Chapter 1. Overview

IT administrators are always looking for easier ways to manage client computer BIOS settings, which include

passwords, hardware settings, and the boot order. The Lenovo BIOS WMI interface provides a simplified

way to change these settings. Lenovo has developed a BIOS interface that can be manipulated through

Windows Management Instrumentation (WMI). The Lenovo BIOS WMI interface enables IT administrators to

make queries on current BIOS settings, restore settings to their factory defaults, change single settings,

reset or change passwords, and modify the boot order either at client computers or remotely.

WMI is provided as a standard feature in most Windows

of functions, such as query-based information retrieval and event notification, which enables users to

manage both local and remote computers. The Lenovo BIOS WMI interface extends the capabilities of WMI

to allow management of BIOS settings.

The following illustration shows how WMI can be used to access Lenovo BIOS settings.
