使用tlp优化电池消耗
目录
TLP是一款linux上的基于文本界面的高级电源管理工具。TLP默认提供了一套针对电池使用进行优化的配置,使用这套配置能够显著降低对电池的消耗。 此外TLP也具有很高的可配置性，能够让你充分的配置以满足特殊需求。
安装TLP
在archlinux上通过下面命令来安装：
sudo pacman -S tlp tlp-rdw --noconfirm

启动TLP服务
TLP默认会启动 NetworkManager.service,然而我使用的是 netctl 来管理网络，因此还需要修改一下 tlp.service
sudo cp /usr/lib/systemd/system/tlp.service /etc/systemd/system/
sudo sed -i '/Wants/ s/NetworkManager.service//' /etc/systemd/system/tlp.service
我们希望由TLP来管理无线设备，因此还需要mask systemd-rfkill.service 和 systemd-rfkill.socket
sudo systemctl mask systemd-rfkill.service sudo systemctl mask systemd-rfkill.socket
启动TLP服务
sudo systemctl start tlp.service sudo systemctl enable tlp.service sudo systemctl start tlp-sleep.service sudo systemctl enable tlp-sleep.service
我们可以通过 tlp-stat 来检查TLP是否已经启动
sudo tlp-stat -s
--- TLP 1.1 -------------------------------------------- +++ System Info System = LENOVO ThinkPad X61 7673A98 BIOS = 7NET29WW (1.10 ) Kernel = 4.16.3-1-ARCH #1 SMP PREEMPT Thu Apr 19 09:17:56 UTC 2018 x86_64 /proc/cmdline = BOOT_IMAGE=/boot/vmlinuz-linux root=UUID=8011a945-7d06-4735-9eb1-7c7d9f10febf rw quiet Init system = systemd Boot mode = BIOS (CSM, Legacy) +++ TLP Status State = enabled Last run = 11:08:28 PM, 441 sec(s) ago Mode = AC Power source = AC
如果TLP没有启动的话，可以执行手工启动TLP
sudo tlp start
TLP started in AC mode.
使用TLP
TLP中最常用的命令有这么几个：
tlp: 应用笔记本的节能设置。
- sudo tlp start
- 根据实际情况是使用交流电还是电池，来应用对应的节能设置
- sudo tlp ac
- 强制切换到交流电对应的节能设置
- sudo tlp bat
- 强制切换到电池的节能设置
tlp-stat: 显示当前的节能设置
- sudo tlp-stat -b
- 显示电池的相关信息
- tlp-stat -c
- 显示tlp当前的配置信息
- sudo tlp-stat -d
- 显示磁盘的信息
- sudo tlp-stat -e
- 显示PCIE信息
- sudo tlp-stat -g
- 显示显卡的相关信息
- tlp-stat -r
- 显示无线设备的相关信息
- tlp-stat -s
- 显示系统相关信息
- tlp-stat -t
- 显示温度和磁盘转速
- tlp
- 显示上面的所有信息
wifi: 手动启动/关闭wifi
- sudo wifi on
- 手动启动wifi
- sudo wifi off
- 手动关闭wifi
- sudo wifi toggle
- 手动切换wifi状态
bluetooth: 手动启动/关闭蓝牙

配置TLP
TLP的配置文件放在 /etc/default/tlp 中，详细的配置方法请参见官网上的说明
TLPUI
TLP本身并不自带图形化用户界面，但是有一个第三方的GTK GUI界面可以使用，名叫 TLPUI
archlinux的aur仓库中就有这个应用,可以通过下面这个命令来安装
aurman -S tlpui-git
安装后直接运行 tlpui 就能打开应用
