 # lapctl
 
-**lapctl** is an upcoming command-line utility written in Rust for managing laptop hardware features on Linux.
+**lapctl** is a powerful, dependency-free command-line utility written in Rust. It is designed to provide seamless hardware management for Linux laptops. 
 
-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.
+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.

-## Planned Features
+## Key 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)
+- **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.
