repo.linrunner.de/fedora/tlp/repos/releases/tlp-release.fc$(rpm -E %fedora).noarch.rpm
-
$ sudo dnf install akmod-tp_smapi akmod-acpi_call kernel-devel
安装 smartmontool 以显示 tlp-stat 中 S.M.A.R.T. 数据。
-
$ sudo dnf install smartmontools
对于 Debian/Ubuntu 系统，使用 APT-GET 命令 或 APT 命令 安装 TLP。
-
$ sudo apt install tlp tlp-rdw
ThinkPad 需要一些附加软件包。
-
$ sudo apt-get install tp-smapi-dkms acpi-call-dkms
安装 smartmontool 以显示 tlp-stat 中 S.M.A.R.T. 数据。
-
$ sudo apt-get install smartmontools
当基于 Ubuntu 的系统的官方软件包过时时，请使用以下 PPA 存储库，该存储库提供最新版本。运行以下命令以使用 PPA 安装 TLP。
-
$ sudo apt-get install tlp tlp-rdw
对于基于 Arch Linux 的系统，使用 Pacman 命令 安装 TLP。
-
$ sudo pacman -S tlp tlp-rdw
ThinkPad 需要一些附加软件包。
-
$ pacman -S tp_smapi acpi_call
安装 smartmontool 以显示 tlp-stat 中 S.M.A.R.T. 数据。
-
$ sudo pacman -S smartmontools
对于基于 Arch Linux 的系统，在启动时启用 TLP 和 TLP-Sleep 服务。
-
$ sudo systemctl enable tlp.service
-
$ sudo systemctl enable tlp-sleep.service
对于基于 Arch Linux 的系统，你还应该屏蔽以下服务以避免冲突，并确保 TLP 的无线电设备切换选项的正确操作。
-
$ sudo systemctl mask systemd-rfkill.service
-
$ sudo systemctl mask systemd-rfkill.socket
对于 RHEL/CentOS 系统，使用 YUM 命令 安装 TLP。
-
$ sudo yum install tlp tlp-rdw
安装 smartmontool 以显示 tlp-stat 中 S.M.A.R.T. 数据。
-
$ sudo yum install smartmontools
对于 openSUSE Leap 系统，使用 Zypper 命令 安装 TLP。
-
$ sudo zypper install TLP
安装 smartmontool 以显示 tlp-stat 中 S.M.A.R.T. 数据。
-
$ sudo zypper install smartmontools
成功安装 TLP 后，使用以下命令启动服务。
-
$ systemctl start tlp.service
