TLP – An Advanced Power Management Tool That Improve Battery Life On Linux Laptop
|
||||
======
|
||||
|
||||
Laptop battery is highly optimized for Windows OS, that i had realized when i was using Windows OS in my laptop but it’s not same for Linux.
|
||||
|
||||
Over the years Linux has improved a lot for battery optimization but still we need make some necessary things to improve laptop battery life in Linux.
|
||||
|
||||
When i think about battery life, i got few options for that but i felt TLP is a better solutions for me so, i’m going with it.
|
||||
|
||||
In this tutorial we are going to discuss about TLP in details to improve battery life.
|
||||
|
||||
We had written three articles previously in our site about **[laptop battery saving utilities][1]** for Linux **[PowerTOP][2]** and **[Battery Charging State][3]**.
|
||||
|
||||
### What is TLP?
|
||||
|
||||
[TLP][4] is a free opensource advanced power management tool that improve your battery life without making any configuration change.
|
||||
|
||||
Since it comes with a default configuration already optimized for battery life, so you may just install and forget it.
|
||||
|
||||
Also, it is highly customizable to fulfill your specific requirements. 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

|
||||
$ 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
|
||||
```
|
||||
|
||||

TLP：一个可以延长 Linux 笔记本电池寿命的高级电源管理工具
|
||||
======
|
||||
|
||||
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

||||
|
||||
### 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][5] 来安装它。
|
||||
|
||||
对于 Fedora 系统，使用 [DNF 命令][6] 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][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 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
|
||||
```
|
||||
|
||||

|
||||
|
||||
```
|
||||
$ sudo yum install smartmontools
|
||||
```
|
||||
|
||||
对于 openSUSE Leap 系统，使用 [Zypper 命令][11] 安装 TLP。

|
||||
|
||||
```
|
||||
$ sudo zypper install smartmontools
|
||||
```
|
||||
|
||||
成功安装 TLP 后，使用以下命令启动服务。
|
||||
|
||||
```
|
||||
