After replacing a system board on an HP notebook, what must you do if the MPM (Manufacturing Program Mode) is locked?

The correct approach when the MPM (Manufacturing Program Mode) is locked after replacing a system board on an HP notebook is to elevate the call to HP 2LS to obtain an MPM unlock key. This step is crucial because the MPM is a secure state designed to prevent unauthorized access or modification of the system configuration. By working with HP 2LS, you are engaging with the manufacturer’s support team, who have the necessary authority and resources to provide an unlock key that ensures the system board can be properly set up and configured.

Using the MPM unlock key from HP 2LS guarantees that the correct procedures are followed to maintain system integrity and security, which is particularly important in environments where device tampering or data corruption can occur. This method also ensures that any unique identifiers associated with the notebook, such as the serial number and UUID, are accurately reapplied—critical for warranty and support purposes.

Other options do not address the locked MPM scenario as effectively, since they either suggest alternative methods that do not involve manufacturer support or imply that manual entry can resolve the issue when, in fact, the use of the unlock key is necessary to properly reset the MPM state.
