vi Lenovo BIOS Setup using Windows Management Instrumentation Deployment Guide

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 asimplied
way to change these settings. Lenovo has developed aBIOS 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.
Using Windows Management Instrumentation
WMI is provided as astandard feature in most Windows®operating systems. It provides apowerful set
of functions, such as query-based information retrieval and event notication, 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.
