HP Recommended
Product: HP Compaq 8100 Elite SFF PC
Operating System: Microsoft Windows 10 (64-bit)

I'm trying to change the BIOS language (or any other setting) of this device using WMI scripts, but the return code is always 6 (Access Denied) with the right password.

The password configured is the "Setup Password", the "Power-On Password" is empty.

 

The script I am using to change the setting is:

 

$Interface = Get-WmiObject -Namespace root\HP\InstrumentedBIOS -Class HP_BIOSSettingInterface

#Set a specific value for a specific setting when a BIOS password is set
$Interface.SetBIOSSetting("Setup Language", "English", "<kbd/>" + "020304050607")

 

The password is "123456", I am parsing the password using this method, but the error code is 6.

 

In this device, we have tried to remove the BIOS password and put it again, send the password encoded in "<utf-16/>" (even when I am sure the encoding of this device is KBD), but the script only works when the BIOS does not have a Setup Password set.

 

There is some lock on the BIOS that does not allow me to change the BIOS configurations with WMI when the BIOS has a password set?

Or there is a way to reinstall corrupted HP WMI classes in this computer?

 

Thanks in advance 😄
