TLP is a pure command line tool with automated background tasks. It does not contain a GUI. - -TLP runs on every laptop brand. Setting the battery charge thresholds is available for IBM/Lenovo ThinkPads only. - -All TLP settings are stored in `/etc/default/tlp`. The default configuration provides optimized power saving out of the box. - -The following TLP settings is available for customization and you need to make the necessary changes accordingly if you want it. - -### TLP Features - - * Kernel laptop mode and dirty buffer timeouts - * Processor frequency scaling including “turbo boost” / “turbo core” - * Limit max/min P-state to control power dissipation of the CPU - * HWP energy performance hints - * Power aware process scheduler for multi-core/hyper-threading - * Processor performance versus energy savings policy (x86_energy_perf_policy) - * Hard disk advanced power magement level (APM) and spin down timeout (per disk) - * AHCI link power management (ALPM) with device blacklist - * PCIe active state power management (PCIe ASPM) - * Runtime power management for PCI(e) bus devices - * Radeon graphics power management (KMS and DPM) - * Wifi power saving mode - * Power off optical drive in drive bay - * Audio power saving mode - * I/O scheduler (per disk) - * USB autosuspend with device blacklist/whitelist (input devices excluded automatically) - * Enable or disable integrated wifi, bluetooth or wwan devices upon system startup and shutdown - * Restore radio device state on system startup (from previous shutdown). - * Radio device wizard: switch radios upon network connect/disconnect and dock/undock - * Disable Wake On LAN - * Integrated WWAN and bluetooth state is restored after suspend/hibernate - * Untervolting of Intel processors – requires kernel with PHC-Patch - * Battery charge thresholds – ThinkPads only - * Recalibrate battery – ThinkPads only - - - -### How to Install TLP in Linux - -TLP package is available in most of the distributions official repository so, use the distributions **[Package Manager][5]** to install it. - -For **`Fedora`** system, use **[DNF Command][6]** to install TLP. - -``` -$ sudo dnf install tlp tlp-rdw -``` - -ThinkPads require an additional packages. - -``` -$ 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 -``` - -Install smartmontool to display S.M.A.R.T. data in tlp-stat. - -``` -$ sudo dnf install smartmontools -``` - -For **`Debian/Ubuntu`** systems, use **[APT-GET Command][7]** or **[APT Command][8]** to install TLP. - -``` -$ sudo apt install tlp tlp-rdw -``` - -ThinkPads require an additional packages. - -``` -$ sudo apt-get install tp-smapi-dkms acpi-call-dkms -``` - -Install smartmontool to display S.M.A.R.T. data in tlp-stat. - -``` -$ sudo apt-get install smartmontools -``` - -When the official package becomes outdated for Ubuntu based systems then use the following PPA repository which provides an up-to-date version.

+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了三篇关于 Linux [笔记本电池节电工具][1] 的文章：[PowerTOP][2] 和 [电池充电状态][3]。 + +### TLP + +[TLP][4] 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 +*

Debian/Ubuntu 系统，使用 [APT-GET 命令][7] 或 [APT 命令][8] 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][9] 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][10] 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
