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.

ThefollowingillustrationshowshowWMIcanbeusedtoaccess
