Hi guys,


The following script works perfectly on the older HP business pro machines such as HP  7900, 8100, 8300 desktops.

$Bios = Get-WmiObject -class HP_BIOSSettingInterface -Namespace "root\HP\InstrumentedBIOS" -ComputerName "xxx"
$Bios.SetBIOSSetting('Setup Password', '<utf-16/>test', '<utf-16/> ')


However, the script is unsuccessful with the newer machines such as HP Prodesk 600 G1, G2, G3, here is the output from the script. 


__GENUS : 2
__PATH :
Return : 32768 (Failure)
PSComputerName :


So, kindly help me on this matter.
