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
