Battery manager to handle system performance modes and charge modes through acpi_calls (for ideapad 15are05/14are05/14alc05/14sARH).

Motivation

On Windows native software to support battery and performance operations exist, on GNU/Linux, it's possible to handle system performance modes and battery charge modes making acpi_calls manually. This script makes it easy to manage such operations.

Contributing

battmngr seem to be working fine on the supported devices, but only because ACPI calls values were publicly known.

If you know any way of discovering ACPI calls values for specific laptop models, please open an issue detailing your process. This could help supporting many more potentially compatible laptops.

Note

When in configuration:

issuing the command battmngr -sc 1 will turn on Rapid Charge mode but disable Battery Conservation mode. It's possible to activate both Rapid Charge and Battery Conservation modes starting from configuration:

and issuing the command battmngr -sc 3
This configuration is not obtainable using official lenovo software and should be avoided.
