The changes introduce a robust `BatteryCommands::Limit` implementation that validates user‑provided percentages, writes charge‑control thresholds, and gracefully handles Lenovo Ideapad firmware via the `conservation_mode` fallback. The `lapctl status` command is also updated to display battery‑specific details such as capacity, status, and charge limits, replacing the previous generic placeholder. New Features - Added `BatteryCommands::Limit` handling with range validation (1‑100) and support for multiple `/sys/class/power_supply` entries. - Implemented Ideapad fallback using `conservation_mode` to provide custom charge limits or warnings when unsupported. - Extended `lapctl status` to show charge limit and Conservation Mode for each battery. Enhancements - Added root‑privilege check (`assert_root`) and improved error/debug logging throughout the command. - Restructured directory traversal logic for readability and added `debug!` traces on write failures. - Re‑used status logic to present battery‑specific information instead of a generic placeholder. Bug Fixes - Resolved placeholder status output and proper handling of missing `charge_control_end_threshold` files. - Ensured correct exit codes and clear error messages for invalid percentage inputs.
lapctl
lapctl is an upcoming command-line utility written in Rust for managing laptop hardware features on Linux.
It aims to provide a simple and unified interface for controlling hybrid GPU modes, battery charging limits, and other laptop power features directly from the terminal.
Planned Features
-
Switch GPU modes on hybrid graphics laptops
- Integrated GPU
- Hybrid mode
- NVIDIA GPU
-
Set and manage battery charging limits
-
View laptop hardware and power status
-
Lightweight and fast CLI interface
-
Designed for Linux systems with hybrid GPUs (Optimus)
