Install-LenovoUpdates

Overview​

This PowerShell script automates the discovery and installation of Lenovo-specific updates (BIOS, drivers, firmware, applications) on supported workstations. It solves the problem of manually managing Lenovo system updates in enterprise environments by providing a standardized, automated approach with comprehensive logging and reboot control.

Important Notes​

  • Forceful reboots: BIOS/firmware updates initiate hardware-level restarts that bypass -NoReboot parameter controls
  • Maintenance windows: Schedule updates during planned downtime to avoid disruption
  • Power continuity: Ensure uninterrupted power supply during firmware updates
  • Unattended requirement: Type-based installations only process updates supporting silent installation
  • ID exceptions: Updates installed by ID ignore unattended installation requirements

Requirements​

  • Administrative privileges: Must be run as administrator
  • Lenovo hardware: Designed exclusively for Lenovo workstations
  • Supported OS: Windows 10 or Windows 11
  • PowerShell 5.1+: Minimum required PowerShell version
  • Internet connectivity: Required for module installation and update downloads

The script executes through these stages:

  1. Environment Setup:

    • Configures TLS 1.2 security protocol
