What can running ePSA help ensure before a part is replaced?

Running the enhanced Pre-boot System Assessment (ePSA) is primarily designed to perform diagnostic tests on various hardware components of a system. The tests help in identifying any underlying issues with the system's hardware before a specific part is replaced. By running ePSA, technicians can ascertain whether other components are functioning correctly and if there are no additional problems that could affect the overall system performance.

This process is crucial because it not only validates the specific component in question but also ensures that the troubleshooting process is thorough. If other problems exist within the hardware that might lead to a repeat failure or affect the newly replaced part’s performance, these issues can be addressed beforehand, thereby improving the overall reliability of the repair.

In contrast, options regarding warranty status, compatibility with the operating system, and installation costs do not directly relate to the primary function of the ePSA, which is to assess the health of hardware components in a system.
