2.EntertheproductnumberofthecomputerorpressAuto-detectbuttononthescreen.

3.SelectDownloadsanddrivers.

4.Followthedirectionsonthescreenandinstallthenecessarysoftware.

UsethefollowingstrategytopreventunnecessaryexpenseforreplacingandservicingFRUs:

•IfyouareinstructedtoreplaceaFRUbutthereplacementdoesnotcorrecttheproblem,reinstall theoriginalFRUbeforeyoucontinue.

•Somecomputershavebothaprocessorboardandasystemboard.Ifyouareinstructedtoreplaceeither theprocessorboardorthesystemboard,andreplacingoneofthemdoesnotcorrecttheproblem, reinstallthatboard,andthenreplacetheotherone.
