UPDATE September 16th, 2020 - The scripts included in these downloads are currently outdated. I plan to update this post soon with the latest script versions.

Now that I have working BIOS management scripts for Dell, HP, and Lenovo, I figured I would put them all together in a few example task sequences. This post will also act as a hub for my BIOS management posts.

This post is one of 3 posts in my series on managing BIOS settings using PowerShell. I’ve also written about Dell and HP. In this post I’ll be talking about using PowerShell to manage Lenovo BIOS settings.

The script can be downloaded from my GitHub: https://github.com/ConfigJon/Firmware-Management/tree/master/Lenovo

Lenovo, WMI, and PowerShell

Lenovo provides a WMI interface that can be used for querying and modifying BIOS settings on their hardware models. This means that we can use PowerShell to directly view and edit BIOS settings without the need for a vendor specific program. This script uses 6 of the Lenovo provided WMI classes.

This post discusses how to manage Lenovo BIOS passwords using WMI. My goal was to have a script that could change or clear existing passwords and could display a prompt to the screen when manual intervention was required. In this post, I’ll cover the basics of how the script works. I’ll also talk about some limitations of the script and some areas it could be improved in the future
