The tool comes with no warranty. Use at your own risk.

Please be patient and read through this readme carefully - it contains important information.

Download

You can download the program by the following ways:

• From the Releases page

[!TIP] If you are looking for a Vantage alternative for Linux, check LenovoLegionLinux project out.

Next steps

LLT works best when it's running in the background, so go to Settings and enable Autorun and Minimize on close. Next thing is to either disable Vantage and Hotkeys or just uninstall them. After that LLT will always run on startup and will take over all functions that were handled by Vantage and Hotkeys.

[!WARNING] If you close LLT completely some functions will not work, like synchronizing Windows Power Modes or Windows Power Plans with current Power Mode, Macros or Actions. This is due to the fact that LLT does not run any background services and won't be able to respond to changes.

Required drivers

If you installed LLT on a clean Windows install, make sure to have necessary drivers installed. If drivers are missing, some options might not be available. Especially make sure that these two are installed on your system:

1. Lenovo Energy Management
2. Lenovo Vantage Gaming Feature Driver

[!NOTE] These drivers are not required on Gen 10 and later laptops.

Problems with .NET?

If for whatever reason LLT installer did not setup .NET properly:

1. Go to https://dotnet.microsoft.com/en-us/download/dotnet/9.0
2. Find section ".NET Desktop Runtime"
3. Download x64 Windows installer
4. Run the installer

[!NOTE] If you installed LLT from Scoop, .NET 9 should have been installed automatically as a dependency. If anything fails, use scoop update to update all packages and try to reinstall LLT with --force argument.

After following these steps, you can open Terminal and type: dotnet --info. In the output look for section .NET runtimes installed, in this section you should see something like:

Microsoft.NETCore.App 9.0.0 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]

and

Microsoft.WindowsDesktop.App 9.0.0 [C:\Program Files\dotnet\shared\Microsoft.WindowsDesktop.App]

The exact version number can be different, but as long as it is 9.x.x it should be fine. If after these steps LLT still shows an error on startup that .NET couldn't be found or similar, the problem is on your machine and not with LLT.

Want to help with testing?

Join the Official Discord for the latest updates across several channels:

• #stable-updates - Notifications for official releases.
• #beta-builds - Pre-release versions for broader testing.
• #dev-snapshots - Experimental builds straight from the development branch.

The server also supports issue reporting, feature requests, and hardware-related discussions.

Compatibility

Lenovo Legion Toolkit is made for Lenovo Legion laptops and the Legion Go, and other similar devices like IdeaPad Gaming, LOQ, Lenovo Slim, and ThinkBook, including their Chinese variants (R-series, Y-series).

Generations 6 (2021), 7 (2022), 8 (2023), 9 (2024), 10 (2025), and 11 (2026) are supported, although some features also work on the 5th generation (2020). Issues related to devices older than Gen 6 or that are not Legions are out of scope of this project.

If you are getting an incompatible message on startup, you can check the Contribution section down at the bottom, to see how can you help. Keep in mind, that not always we can make all options compatible with all hardware since we do not have access to it.

Support for other laptops is not planned.

Lenovo's software

Overall the recommendation is to disable or uninstall Vantage, Hotkeys and Legion Zone while using LLT. There are some functions that cause conflicts or may not work properly when LLT is working alongside other Lenovo apps.

[!TIP] Using the disable option in LLT is often the easiest option.

Other remarks

LLT currently does not support installation for multiple users, so if you need to have multiple users on your laptop you might encounter issues. Same goes for accounts without Administrator rights - LLT needs an account with Administrator rights. If you install LLT on an account without such rights, LLT will not work properly.

Features

The app allows to:

• Change settings like power mode, battery charging mode, etc. that are available only through Vantage.
• Spectrum RGB, 4-zone RGB and White backlight keyboards support.
• Monitor dGPU activity (NVIDIA only).
• Highly customizable On-Screen Display (OSD) to monitor system vitals in real-time.
• Define Actions that will run when the laptop is e.g. connected to AC power.
• View battery statistics.
• Control laptop features from command line
• Check for driver and software updates.
• Check warranty status.
• Disable/enable Lenovo Vantage, Legion Zone and Lenovo Hotkeys service without uninstalling them.
• ... and more!

Custom Mode

Custom Mode is available on all devices that support it. You can find it in the Power Mode dropdown as it basically is 4th power mode and it allows for adjusting power limits and fans. Custom Mode can't be accessed with Fn+Q shortcut. Not all features of Custom Mode are supported by all devices.

If you have one of the following BIOSes:

• G9CN (24 or higher)
• GKCN (46 or higher)
• H1CN (39 or higher)
• HACN (31 or higher)
• HHCN (20 or higher)

Make sure to update it to at least minimum version mentioned above for Custom Mode to function properly.

RGB and lighting

Both Spectrum per-key RGB and 4-zone RGB backlight is supported. Vantage and its services need to be disabled to avoid conflicts when communicating with hardware. If you use other RGB apps that might conflict with LLT, check FAQ for solutions.

Other lighting features like both 1 and 3 level white keyboard backlight, panel logo and rear ports backlight are also supported, however there are some constraints:

• GKCN54WW and lower - some lighting features are disabled due to a bug in these BIOS versions causing BSOD
• some (mostly Gen 6) laptops models might not show all options or show options that aren't there - this is due misconfigured BIOS that doesn't report availability of these features

Lighting that required Corsair iCue is not supported by LLT.

[!IMPORTANT] Riot Vanguard DRM (used in Valorant for example) is known to cause issues with RGB controls. If you don't see RGB settings and have it installed, make sure it doesn't run on startup or uninstall it.

Hybrid Mode and GPU Working Modes

[!NOTE] Hybrid Mode/GPU Working Mode options are not Advanced Optimus and work separately from it.

There are two main ways you can use your dGPU:

1. Hybrid mode on - internal laptop display is connected to integrated GPU, discrete GPU will work when needed and power off when not in use, giving better battery life
2. Hybrid mode off (aka dGPU) - internal laptop display is connected directly to discrete GPU, giving best performance but also worst battery life

Switching between two modes requires restart.

On Gen 7 and 8 laptops, there are additional 2 settings for Hybrid mode:

1. Hybrid iGPU-only - in this mode dGPU will be disconnected (think of it like ejecting USB drive), so there is no risk of it using power when you want to achieve best battery life
2. Hybrid Auto - similar to the above, but tries to automate the process by automatically disconnecting dGPU on battery power and reconnecting it when you plug in AC adapter

Discrete GPU may not disconnect, and in most cases will not disconnect, when it is used. That includes apps using dGPU, external monitor connected and probably some other cases that aren't specified by Lenovo. If you use the "Deactivate GPU" option in LLT, make sure that it reports dGPU Powered Off and no external screens are connected
