Save Some Battery On Our Linux Machines With TLP
|
||||
======
|
||||
|
||||
|
||||
I have always found battery life with Linux to be relatively lesser than windows. Nevertheless, this is [Linux][1] and we always have something up our sleeves.
|
||||
|
||||
Now talking about this small utility called TLP, that can actually save some juice on your device.
|
||||
|
||||
|
||||
|
||||
**TLP - Linux Advanced Power Management** is a small command line utility that can genuinely help extend battery life by performing several tweaks on your Linux system.
|
||||
|
||||
```
|
||||
sudo apt install tlp
|
||||
```
|
||||
|
||||
[][2]
|
||||
|
||||
For other distributions, you can read the instructions from the [official website][3] .
|
||||
|
||||
|
||||
|
||||
After installation is complete, you will have to run the following command to start tlp for the first time only. TLP will automatically start the next time you boot your system.
|
||||
|
||||
[][4]
|
||||
|
||||
Now TLP has started and it has already made the default configurations needed to save battery. We will now see the configurations file. It is located in **/etc/default/tlp**. We need to edit this file to change various configurations.
|
||||
|
||||
There are many options in this file and to enable an option just remove the leading **#** character from that line. There will be instructions about each option and the values that you can allot to it. Some of the things that you will be able to do are -
|
||||
|
||||
* Autosuspend USB devices
|
||||
|
||||
* Define wireless devices to enable/disable at startup
|
||||
|
||||
* Spin down hard drives
|
||||
|
||||
* Switch off wireless devices
|
||||
|
||||
* Set CPU for performance or power savings
|
||||
|
||||
### Conclusion
|
||||
|
||||
TLP is an amazing utility that can help save battery life on Linux systems. I have personally found at least 30-40% of extended battery life when using TLP.

TLP 帮助我们的 Linux 机器节能省电
|
||||
======
|
||||
|
||||
|
||||
我发现 Linux 下电池的寿命普遍要比 windows 下要短。尽管如此，这可是 [Linux][1]，我们总会有有办法的。
|
||||
|
||||
现在来讲一下这个名叫 TLP 的小工具，它能帮你的设备省点电。
|
||||
|
||||
**TLP - Linux 高级电源管理** 是一个小巧的命令行工具，它通过对 Linux 系统执行一些调整来真正帮助延长电池的寿命。
|
||||
|
||||
```
|
||||
sudo apt install tlp
|
||||
```
|
||||
|
||||
[][2]
|
||||
|
||||
对于其他的发行版，你可以阅读[官方网站 ][3] 上的指南。
|
||||
|
||||
安装完成之后，你只有在第一次的时候需要运行下面命令来启动 tlp。TLP 会在下次启动系统时自动运行。
|
||||
|
||||
[][4]
|
||||
|
||||
现在 TLP 已经被启动起来了，而且已经设置好了节省电池所需要的默认配置。我们可以查看该配置文件。文件路径为 **/etc/default/tlp**。我们需要编辑该文件来修改各项配置。
|
||||
|
||||
配置文件中有很多选项，要启用某个选项的话之胥敖删除行首的 **#** 就行了。每个选项能够赋予什么值都有说明。下面是你可能会用到的选项 -
|
||||
|
||||
* 自动休眠 USB 设备
|
||||
|
||||
* 设定启动时启用/禁用无线设备
|
||||
|
||||
* 降低硬盘转速
|
||||
|
||||
* 关闭无线设备
|
||||
|
||||
* 设置 CPU 以性能优先还是节能优先
|
||||
|
||||
### 结论
|
||||
|
||||
TLP 是一个超棒的工具，可以延长 Linux 系统中电池的寿命。我个人的经验是使用 TLP 能延长至少 30-40% 的电池寿命。
