多年來，Linux 在電池最佳化方面取得了很大進步，但我們仍然需要做一些必要的事情來改善 Linux 中膝上型電腦的電池壽命。

— Magesh Maruthamuthu

 

筆記本電池是針對 Windows 作業系統進行了高度最佳化的，當我在膝上型電腦中使用 Windows 作業系統時，我已經意識到這一點，但對於 Linux 來說卻不一樣。

多年來，Linux 在電池最佳化方面取得了很大進步，但我們仍然需要做一些必要的事情來改善 Linux 中膝上型電腦的電池壽命。

當我考慮延長電池壽命時，我沒有多少選擇，但我覺得 TLP 對我來說是一個更好的解決方案，所以我會繼續使用它。

在本教程中，我們將詳細討論 TLP 以延長電池壽命。

我們之前在我們的網站上寫過三篇關於 Linux 筆記本電池節電工具 的文章：PowerTOP 和 電池充電狀態。

TLP

TLP 是一款自由開源的高階電源管理工具，可在不進行任何配置更改的情況下延長電池壽命。

由於它的預設配置已針對電池壽命進行了最佳化，因此你可能只需要安裝，然後就忘記它吧。

此外，它可以高度定製化，以滿足你的特定要求。TLP 是一個具有自動後臺任務的純命令列工具。它不包含GUI。

TLP 適用於各種品牌的膝上型電腦。設定電池充電閾值僅適用於 IBM/Lenovo ThinkPad。

所有 TLP 設定都儲存在 /etc/default/tlp 中。其預設配置提供了開箱即用的最佳化的節能設定。

以下 TLP 設定可用於自定義，如果需要，你可以相應地進行必要的更改。

TLP 功能

◈ 核心膝上型電腦樣式和臟緩衝區超時
◈ 處理器頻率調整，包括 “turbo boost”/“turbo core”
◈ 限制最大/最小的 P 狀態以控制 CPU 的功耗
◈ HWP 能源效能提示
◈ 用於多核/超執行緒的功率感知行程排程程式
◈ 處理器效能與節能策略（x86_energy_perf_policy）
◈ 硬碟高階電源管理級別（APM）和降速超時（按磁碟）
◈ AHCI 鏈路電源管理（ALPM）與裝置黑名單
◈ PCIe 活動狀態電源管理（PCIe ASPM）
◈ PCI(e) 匯流排裝置的執行時電源管理
◈ Radeon 圖形電源管理（KMS 和 DPM）
◈ Wifi 省電樣式
◈ 關閉驅動器托架中的光碟驅動器
◈ 音訊省電樣式
◈ I/O 排程程式（按磁碟）
◈ USB 自動暫停，支援裝置黑名單/白名單（輸入裝置自動排除）
◈ 在系統啟動和關閉時啟用或禁用整合的 wifi、藍芽或 wwan 裝置
◈ 在系統啟動時恢復無線電裝置狀態（從之前的關機時的狀態）
◈ 無線電裝置嚮導：在網路連線/斷開和停靠/取消停靠時切換無線電
◈ 禁用 LAN 喚醒
◈ 掛起/休眠後恢復整合的 WWAN 和藍芽狀態
◈ 英特爾處理器的動態電源降低 —— 需要內核和 PHC-Patch 支援
◈ 電池充電閾值 —— 僅限 ThinkPad
◈ 重新校準電池 —— 僅限 ThinkPad

如何在 Linux 上安裝 TLP

TLP 包在大多數發行版官方儲存庫中都可用，因此，使用發行版的 包管理器 來安裝它。

對於 Fedora 系統，使用 DNF 命令 安裝 TLP。

  1. $ sudo dnf install tlp tlp-rdw

ThinkPad 需要一些附加軟體包。

  1. $ sudo dnf install https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm
  2. $ sudo dnf install http://repo.linrunner.de/fedora/tlp/repos/releases/tlp-release.fc$(rpm -E %fedora).noarch.rpm
  3. $ sudo dnf install akmod-tp_smapi akmod-acpi_call kernel-devel

安裝 smartmontool 以顯示 tlp-stat 中 S.M.A.R.T. 資料。

  1. $ sudo dnf install smartmontools

對於 Debian/Ubuntu 系統，使用 APT-GET 命令 或 APT 命令 安裝 TLP。

  1. $ sudo apt install tlp tlp-rdw

ThinkPad 需要一些附加軟體包。

  1. $ sudo apt-get install tp-smapi-dkms acpi-call-dkms

安裝 smartmontool 以顯示 tlp-stat 中 S.M.A.R.T. 資料。

  1. $ sudo apt-get install smartmontools

當基於 Ubuntu 的系統的官方軟體包過時時，請使用以下 PPA 儲存庫，該儲存庫提供最新版本。執行以下命令以使用 PPA 安裝 TLP。

  1. $ sudo apt-get install tlp tlp-rdw

對於基於 Arch Linux 的系統，使用 Pacman 命令 安裝 TLP。

  1. $ sudo pacman -S tlp tlp-rdw

ThinkPad 需要一些附加軟體包。

  1. $ pacman -S tp_smapi acpi_call

安裝 smartmontool 以顯示 tlp-stat 中 S.M.A.R.T. 資料。

  1. $ sudo pacman -S smartmontools

對於基於 Arch Linux 的系統，在啟動時啟用 TLP 和 TLP-Sleep 服務。

  1. $ sudo systemctl enable tlp.service
  2. $ sudo systemctl enable tlp-sleep.service

對於基於 Arch Linux 的系統，你還應該遮蔽以下服務以避免衝突，並確保 TLP 的無線電裝置切換選項的正確操作。

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

對於 RHEL/CentOS 系統，使用 YUM 命令 安裝 TLP。

  1. $ sudo yum install tlp tlp-rdw

安裝 smartmontool 以顯示 tlp-stat 中 S.M.A.R.T. 資料。

  1. $ sudo yum install smartmontools

對於 openSUSE Leap 系統，使用 Zypper 命令 安裝 TLP。

  1. $ sudo zypper install TLP

安裝 smartmontool 以顯示 tlp-stat 中 S.M.A.R.T. 資料。

  1. $ sudo zypper install smartmontools

成功安裝 TLP 後，使用以下命令啟動服務。

  1. $ systemctl start tlp.service
