TLP：一个可以延长Linux笔记本电池寿命的高级电源管理工具

发布时间：2019-05-14 01:12:17 所属栏目：Windows 来源：Magesh Maruthamuthu
导读：副标题#e# 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

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。

  1. $ sudo systemctl mask systemd-rfkill.service
  2. $ sudo systemctl mask systemd-rfkill.socket

对于 RHEL/CentOS 系统，使用 YUM 命令 安装 TLP。

  1. $ sudo yum install tlp tlp-rdw

安装 smartmontool 以显示 tlp-stat 中 S.M.A.R.T. 数据。

  1. $ sudo yum install smartmontools

对于 openSUSE Leap 系统，使用 Zypper 命令 安装 TLP。

  1. $ sudo zypper install TLP

安装 smartmontool 以显示 tlp-stat 中 S.M.A.R.T. 数据。

  1. $ sudo zypper install smartmontools

成功安装 TLP 后，使用以下命令启动服务。

  1. $ systemctl start tlp.service
