Bash script for energy management on Lenovo IdeaPad 5 14ARE05 laptops

Lenovo IdeaPad 5 14ARE05 energy management script

This is a bash script that utilizes acpi calls to control certain energy-related aspects of Lenovo Ideapad 5 14ARE05 laptops:

• rapid charge
• battery conservation (limits the maximum charge of the battery at the level of 55-60% to prolong the life of the battery)
• functioning mode:
  • intelligent cooling
  • extreme performance
  • battery saving

Pre-requisites

The script relies on the ACPI calls and uses for that purpose the functionality of the /proc/acpi/call which in turn is provided by the acpi_call packet and hence must be installed in order for script to work.

Installation

In order to install the script into the system the following command must be executed with root priviledges:

sudo make install

It will do the following:

• it will copy ideapad5_14are05_energy_mgmt.sh into the /usr/local/bin directory
• change the owner of the ideapad5_14are05_energy_mgmt.sh to the root:root
• create a file in the /etc/sudoers.d/ideapad5_14are05_energy_mgmt that will allow current user to run the script with sudo but no password (if you don't need this - just remove the file)

Uninstall

In order to uninstall the following command must be executed:

sudo make uninstall
