Lenovo Legion Toolkit (LLT) is a utility created for Lenovo Legion (and similar) series laptops, that allows changing a couple of features that are only available in Lenovo Vantage or Legion Zone.

It runs no background services, uses less memory, uses virtually no CPU, and contains no telemetry. Just like Lenovo Vantage, this application is Windows only.

This is actually a fork of original project which development stopped some time ago. But it's great to see that someone took over the job of developing this great tool.

Critical Upgrade Instructions (Read Before Installing)​

Due to the extensive architectural overhauls in how power modes, plan overrides, and plugin caches are handled in this version, legacy configuration files are highly likely to conflict with the new system. To avoid erratic behavior, power state desyncs, or the side effects of unbalanced configurations, you must follow one of the two paths outlined below when upgrading.

Option 1: Clean Installation (Recommended)​

  1. Completely uninstall your existing version of the application.
  2. Manually delete all leftover configuration files and directories.
  3. Install the new version fresh.

Option 2: In-Place Upgrade with Reset​

  1. Install the new version directly over your existing installation.
  2. Open the application and immediately navigate to Settings.
  3. Use the newly added Reset Settings option to wipe your old profile and revert the app to its safe, default configuration.
Failure to perform a reset or a clean installation will result in configuration conflicts that can cause unintended power and sensor behavior. Please do not skip this step.
