將PPA加入系統
sudo add-apt-repository ppa:linrunner/tlp
安裝套件
sudo apt-get install tlp tlp-rdw smartmontools ethtool
若為ThinkPad筆電，還需安裝以下
sudo apt-get install tp-smapi-dkms acpi-call-tools
執行以下指令開啟TLP
sudo tlp start
執行 sudo tlp-stat 檢查目前設定
編輯設定檔 /etc/default/tlp
參考http://linrunner.de/en/tlp/docs/tlp-configuration.html的說明，以下為我有更動的項目：
- #Select a cpu frequency scaling governor: ondemand/powersave/performance/conservative
  # Important:
  # - You *must* disable your distribution's governor settings or conflicts will occur
  # - ondemand is sufficient for *almost all* workloads, you should know what you're doing!
  CPU_SCALING_GOVERNOR_ON_AC=performance
  CPU_SCALING_GOVERNOR_ON_BAT=ondemand
- 硬碟待機停止時間：
  # Hard disk spin down timeout:
  # 0: spin down disabled
  # 1..240: timeouts from 5s to 20min (in units of 5s)
  # 241..251: timeouts from 30min to 5.5 hours (in units of 30min)
  # (see 'man hdparm' for details)
  DISK_SPINDOWN_TIMEOUT_ON_AC="0 0"
  DISK_SPINDOWN_TIMEOUT_ON_BAT="60 0"
- 藍牙較少使用，因此設定預設為關閉
  # Radio devices to disable on startup: bluetooth wifi wwan
  DEVICES_TO_DISABLE_ON_STARTUP="bluetooth"
