Save battery power on laptops
TLP is an advanced power management tool for Linux. It comes with a
default configuration already optimized for battery life. At the same
time it is highly customizable to fulfil specific user requirements.
.
TLP supplies separate settings profiles for AC and battery power and can
enable or disable bluetooth, WiFi and WWAN radio devices upon system startup.

For ThinkPads it provides a unified way to configure charging thresholds and
recalibrate the battery for all models which support it (via tp-smapi or
acpi-call).

TLP is a pure command line tool with automated background tasks, it
does not contain a GUI.
