Managing Lenovo BIOS Settings (Part 2)

by Sep 4, 2018

In the previous tip, we explained how to dump all BIOS settings for Lenovo computers. To change settings, you need to know the supported alternatives for a given setting. Here is a chunk of code that dumps the list of available options for a given BIOS settings (for Lenovo computers):

#requires -RunAsAdministrator

# this is case-sensitive
$Setting = "WakeOnLAN"

$selections = Get-WmiObject -Class Lenovo_GetBiosSelections -Namespace root\wmi

Note that this code requires Administrator privileges. Also, the setting name is case-sensitive. The result may look similar to this:


And this would be a complete example showing how to retrieve the current BIOS settings, plus the list of legal settings:

#requires -RunAsAdministrator

$selections = Get-WmiObject -Class Lenovo_GetBiosSelections -Namespace root\wmi

Get-WmiObject -Class Lenovo_BiosSetting -Namespace root\wmi | 
Where-Object CurrentSetting |
ForEach-Object {
    $parts = $_.CurrentSetting.Split(',')
        CurrentSetting = $parts[0]
        Status = $parts[1]
        Active = $_.Active
        AvailableSettings = $selections.GetBiosSelections($parts[0]).Selections.Split(',')
} | Out-GridView

The result may look similar to this:
