PowerShell Script to Get BIOS Settings.

by phaniprasad918 at 2012-12-14 04:36:08

Hi all,

This is Phani. I need a script where I can get the BIOS Power Management details to check whether the Wake-on-LAN is Enabled or Disabled despite of the PC Company.

Thanks in advance.

Hi Phani,

Unfortunately, what you want to accomplish is going to be vendor-specific. Fortunately, you can certainly use PowerShell to query vendor-specific WMI settings. For example, I’m running a Lenovo laptop and can query Lenovo bios setting with the following command from an administrator prompt:
PS C:\Windows\system32> Get-WmiObject -Class Lenovo_BiosSetting -Namespace ‘ROOT\WMI’ | ? { $_.CurrentSetting } | Sort-Object CurrentSetting | Format-Table CurrentSetting, InstanceName -AutoSize

Hi MattG,

Thanks a lot for your reply. Could you please tell me where can I find Lenovo ThinkCentre M82 - AK2 Desktop’s WMI settings.
by MattG at 2012-12-17 04:26:36
Lenovo settings are in the ROOT\WMI namespace. You can list all the WMI classes in that namespace with the following command:
Get-WmiObject -Namespace ‘ROOT\WMI’ -List | Sort-Object Name
