Strategy for replacing FRUs
Before replacing parts:
Ensure that all software fixes, drivers, and Unified Extensible Firmware Interface basic input/output system
(UEFI BIOS) downloads are installed before replacing any FRUs listed in this manual.
After a system board is replaced, ensure that the latest UEFI BIOS is loaded to the system board before
completing the service action.
•IfyouareinstructedtoreplaceaFRUbutthereplacementdoesnotcorrecttheproblem,reinstallthe
originalFRUbeforeyoucontinue.
•Sometabletshavebothaprocessorboardandasystemboard.Ifyouareinstructedtoreplaceeither
theprocessorboardorthesystemboard,andreplacingoneofthemdoesnotcorrecttheproblem,
reinstallthatboard,andthenreplacetheotherone.
•IfanadapteroradeviceconsistsofmorethanoneFRU,anyoftheFRUsmaybethecauseoftheerror.
