X230 VB Script for Bios Settings

Question

Hello,
i use a VB Script to set the bios Settings (WakonLan, Boot order etc.). I use the Lenovo WMI Class for my script!
If a use a script from Lenovo "Lenovo BIOS Windows Management Instrumentation Interface Deployment Guide for Desktop" to read all bios Settings, missing the Settings for SpeedStepModeBattery and SpeedStepModeAC.
the script is:
On Error Resume Next
Dim colItems
strComputer = "LOCALHOST"
Set objWMIService = GetObject("WinMgmts:" & "{ImpersonationLevel=Impersonate}!\\" & strComputer & "\root\wmi")
Set colItems = objWMIService.ExecQuery("Select * from Lenovo_BiosSetting")
For Each objItem in colItems
If Len(objItem.CurrentSetting) > 0 Then
Setting = ObjItem.CurrentSetting
StrItem = Left(ObjItem.CurrentSetting, InStr(ObjItem.CurrentSetting, ",") - 1)
StrValue = Mid(ObjItem.CurrentSetting, InStr(ObjItem.CurrentSetting, ",") + 1, 256)
WScript.Echo StrItem + " = " + StrValue
End
My question has been forgotten (SpeedStepModeBattery & SpeedStepModeAC)?
if a use a script to set the bios Settings for SpeedStepModeBattery & SpeedStepModeAC, i got a error invalid Parameter!

for HP computers you'll need the HP BiosConfigUtility
check out their site: http://ftp.hp.com/pub/caps-softpaq/cmit/HP_BCU.html
you'll need to build a repset file. this is best done by getting the current config from a configured machine or from a machine that hasn't been modified, making your changes, and then setting the config on the target machine(s).
The user guide is not included in the download, but it is linked in the above page right at the top.   Once you have all the pieces you'll just need a script to put it all together.  note changing these settings will put BitLocker
in recovery mode if you're using it, so suspend it before making the change(s).
