When is it appropriate to run ePSA after a part has been replaced?

Running the enhanced Pre-boot System Assessment (ePSA) after a part has been replaced is appropriate primarily to verify the effective installation of the new part. This diagnostic tool allows for confirmation that the replaced component is functioning correctly and that the installation was successful. By running ePSA, you can identify any potential issues that may have arisen due to the installation process, ensuring that the system operates as expected post-replacement.

This step is crucial for maintaining the reliability and performance of the system, as it helps to catch any errors that may exist immediately after a hardware change. Conducting this verification can save time and resources by identifying faulty installations or incompatible components right away.

While running ePSA only if the system still has issues or after every reboot may seem practical, these scenarios don't specifically address the importance of confirming the integrity of a newly installed component. Running tests solely before shipping also does not account for any potential issues that may arise post-installation.
