Before installing a replacement part in a customer's HP workstation, what should you do?

Validating the issue to confirm that the original part is faulty is a critical step before installing a replacement part in a customer's HP workstation. This process helps ensure that the technician accurately diagnoses the problem and addresses the correct component. Replacing parts without first verifying the issue could lead to unnecessary replacements and additional costs for both the business and the customer.

By confirming that the original part is indeed faulty, the technician can provide reliable service and maintain customer trust. This methodical approach also helps avoid the potential waste of time and resources, ensuring that the problem is resolved efficiently.

On the other hand, reloading the operating system or returning the original part to HP Depot can be time-consuming and may not directly relate to confirming a faulty component. Similarly, while confirming the warranty is important, it is a more administrative step that should come after the technician verifies the fault in the original part. This administrative step does not directly aid in diagnosing the issue at hand.
