Hey folks,
Recently @BrightRodger asked is it possible to manage BIOS via JC command - I think it's a pretty cool idea. After a quick research it turns out the BIOS for the big 3 (Lenovo, HP, Dell) all have PowerShell manageability!
Inspired from the articles:
Lenovo BIOS Settings Management
HP BIOS Settings Management
Working with the Dell Command | PowerShell Provider
I had a chance to test in JC cmd on my Lenovo box, let's dive into it.
As usual, create a new JumpCloud command -> Select Windows and PowerShell. Now pick a setting and put it in the first line - I'm using "WakeOnLANDock" as an example:

# Pick a setting to set
$settingName = "WakeOnLANDock"
# Getting the current setting
$currentSettings = Get-WmiObject -Namespace root\wmi -Class Lenovo_BiosSetting | Select-Object CurrentSetting
$currentValue = ($currentSettings | Where-Object {$_.CurrentSetting -Like "*$settingName*"}).CurrentSetting.replace(',','=')
$settingValues = (gwmi –class Lenovo_GetBiosSelections –namespace root\wmi).GetBiosSelections($settingname).selections
Write-Host "Settings available for $settingname : $settingvalues"
Write-Host "The current setting is $currentValue"
# Setting the new value
$newValue = $settingvalues.Split(',')[1] # Pick and choose a value, in this case is "disable"
Write-Host "$settingname is going to be set as $newvalue.."
$setSettings = Get-WmiObject -Namespace root\wmi -Class Lenovo_SetBiosSetting
$setSettings.SetBiosSetting("$settingName,$newValue")
# Connect to the Lenovo_SetBiosSetting WMI class
Write-Host "Saving the bios setting..."
$SaveSettings = Get-WmiObject -Namespace root\wmi -Class Lenovo_SaveBiosSettings
$SaveSettings.SaveBiosSettings()
Save it and give it a run!
You can find the full list of the settings here from Lenovo. A few interesting settings:
BootMode
BootOrderLock
FingerprintSecurityMode
SecureBoot
P.S. I don't have Dell & HP boxes to test but they work similarly - especially HP, it uses the almost identical WMI classes. They should be able to work well with JC cmd like Lenovo.
