June 11, 2025: Version 2.3.0

Added Get-LnvUpdateNotification, Get-LnvMTOSList, Add-LnvMTOS, Remove-LnvMTOS cmdlets. These allow you to create a list of Machine Type + OS combinations you care about and keep track of what updates have been added to their System Update catalogs since the last time you checked.
Added Get-LnvWUFriendlyName cmdlet that provides a list of the drivers and firmware installed by Windows Update with their associated Device Names to make it easier to tell what Windows Update is providing.
Added -DeltaUpdate option to Get-LnvUpdatesRepo which will allow you to just download new updates to an existing repository.
Fixed error handling when system does not have a battery in Get-LnvBatteryInfo.

February 26, 2025: Version 2.2.0

Added Find-LnvHSAPack cmdlet. This cmdlet lets you see what HSA packs have been released for a specified Machine Type.
Added Release Date to the return from Find-LnvUpdate.
Added DownloadPath parameter to Get-LnvDriverPack so you can control where the package is downloaded to.
Fixed issue that occurs if a driver pack for the OS Build Version specified is not found in Get-LnvDriverPack.
Changed to display size in MB in Get-LnvUpdatesRepo.
Added CloudRepo as a switch parameter for Get-LnvUpdatesRepo to generate the repository as a Lenovo Cloud repository (the update packages are left on Lenovo's site).
Fixed an issue with Get-LnvUpdatesRepo if ran without specifying -WindowsVersion.

December 11, 2024: Version 2.1.0

Now available in the PowerShell Gallery. Use Install-Module -Name Lenovo.Client.Scripting to install from the gallery.
Added Find-LnvTool to get URL and version information for the installer packages of our tools: Dock Manager, System Update, Thin Installer, Update Retriever

Added -DownloadPath option to Get-LnvDriverPack; will download to $env:TEMP if not specified.
Added -ListAll option to Find-LnvUpdate to get an object containing all the available updates based on any filtering parameters used.
Now leveraging BITS Transfers for downloads of package files in Get-LnvDriverPack, Get-LnvUpdate and Get-LnvUpdatesRepo
Get-LnvAvailableBiosVersion received several improvements (improved Win11/Win10 catalog handling, added -DownloadPath, added release date).

November 7, 2024: Version 2.0.0

Changed name to Lenovo.Client.Scripting to avoid confusion with Lenovo Device Manager product. This version supersedes all prior versions of the Lenovo Device Management Module (LDMM).
Added new cmdlets - Get-LnvBiosInfo, Find-LnvBiosInfo, Get-LnvWarranty
Made several fixes to Get-LnvUpdatesRepo. The ScanOnly option is no longer available. Added -PackageList as a parameter to specify specific updates by Package ID.

Installation & Setup#

PowerShell Gallery (Recommended)

As of December 11, 2024, LCSM is published in the PowerShell Gallery for easy installation.

Installation:

Install-Module -Name Lenovo.Client.Scripting -Force
Import-Module Lenovo.Client.Scripting

Verify installation:

Get-Module Lenovo.Client.Scripting

Manual Installation

The module itself is currently available for manual download here: Lenovo.Client.Scripting_2.4.2.zip

The zip file contains the Lenovo.Client.Scripting module folder with: - Lenovo.Client.Scripting.psm1 : module script - Lenovo.Client.Scripting.psd1 : module manifest - Public folder : individual PowerShell scripts for public functions - Private folder : individual PowerShell scripts for private functions

Extract the Lenovo.Client.Scripting folder to one of these module locations:

Per User: %UserProfile%\Documents\WindowsPowerShell\Modules
All Users: %ProgramFiles%\WindowsPowerShell\Modules

Removing Legacy Modules & Importing LCSM

If you previously used the Lenovo Device Management Module (LDMM), remove it first:

Remove-Module LnvDeviceManagement

Import the LCSM module:

Import-Module Lenovo.Client.Scripting -Force

Verify the module is loaded:

Get-Module Lenovo.Client.Scripting

Troubleshooting & Common Issues#

Module Won't Import

Error: The term 'Lenovo.Client.Scripting' is not recognized

Solutions:

Verify PowerShell is version 5.1 or higher: $PSVersionTable.PSVersion
Check module is in correct path: $env:PSModulePath
Use -Force flag on import: Import-Module Lenovo.Client.Scripting -Force
Try refreshing the module cache: Update-Module Lenovo.Client.Scripting

Cmdlet Returns Empty Results

Possible causes:

Invalid machine type - verify with Get-LnvMachineType on the target device
No internet connection - many cmdlets require access to Lenovo catalogs
Regional restrictions - some updates may not be available in your region
Incorrect Windows version parameter - ensure you specify "10" or "11", not "Windows 10"

Get-LnvUpdatesRepo Takes Too Long

Optimization tips:

Specify -PackageTypes to limit which types to download (e.g., "2,3" for drivers and BIOS only)
Use -DeltaUpdate parameter (v2.2.0+) to download only new updates to existing repository
Use -CloudRepo parameter to skip downloading package files (metadata only)

BIOS Password / Get-LnvBiosPasswordsSet Requires Admin

Error: THIS CMDLET REQUIRES ADMIN RIGHTS

Solution: Run PowerShell as Administrator before executing the cmdlet.

Show-LnvApplicableUpdate File Not Found

Locations to check:

Thin Installer: C:\Program Files (x86)\Lenovo\Thin Installer\logs\Update_ApplicabilityRulesTrace.txt
System Update: %ProgramData%\Lenovo\Vantage\AddinData\LenovoSystemUpdateAddin\logs\ApplicabilityRulesTrace.txt
Custom location: Use full path if logs are stored elsewhere
