Restructure loops, add explicit error handling, improve multi‑line messages, and fix formatting issues. - Enhancements - Use explicit braces for error branches to prevent silent failures - Wrap warning and informational messages in multi‑line `println!` with consistent spacing - Refactor directory reads for Ideapad fallback to avoid nested `let` bindings - Improve parsing and formatting of AMD TDP limit output with clear parentheses - Provide clearer debug logging when writing to threshold files - Bug Fixes - Added missing braces around error handling to ensure proper execution flow - Fixed variable binding scope for `ideapad_entries` to prevent shadowing - Ensured consistent handling of missing `charge_control_end_threshold` across all entries no changes.
lapctl
lapctl is a powerful, dependency-free command-line utility written in Rust. It is designed to provide seamless hardware management for Linux laptops.
By interfacing directly with the Linux kernel and ACPI endpoints, lapctl provides a unified interface for controlling hybrid GPU modes, battery charging thresholds, and thermal/power profiles—all from the terminal.
Key Features
- Hybrid GPU Management: Switch effortlessly between Integrated, Nvidia, and Hybrid graphics modes (Optimus).
- Battery Health: Enforce battery charging thresholds (e.g., 80%) to maximize chemical lifespan.
- Power Profiling: Dynamically adjust ACPI Platform Profiles, CPU scaling governors, and TDP (Wattage) limits.
- Thermal Controls: Direct hardware hooks for proprietary cooling solutions (e.g., Lenovo Ideapad, ASUS).
- Hardware Polling: Comprehensive hardware status checking without heavy daemon dependencies.
