Set BIOS Password Using SetBiosSetting() Method

[DJC86]

Hello,

I am attempting to set a BIOS password on my machines using the HPBIOSSettingInterface WMI Object.  My question is do newer models of HP PCs support using the SetBIOSSetting() method to set a BIOS password on a workstation?

When I attempt to use the method, it keeps returning code "5", meaning "invalid parameter"

Here is the code I am attempting to run in PowerShell

$BIOS = Get-WMIObject HP_BIOSSettingInterface -Namespace "root\HP\InstrumentedBIOS"

$BIOS.SetBIOSSetting('Setup Password','<utf-16/>TheBIOSPassword','')

Is the above able to be used by all HP workstations?

Thank you,

Daniel

Nevermind - I found the problem:

I needed to include the encoding even though there isn't a password established.

So, instead of using this:

$BIOS.SetBIOSSetting('Setup Password','<utf-16/>TheBIOSPassword','')

I used this and it worked:

$BIOS.SetBIOSSetting('Setup Password','<utf-16/>TheBIOSPassword','<utf-16/>')

Hope this helps someone out in the future.

Thanks,

Daniel
