Legion Laptop Toolkit CLI (LLTC)

A lightweight, command-line-only tool to control a couple of features that are only available in Lenovo Vantage or Legion Zone with no background service.

ℹ️ Note: This project is actively maintained and was inspired by the now-archived LenovoLegionToolkit (LLT). Special thanks to @BartoszCichecki and the LLT community for their foundational work on Lenovo laptop control interfaces.
