Chapter 1. Overview

ITadministratorsarealwayslookingforeasierwaystomanage

clientcomputerBIOSsettings,whichincludehardwaresettings

and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,andmodifythebootordereitheratclient

computersorremotely.

Using Windows Management Instrumentation

WMIisprovidedasastandardfeatureinmostWindows®operating

systems.Itprovidesapowerfulset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.
