Get-LnvDownload#

Downloads Lenovo update packages and optionally extracts them to a local folder.

Synopsis#

Downloads driver, BIOS, firmware, and application updates for a specified Lenovo machine type and creates a local folder.

Description#

Get-LnvDownload is a function that downloads Lenovo update packages directly from Lenovo's servers for a specific machine type. It creates a local folder structure and can optionally extract package installers using the -Expand parameter.

This function downloads packages to individual folders named by package ID and stores them in the specified folder. When -Expand is used, the installer files are extracted directly into each package folder.

Note

This function was migrated from the Lenovo.Client.Scripting module and will be maintained in this module going forward. For more flexible workflows, consider using Get-LnvUpdate, Save-LnvUpdate, and Expand-LnvUpdate separately.

Warning

The -Expand parameter requires running PowerShell as Administrator.

  ├── packageID2\
  │   └── ...
  └── MachineType_WindowsVersion.csv  ← If -Csv used

Examples#

Example 1: Download drivers for a machine type#

Get-LnvDownload -MachineType 21HM -WindowsVersion 11 -RepositoryFolder "C:\Drivers\21HM"

Downloads all available packages for ThinkPad machine type 21HM running Windows 11.

Example 2: Download only drivers and applications#

Get-LnvDownload -MachineType 20E4 -PackageType "1,2" -RepositoryFolder "C:\Updates"

Downloads only applications (1) and drivers (2), excluding BIOS and firmware.

Example 3: Download and extract packages#

Get-LnvDownload -MachineType 21N2 -WindowsVersion 11 -RepositoryFolder "E:\LCU\21N2" -Csv -Expand

Downloads packages and extracts installers. Requires running PowerShell as Administrator. Creates a CSV file listing all packages with their properties.

Example 4: Download drivers with specific reboot types#

$path = "E:\Drivers\ThinkPad"
Get-LnvDownload -MachineType 21HM -WindowsVersion 11 -RepositoryFolder $path -PackageType "2" -RebootType "0,3" -Expand

Downloads only drivers that either don't require reboot (0) or require reboot (3), then extracts them.

Notes#

Package Type Values#

1 - Application
2 - Driver
3 - BIOS
4 - Firmware
9 - All (default)

Reboot Type Values#

0 - No reboot required.
1 - The update will force the system to reboot. This cannot be prevented if you install this update.
3 - Reboot recommended.
4 - The update will force the system to power off. This cannot be prevented if you install this update.
5 - Reboot required immediately. Allows for multiple updates to be installed and serviced by one reboot.

Extraction Behavior#

When using -Expand:

Extraction happens in the background using PowerShell runspaces
Progress messages display every 5 seconds
Extracted files are placed directly in each package folder
The function waits for all extractions to complete before exiting
