WMIC - how to use Lenovo SetBiosSetting method - wmic

Question

I have a prob calling SetBiosSetting method using WMIC (and also C#)
wmic /namespace:\root\wmi path Lenovo_SetBiosSetting call SetBiosSetting "SecurityChip,Active"
wmic /namespace:\root\wmi path Lenovo_SetBiosSetting call SetBiosSetting SecurityChip,Active
wmic /namespace:\root\wmi path Lenovo_SetBiosSetting call SetBiosSetting ("SecurityChip,Active")
that gives "Invalid Number of Parameters." error, but why ?
Lenovo BIOS Deployment Guide: http://download.lenovo.com/ibmdl/pub/pc/pccbbs/thinkcentre_pdf/hrdeploy_en.pdf
Any Idea ?
I cant use VBS or PowerShell ...
Thanks,Martin

Try this in C#:
ManagementScope scope = new ManagementScope(#"\\.\root\wmi");
//
// Make change(s)
//
SelectQuery queryRead = new SelectQuery("SELECT * from Lenovo_SetBiosSetting");
using (ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, queryRead))
{
using (ManagementObjectCollection queryCollection = searcher.Get())
{
foreach (ManagementObject queryItem in queryCollection)
{
ManagementBaseObject inParams = queryItem.GetMethodParameters("SetBiosSetting");
inParams["parameter"] = "WakeOnLAN,Disable";
ManagementBaseObject outParams = queryItem.InvokeMethod("SetBiosSetting", inParams, null);
string result = outParams["return"] as string; // "Success"
}
}
}
//
// Commit to BIOS
//
queryRead = new SelectQuery("SELECT * from Lenovo_SaveBiosSettings");
using (ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, queryRead))
{
using (ManagementObjectCollection queryCollection = searcher.Get())
{
foreach (ManagementObject queryItem in queryCollection)
{
ManagementBaseObject inParams = queryItem.GetMethodParameters("SaveBiosSettings");
inParams["parameter"] = "";
ManagementBaseObject outParams = queryItem.InvokeMethod("SaveBiosSettings", inParams, null);
string result = outParams["return"] as string; // "Success"
}
}
}
The PowerShell for this is:
(gwmi -class Lenovo_SetBiosSetting -namespace root\wmi).SetBiosSetting("WakeOnLAN,Disable")

I arrived at this post trying to find a way to use WMIC to get all the objects in the Lenovo_BiosSetting class. Your syntax got me on the right track. I had to change your WMIC query to this:
wmic /namespace:\\root\wmi path Lenovo_BiosSetting get
(Note the double back slash)
