Dear unixmen readers,
If you are looking for an advanced power management tool for your Linux laptop and you don’t like to worry much about technical details, TLP is the right tool for you. It comes with a default configuration that will help to improve your battery life, so if you don’t like to run any customization just install it, and let the TLP tool work for you. Unfortunately, the TLP tool does not contain a GUI, it is a pure command line tool that many linux geeks will like to use from their terminal.
The followings are the changes included in the TLP release:
- tpacpi-bat: auto detection of all ThinkPad models (v2.1)
- tlp-stat: include newer models in tpacpi-bat suggestions
- tlp-rdw: support newer docks
- Handle special case where BAT1 = main battery (Thinkpad Edge/L/S series)
- Fix: sound power save depending on power source ac/bat
- Fix: don’t touch devices in RUNTIME_PM_BLACKLIST or excluded by RUNTIME_PM_ALL=0
- Fix: do not write sata link power when not configured
- Fix RESTORE_DEVICE_STATE_ON_STARTUP
- Restore bay power state upon resume only when on bat power and the setting is active
- Use nmcli before rfkill to change radio state
- re-enable wifi on shutdown when not explicitly configured (Ubuntu 14.04)
If you want to install TLP in your Ubuntu machine, then open a new terminal(CTRL+ALT+T) and run the following commands.
sudo add-apt-repository ppa:linrunner/tlp sudo apt-get update sudo apt-get install tlp tlp-rdw
