Updating
Lenovo Legion Toolkit can update itself automatically or be updated manually:
- Automatic In-App Updates: Configure in Settings $\rightarrow$ Updates:
- Channel: Choose between Stable, Beta, or Dev releases.
- Frequency: Set background check intervals (Daily, Weekly, Hourly, etc.).
- Seamless In-Place Upgrades: You never need to uninstall previous versions. Installing over an existing version preserves all settings, custom modes, actions, and macros.
- Integrity Protection: All automated updates are cryptographically verified with Authenticode signatures prior to installation.
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.
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:
- Lenovo Energy Management
- Lenovo Vantage Gaming Feature Driver
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:
- Go to https://dotnet.microsoft.com/en-us/download/dotnet/9.0
- Find section “.NET Desktop Runtime”
- Download x64 Windows installer
- Run the installer
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.

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.
Using the disable option in LLT is often the easiest option.
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.
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
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:
- 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
- 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:
- 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
- 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, before switching between Hybrid Modes in case you encounter problems.
All above settings are using built in functions of the EC and how well they work relies on Lenovo’s firmware implementation. From our observations, they are reliable, unless you start switching them frequently. Be patient, because changes to these methods are not instantaneous. LLT also attempts to mitigate these issues, by disallowing frequent Hybrid Mode switching and additional attempts to wake dGPU if EC failed to do so. It may take up to 10 seconds for dGPU to reappear when switching to Hybrid Mode, in case EC failed to wake it.
If you encounter issues, you might try an alternative, experimental method of handling GPU Working Mode - see Arguments section for more details.
Disabling dGPU via Device Manager DOES NOT disconnect the device and will cause high power consumption!
Deactivate discrete NVIDIA GPU
Sometimes discrete GPU stays active even when it should not. This can happen for example, if you work with an external screen and you disconnect it - some processes will keep running on discrete GPU keeping it alive and shortening battery life.
There are two ways to help the GPU deactivate:
- killing all processes running on dGPU (this one seems to work better),
- disabling dGPU for a short amount of time, which will force all processes to move to the integrated GPU.
Deactivate button will be enabled when dGPU is active, you have Hybrid mode enabled and there are no screens connected to dGPU. If you hover over the button, you will see the current P state of dGPU and the list of processes running on it.
Some apps may not like this feature and crash when you use deactivate dGPU option.
Overclock discrete NVIDIA GPUs
The overclock option is intended for simple overclocking, similar to the one available in Vantage. It is not intended to replace tools like Afterburner. Here are some points to keep in mind:
- Make sure GPU overclocking is enabled in BIOS, if your laptop has such option.
- Overclocking does not work with Vantage or LegionZone running in the background.
- It is not recommended to use the option while using other tools like Afterburner.
- If you edited your Dashboard, you might need to add the control manually.
Windows Power Plans & Windows Power Mode
First of all, the Power Mode you see in LLT (or toggle with Fn+Q) is not the same as Power Plans (that you access from Control Panel) or Power Mode (that you can change from Settings app).
The modern (and recommended) approach is to use Windows Power Modes and only one, default, “Balanced (recommended)” power plan. You should have 3 Power Modes to choose from in Windows Settings app:
- Best power efficiency
- Balanced
- Best performance
You can assign these in LLT settings to each of Legion Power Modes: Quiet, Balance, Performance and Custom. If you choose to do so, respective Windows Power Mode will be automatically set when you change Legion Power Modes.
The legacy approach is to use multiple Power Plans, that some devices had installed from factory. If you decide to use them, or configure your own plans, leave the settings in Windows Settings app on the default “Balanced” setting. You can configure LLT to switch Power Plans automatically whenever you change the “Legion” Power Mode in LLT settings.
If you encounter issues with power mode or plan synchronization, especially when switching between the two approaches, you can reset Windows power settings to default using powercfg -restoredefaultschemes; shutdown /r /t command. This command will reset all power plans to default and reboot your device. All plans except for the default “Balanced (recommended)” will be deleted, so make sure to make a copy, if you plan on using them again.
Boot Logo
On some laptops, it is possible to change the boot logo (the default “Legion” image you see at boot). Boot logo is not stored in UEFI - it is stored on the UEFI partition on boot drive. When setting custom boot logo, LLT conducts basic checks, like resolution, image format and calculates a checksum to ensure compatibility. However, the real verification happens on the next boot. UEFI will attempt to load the image from UEFI partition and show it. If that fails for whatever reason, default image will be used. Exact criteria, except for resolution and image format, are not known and some images might not be shown. In this case, try another image, edited with different image editor.
Running programs or scripts from actions
You can use “Run” step in Actions to start any program or script from Actions. To configure it, you need to provide path to the executable (.exe) or a script (.bat). Optionally, you can also provide arguments that the script or program supports - just like running anything from command line.
Examples
Shutdown laptop
- Executable path:
shutdown
- Arguments:
/s /t 0
Restart laptop
- Executable path:
shutdown
- Arguments:
/r
Running a program
- Executable path:
C:\path\to\the\program.exe (if the program is on your PATH variable, you can use the name only)
- Arguments:
(optional, for list of supported argument check the program’s readme, website etc.)
Running a script
- Executable path:
C:\path\to\the\script.bat (if the script is on your PATH variable, you can use the name only)
- Arguments:
(optional, for list of supported argument check the script’s readme, website etc.)
Python script
- Executable path:
C:\path\to\python.exe (or just python, if it is on your PATH variable)
- Arguments:
C:\path\to\script.py
Environment
LLT automatically adds some variables to the process environment that can be accessed, from within the script. They are useful for more advanced scripts, where context is needed. Depending on what was the trigger, different variables are added.

Output
If “Wait for exit” is checked, LLT will capture the output from standard output of the launched process. This output is stored in $RUN_OUTPUT$ variable and can be displayed in Show notification step.
CLI
It is possible to control some features of LLT directly from the command line. The CLI executable is called llt.exe and can be found in the install directory.
For CLI to work properly, LLT needs to run in the background and CLI option needs to be enabled in LLT settings. You can also choose to add llt.exe to your PATH variable for easier access.
CLI does not need to be run as Administrator.

C# Script Console
The Script Console is enabled by starting LLT with --debug (see Arguments) and is available in Settings → App Behavior. It executes C# snippets inside the running application, with access to LenovoLegionToolkit.Lib, its controllers and the application state. Output, return value, execution time and any compilation or runtime errors are shown in the window.
Intended for advanced debugging only. Scripts run in the application’s own process, so a misbehaving script can destabilize it. The script validator blocks file system, network, registry, WMI, reflection and process APIs, and rejects #r directives.

FAQ
Why do I get a message that Vantage is still running, even though I uninstalled it?
Starting from version 2.14.0, LLT is much more strict about detecting leftover processes related to Vantage. Vantage installs 3 components:
- Lenovo Vantage app
- Lenovo Vantage Service
- System Interface Foundation V2 Device
The easiest solution is to go into LLT settings and select options to disable Lenovo Vantage, Legion Zone and Hotkeys (only still installed ones are shown).
If you want to remove them instead, make sure that you uninstall all 3, otherwise some options in LLT will not be available. You can check Task Manager for any processes containing Vantage or ImController. You can also check this guide for more info: Uninstalling System Interface Foundation V2 Device, if you have troubles getting rid of ImController processes.
Why is my antivirus reporting that the installer contains a virus/trojan/malware?
LLT makes use of many low-level Windows APIs that can be falsely flagged by antiviruses as suspicious, resulting in a false-positive. LLT is open source and can easily be audited by anyone who has any doubts as to what this software does. All installers are built directly on GitHub with GitHub Actions, so that there is no doubt what they contain.
To ensure authenticity, the installer executable and Lenovo Legion Toolkit.exe itself is signed with a project certificate. This signature allows the application’s custom updater to verify that the installer hasn’t been tampered with and originated from the official build process.
If you downloaded the installer from this project’s website or GitHub, you shouldn’t worry - the warning is a false-positive.
Can I customize hotkeys?
You can customize hotkeys in LLT settings.
Can I customize Conservation mode threshold?
No. Conservation mode threshold is set in firmware to 60% (2021 and earlier) or 80% (2022 and later) and it can’t be changed.
No, it isn’t possible to customize how the fan works in power modes other than Custom.
Starting with version 2.11.0, LLT’s behavior was aligned with Vantage and Legion Zone and it does not allow using them without an appropriate power source.
If for whatever reason you want to use these modes on battery anyway, you can use --allow-all-power-modes-on-battery argument. Check Arguments section for more details.
Power limits and other settings are not applied correctly on most devices when laptop is not connected to full power AC adapter and unpredictable and weird behavior is expected. Therefore, no support is provided for issues related to using this argument.
It seems that some BIOS versions indeed have weird issues when using Fn+Q. Only hope is to wait for Lenovo to fix it.
Why am I getting incompatible message after motherboard replacement?
Sometimes new motherboard does not contain correct model numbers and serial numbers. You should try this tutorial to try and recover them. If that method does not succeed, you can workaround it with --skip-compat-check argument. Check Arguments section for more details.
Game detection mode can be configured in LLT settings. There are four options:
- Auto (default) — combines all methods below
- Discrete GPU — reacts when any process starts using the discrete GPU
- Game Config Store — reacts to games registered in Windows via Xbox Game Bar (
HKEY_CURRENT_USER\System\GameConfigStore\Children). You can mark any program as a game in Xbox Game Bar settings (Win+G)
- Game Mode — reacts when Windows activates Game Mode for the foreground process
If a game is not detected, check which detection mode is configured in LLT settings and ensure the game meets the criteria for that mode.
Can I use other RGB software while using LLT?
In general, yes. LLT will disable RGB controls when Vantage is running to avoid conflicts. If you use other RGB software like L5P-Keyboard-RGB or OpenRGB, you can disable RGB in LLT to avoid conflicts with --force-disable-rgbkb or --force-disable-spectrumkb argument. Check Arguments section for more details.
Will iCue RGB keyboards be supported?
No. Check out OpenRGB project.
Can I have more RGB effects?
Only options natively supported by hardware are available; adding support for custom effects is not planned. If you would like more customization check out L5P-Keyboard-RGB or OpenRGB.
Can you add fan control to other models?
Fan control is available on Gen 7 and later models. Older models will not be supported due to technical limitations. For discussions about fan control experimental support, join the Official Discord.
In Windows 10 and 11, Microsoft did plenty of changes to the tray, breaking a lot of things on the way. As a result, custom tooltips do not always work properly. Solution? Update your Windows and keep fingers crossed.
How can I OC/UV my CPU?
There are very good tools like Intel XTU (which is used by Vantage) or ThrottleStop made just for that.
What if I overclocked my GPU too much?
If you end up in a situation where your GPU is not stable and you can’t boot into Windows, there are two things you can do:
- Go into BIOS and try to find an option similar to “Enabled GPU Overclocking” and disable it, start Windows, and toggle the BIOS option again to Enabled.
- Start Windows in Safe Mode, and delete
gpu_oc.json file under LLT settings, which are located in "%LOCALAPPDATA%\LenovoLegionToolkit.
Why is my Boot Logo not applied?
When you change the Boot Logo, LLT verifies that it is in the correct format and correct resolution. If LLT shows that boot logo is applied, it means that the setting was correctly saved to UEFI. If you don’t see the custom boot logo, it means that even though UEFI is configured and custom image is saved to UEFI partition, your UEFI for some reason does not render it. In this case the best idea is to try a different image, maybe in different format, edited with different image editor etc. If the boot logo is not shown after all these steps, it’s probably a problem with your BIOS version.
Why do I see stuttering when using Smart Fn Lock?
On some BIOS versions, toggling Fn Lock causes a brief stutter and since Smart Fn Lock is basically an automatic toggle for Fn Lock, it is also affected by this issue. Try disabling “Fool proof Fn Lock” (or similar) option in BIOS - it was reported that it fixes stutter when toggling Fn Lock.
In latest version LLT removes this feature for Chinese models due to increasing unreliability. If you got warranty infos before it should be displayed normally, but after manually refreshing or deleting stored data the infos will disappear. This change only affects users with a Chinese Legion laptop.
Which generation is my laptop?
Check the model number. Example model numbers are 16ACH6H or 16IAX7. The last number of the model number indicates generation.
