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。 TLP 功能 内核笔记本电脑模式和脏缓冲区超时 处理器频率调整，包括 “turbo boost”/“turbo core” 限制最大/最小的 P 状态以控制 CPU 的功耗 HWP 能源性能提示 用于多核/超线程的功率感知进程调度程序 处理器性能与节能策略（x86_energy_perf_policy） 硬盘高级电源管理级别（APM）和降速超时（按磁盘） AHCI 链路电源管理（ALPM）与设备黑名单 PCIe 活动状态电源管理（PCIe ASPM） PCI(e) 总线设备的运行时电源管理 Radeon 图形电源管理（KMS 和 DPM） Wifi 省电模式 关闭驱动器托架中的光盘驱动器 音频省电模式 I/O 调度程序（按磁盘） USB 自动暂停，支持设备黑名单/白名单（输入设备自动排除） 在系统启动和关闭时启用或禁用集成的 wifi、蓝牙或 wwan 设备 在系统启动时恢复无线电设备状态（从之前的关机时的状态） 无线电设备向导：在网络连接/断开和停靠/取消停靠时切换无线电 禁用 LAN 唤醒 挂起/休眠后恢复集成的 WWAN 和蓝牙状态 英特尔处理器的动态电源降低 —— 需要内核和 PHC-Patch 支持 电池充电阈值 —— 仅限 ThinkPad 重新校准电池 —— 仅限 ThinkPad 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 add-apt-repository ppa:linrunner/tlp $ sudo apt-get update $ sudo apt-get install tlp 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 使用方法
