laptop-battery-actions

A script that reacts to acpid events and does the following

• Set backlight brightness to the battery level - decreasing brightness is a good battery-level indicator and a really dim screen means you ought to plug in sometime soon.
• Invokes tlp and pm-powersave powersave configurations when battery is discharging or to optimized otherwise.
• Hibernates the laptop on a critically low battery level.

Installation

sudo -E ./INIT
