LenovoLegion

Unofficial control application for Legion Pro 7 16IRX9H with Core™ i9-14900HX and NVIDIA GeForce RTX 4090 GPU.

This project is not affiliated with Lenovo in any way Lenovo Legion brings additional drivers and tools for Legion Pro 7 16IRX9H with Core™ i9-14900HX and NVIDIA GeForce RTX 4090 GPU to Linux. It is the alternative to Lenovo Vantage or Legion Zone (both Windows only). It allows you to control features like the fan curve, power mode, power limits, and more. This has been achieved through reverse engineering and disassembling the ACPI firmware, as well as the firmware and memory of the embedded controller (EC).

[ 3.980258] lenovo-legion VPC2004:00: Legion Pro 7 16IRX9H platform driver was loaded

This module is responsible about comunication with HW  your fan, power on GPU and CPU, temperature limits,  switch modes (QUIET, BALANCED, PERFORMANCE, CUSTOM).  Is neccessary if you need adjust this components. I think it will be compatible with same laptop where is GeForce RTX 4080.

Supported kernels (tested): since 6.12 . I use 6.16.4-2-cachyos kernel and works fine.
